Authors: Pineda Johana Raquel , Mereles Juan Ignacio
Published: February 2024

La expansión de la educación a distancia, impulsada por las Tecnologías de la Información y la Comunicación (TIC) y acentuada por la pandemia de COVID-19, ha transformado el proceso educativo. Este estudio se enfoca en la percepción de estudiantes universitarios en Paraguay respecto a las clases virtuales implementadas en 2022. A través de un enfoque cuantitativo y un diseño transversal, se recopilaron datos de 53 estudiantes de un curso de Programación Lineal mediante un cuestionario de Google Forms. Los resultados revelaron que, mientras los estudiantes mostraron satisfacción con la interacción y acceso a recursos en la plataforma virtual utilizada durante el desarrollo de las actividades, la preparación para el cambio de modalidad fue percibida como no muy satisfactoria. El análisis de correlación sugirió la idoneidad para aplicar un Análisis de Componentes Principales (ACP), que identificó dos componentes principales explicando alrededor del 70% de la variabilidad de los datos. La primera componente refleja la percepción general de los estudiantes sobre las clases virtuales, mientras que la segunda se centra específicamente en la opinión sobre las tareas asignadas por los docentes y el cambio de modalidad. El análisis descriptivo señaló que solo dos ítems relacionados con la plataforma virtual obtuvieron puntuaciones superiores a 3 (en una escala de 1 a 4), evidenciando áreas de mejora, especialmente en lo que respecta a la preparación para el cambio de modalidad. El ACP proporcionó una representación visual de la contribución de cada ítem a las componentes principales, destacando la importancia de la variedad y claridad de las tareas. En conclusión, este estudio ofrece una base empírica respecto a la percepción estudiantil durante la educación remota en la pandemia de COVID-19. Destaca la urgencia de mejorar la preparación para cambios de modalidad en situaciones de emergencia, así como la diversificación de las tareas asignadas por los docentes. Estos hallazgos no solo son cruciales durante la pandemia, sino que también tienen implicaciones directas en la evolución de las prácticas educativas posterior a la misma, apuntando a la mejora continua de la calidad en la educación a distancia.

Endodontic treatment aims to reduce bacterial contamination in permanent teeth with pulp necrosis. The success of root canal treatment is directly related to the neutralization and reduction of pathogenic microorganisms, so it is essential to carry out an adequate chemical-mechanical preparation and employ the use of auxiliary medications, in order to combat the maximum of resistant microorganisms. Among these medications, calcium hydroxide stands out for its breadth of beneficial properties to the canal and adjacent tissues, being the drug of first choice, as it has antimicrobial and repair-inducing characteristics.
The importance of psychology in controlling the behavior of emotions in traffic in the light of Skinner's theory and other contributions
Authors: Lira Louise Lorena Lopes , Lira Luiz Alberto Rocha de
Published: February 2024

The present study aims to analyze human behavior in traffic influenced by subjective emotions, considering the Brazilian case under analysis, as well as its circumstantial aspects. The country has in its statistics the highest number of deaths in traffic, with most caused by drunkenness, distractions and aggressiveness. Such reasons can also be caused by consequences of pre-conceived emotional states in other areas of life, be it professional, romantic, family or social. In this context, it is important to report on the role of psychology and the professional psychologist and the imminent possibility of their preventive contribution in a positive way in the prevention of accidents, analyzing the human being in his life trajectory and evaluating the superlative factors that may be influencing, and in some way, indicating reckless actions in traffic. In this way, a specialized diagnosis can help drivers to manage, drive and understand their feelings in a more balanced way, taking advantage of elements to reflect on their condition as a driver and their relationships in the social environment, through the act of driving in a context population in which there are established rules and norms. In another aspect, which adds relevance to the general objective and is important to support the theoretical foundation of the proposed study, it was to bring to this discussion, in the field of behavioral psychology, one of the main interventions in the works of Burrhus Frederic Skinner, one of the most important aspects of psychology in the behavioral area that dominated innovative practices and ideas in schools and clinics. Such interventions are remarkable in the sense of jointly explaining the repercussions of positive projects by psychologists so that institutions can further evaluate and value the aspects of mental health, not only as a restorative action by the professional, but also as a preventive action.

Published: February 2024

OBJECTIVE: This study aims to analyze the use of barbed sutures in minimally invasive procedures, considering safety, efficiency and reduction of surgical time. METHODS: The analysis included 43 articles selected from the PubMed electronic databases, using the descriptors "Barbed sutures", "Suture Suspension", and "Absorbable Knotless Barbed Suture". RESULTS: Among the selected articles, it was observed that the reduction in operative time provided by barbed sutures potentially cancels out the slight increase in cost and can also improve overall results due to shorter anesthesia time. The use of barbed sutures decreased the closure time in relation to standard sutures by 32.8%. The unidirectional barbed suture allows a higher concentration and more homogeneous distribution of soft tissues, avoids the subtle sliding of the edges of the sutured tissue, providing a safer and more stable environment for tissue healing, resulting in scars less prone to inflammation and, consequently, thinner and more imperceptible in an aesthetic analysis. The barbed suture is also seen as a useful tool in the plication of the rectus abdominis, being used in the fascia of the abdominal wall after the removal of the transverse rectus abdominis myocutaneous flap (TRAM) for breast reconstructions, for example, or associated with abdominoplasty. Although not a formal outcome of the study, the suture extrusion rate was 10% in the barbed suture group compared to 20% in the conventional suture group. In the study, the mean complication rate was 9.7% and the mean surgical time was 108 minutes for mammoplasty and 156 minutes for abdominoplasty. CONCLUSION: The present review demonstrated similar safety between the barbed suture technique and the conventional suture. Among the advantages of barbed sutures, it allows greater concentration and more homogeneous distribution of soft tissues, providing greater support with less tension on the thread, and better aesthetic results with less possibility of inflammation. Therefore, the data indicate an improvement in the complication rate, surgical time and safety for the patient in reduction mammoplasties and panniculectomies. It was concluded that barbed thread has greater applicability in plication of the rectus abdominis, superficial closure of the skin and accommodation of the deep layers in body contouring procedures. In the region of the arms, it is not applicable, as it can trigger problems in the healing of the surgical wound, due to a similar prolonged response of a foreign body by the sharper barbs and its slower absorption.

Authors: Santos Kessia Larissa Braga , Macena Cleidivan Silva
Published: February 2024

Teaching chemistry often presents challenges, especially in the context of public education, where limited resources and a lack of infrastructure can be obstacles. However, conducting simple and accessible experiments can overcome these difficulties, allowing students to experience chemical concepts in a concrete and interactive way. Thus, the problematic question that guided the development of this work was: "how to perform experiments with these limitations?" Based on this problem, the general objective was defined: "to arouse the interest of students in the discipline, promoting a practical and dynamic approach, which stimulates active participation and meaningful learning regarding the science content of the 9th grade of Elementary School of the Darcy Ribeiro Municipal School, located in the city of Imperatriz-MA". In this work, chemistry experiments that address the basic principles of the science discipline were chosen. These experiments have been adapted to be carried out with low-cost and easily obtained materials. Topics explored included chemical reactions, properties of matter, physical states, solutions and absorption, and bases. The choice of experiments was based on the school curriculum and the ability to arouse students' curiosity. The research involved different approaches, such as bibliographic research, field research, action research, and case study. The steps included the collection of information from bibliographic sources, the elaboration of experiments according to the content of the classes taught, the creation and application of interactive activities after the class, and the combined analysis of the results. The results suggest that a class that addresses experimentation possibly contributed to the development of a reflective and critical posture on the part of students, in addition to promoting a broader and more integrated understanding of the science subject.

Published: February 2024

This article assesses the state of the art in proposals for reforming the Individual Income Tax (IIT) in Brazil. Various discussions and proposals have been presented over the past years. The discussion regarding changes to the IIT regained momentum after the government introduced a proposal for consumption-based tax reform, leading to subsequent discussions in the House of Representatives and the Senate. Economic agents' expectation is that the next step will involve presenting a proposal for income tax reform. The purpose of this article is to discuss proposed changes in the design of the Individual Income Tax in Brazil by reviewing specialized literature and shedding light on these modifications. Thus, the article aims to evaluate three recurring questions in the IIT reform discussion: progressiveness and/or regressiveness; tax brackets, their corresponding rates, and legal deductions for medical expenses; and the taxation of profits, dividends, and investment funds.

Multidisciplinary relationships between holism and design
Authors: Esquivel Luz de Carmen Vilchis
Published: February 2024

In epistemology, part of philosophy dedicated to the multiple ways in which we approach the great questions of knowledge, there are types of knowledge, such as design, that cannot be explained only by their claims to true knowledge – as is the case with the so-called "hard" sciences – but by way of acquisition, the degree of order they establish in the world. the direction they provide to the lives of human beings and the progress they bring to humanity. This knowledge does not "accredit" the rationality of its conceptual structures (rationality that for many is synonymous with authority and hierarchy), despite being true, it is the knowledge coming from daily experiences or perception as is the case of design whose orders escape the common possibilities of verification and, as Bertrand Russell stated, [...] All knowledge of what is in the world, if it does not refer directly to facts known by means of perception or memory, is to be inferred from premises, at least one of which is known to us by means of perception or memory. (Russell, 1976: 136) In spite of these difficulties, it is valid to recognize as a starting point and methodological resource, the accumulation of phenomena that throughout history have been called "design" and the objects that emanate from it, called "the designed". This makes it feasible to find criteria to determine the object of study called "design" and once this is achieved, to establish the epistemological characteristics of the discipline being studied, this determines the so-called Design Theory. From this, it will be possible to create hierarchies and epistemological warps that are intradisciplinary – coming from the very essence of design practice and its particular methodology – multidisciplinary – linked to theories common to disciplines from common foundations, such as the visual arts, communication or architecture, among others – and interdisciplinary – emanating from the diversity of relationships between the disciplinary universe and design methodology. From whence originate, for example, the pedagogy of design, the psychology of design, etc.
Project of implementation strategies formation by alternation in education media técnico profesional

Published: February 2024

Technical-vocational education is one of the fundamental pillars that governs the educational system, and its strengthening is a task assumed by the Ministry of Education through the implementation of the National Policy on Technical-Vocational Training implemented through the National Strategy for Technical-Vocational Training. There are multiple challenges involved in carrying out actions to promote and generate instances of participation and decision-making that enable the involvement of all actors to articulate the educational system and economic development. In this sense, professional technical high schools with a specialty in preschool care assume a strategic and preponderant role in the education sector, since the young people who study the specialty put into practice what they have learned in classrooms and workshops allow them to effectively insert themselves into the world of work, access their professional practice and insert themselves into higher education. And, in most cases, to be an agent of change at the family level to improve the socioeconomic reality of their homes. For this reason, Chile needs to have technicians in the care of middle schools that will allow it to address the challenges of its own development and its growing participation in the preschool care system, with demands of greater added value, dynamic and challenging. In this scenario, alternation training will not only strengthen the specific technical competencies of the specialty, but also the capacity for innovation, entrepreneurship, teamwork, and a set of transversal competencies that will prepare students to work in multiple areas of education.

Published: February 2024

There are a number of techniques with which such horizontal impactions can be treated, with no single technique being favored over the other, as these all have pros and cons. Horizontally impacted third molars are usually indicated for extraction, and only in situations where the first or the second molar has to be extracted due to decay is when these are uprighted for replacement of the missing teeth. In contrast to vertically impacted molars there is a higher chance of success in uprighting horizontally impacted third molars as the cause is lack of space or blockage of the eruptive pathway.

A one-year-old Doe weighing 1.2 kg was brought to Teaching Veterinary Clinical Complex, FVAS, BHU-Mirzapur, with a history of giving birth to three dead bunnies 3 days before and after that not show any signs of kindling. Vulvul lips were swollen, congested and edematous. The Perineal area was smeared with uterine discharge. Doe had Inappetence dehydration for 3 days. Doe was previously treated with inj. oxytocin @ 1 to 3 IU I/M and inj. Epidosin @ 8mg/ kg I/M along with calcium gluconate @ 0.25 ml/kg slow I/V before 24 hrs. Abdominal palpation revealed the presence of fetal mass. Lateral abdominal radiograph showed the presence of one fetus’s skeleton located in the pelvic cavity. Based on the history and obstetrical examination it was diagnosed as a case of dystocia due to secondary partial uterine inertia. A male dead bunny was relived through exploratory laparotomy under general anaesthesia (premeditated with inj. xylazine 5 mg/kg body weight and induction with isoflurane 3-5%). Doe had an uneventful recovery following exploratory laparotomy with proper postoperative care. Dystocia due to secondary partial uterine inertia is a rare case in rabbits and it can be managed through exploratory laparotomy with proper post-operative care.

Published: February 2024

Az utóbbi évtizedekben a mezőgazdasági termelés gyakorlata és az élelmezési rendszer gyökeresen megváltozott. Az okszerűtlen mezőgazdasági gyakorlatok számos környezeti problémához vezettek, amelyek hatással vannak társadalmunk egészére is. Környezetkímélő, ugyanakkor gazdaságilag is hosszútávon fenntartható gazdálkodási formák és alternatív megközelítések azonban léteznek. Az agroökológia nem csak tudományos megközelítéssel, de társadalmi és gyakorlati oldalról is, komplexen támogatja a méltányos élelmezési rendszerre való áttérést. Az ENSZ Élelmezésügyi és Mezőgazdasági Világszervezete (Food and Agriculture Organization of the United Nations, FAO) kidolgozta az agroökológia 10 alapelemét, ami segítségül szolgál egy fenntartható, „helyreállító” gazdálkodási rendszer létrehozásában. A 10 alapelemből 4 kapcsolódik szorosan a természetvédelemhez, ezeket választottuk ki kutatásunkhoz: biológiai sokféleség, együtthatások, újrahasznosítás és rugalmas ellenállóképesség. A kiválasztott alapelemek gyakorlati megvalósulásának értékelése céljából vizsgáltuk a gazdálkodói és a fogyasztói oldalt. A gazdálkodói gyakorlat értékeléséhez mélyinterjút készítettünk két vizsgált gazdaság vezetőjével, a fogyasztók tudásának és motivációinak megismeréséhez pedig kérdőíves felmérést alkalmaztunk a gazdaság rendszeres vásárlói között. A kérdések összeállításához releváns szakirodalomra alapozott indikátorokat határoztunk meg, amelyekhez interjú/kérdőíves kérdéseket rendeltünk. A mélyinterjúk eredményei rávilágítottak arra, hogy mely gyakorlatok alkalmazásával teljesíti a két vizsgált gazdaság az agroökológia természetvédelmi vonatkozású alapelemeit. A gazdaságok fogyasztói körében végzett felmérés alapján megállapítható, hogy a vásárlókat tudatosság jellemzi, döntésükben nem csak az egészséges élelmiszer iránti igény dominál, de a környezetbarát és a fenntartható mezőgazdasági gyakorlatok alkalmazása is fontos szempont.
A Review and Categorization of Rain Depth and Rainfall Intensity Measurement Methods
Authors: Rácz Tibor , Waltner István
Published: February 2024

One of the essential factors shaping the Earth's surface and maintaining the life that has developed there is water. Water has a significant influence on the safety of human activity as well. The source of the surface water is mainly rainfall. Measuring the amount of rain has been an important issue for millennia and has become a scientifically based activity in the last few centuries. In the recent period, several methods have been developed for measuring and detecting precipitation and precipitation intensity, which provide data at different levels of accuracy. In addition to meteorologists and hydrologists, many disciplines use precipitation data included in professional publications without evaluating their accuracy. To evaluate the accuracy of precipitation data originating from a certain data source, the user needs to know its accuracy category and reliability. This article serves this purpose by presenting the rainfall measurement procedures from traditional catching measurements to radar, from satellite-based remote sensing to acoustic measurements, and estimation based on lightning statistics. It also presents the described procedures in tabular form, through which the user of the precipitation data can get an idea of the applied data’s accuracy.
First calculation of the implementable solar photovoltaic potential in Somogy county and its impact on CO2 emission reduction and job creation
Authors: Rodríguez-Segura Francisco Javier , Osorio-Aravena Juan Carlos , Muñoz-Cerón Emilio , Frolova Marina
Published: February 2024

Due to the current climate urgency, it is necessary to accelerate an energy transition towards renewable energies. To this end, the European Union has set ambitious energy targets. However, in member countries such as Hungary, nuclear energy and fossil fuels continue playing a major role in the energy mix. Nevertheless, this country has a large solar photovoltaic (PV) potential that is hardly exploited, especially in the southern counties, and its technical potential has been less analysed. With the aim to estimate the short-term implementable solar PV potential in Somogy county in southern Hungary, a multi-criteria spatial approach which integrates environmental, technical (with economic attributes), and geographical (with social-acceptability attributes) GIS-based constraints with existing local power plant considerations was employed. Results show that Somogy has a short-term implementable solar PV potential of 2.7 GWp This power potential is about 25 times more than the current installed capacity for generating electricity in Somogy and represents 45% of the national target by 2030 for installed solar PV capacity in Hungary. Furthermore, this potential could create almost 35,000 direct jobs and avoid the emissions of 1.16–2.65 MtCO2 to the atmosphere. The findings and future studies suggested in this work are significant for both local and national levels and could contribute with insights on how to meet climate targets and accelerate energy independence with socio-economic benefits.

White rust: Plant-microbe interaction and plant breedingperspective on Indian mustard
Authors: D PRAKASH  , K SRIVASTAVA  , B SINHA
Published: February 2024

White rust is an important disease of Indian mustard which results in appreciable yield losses. A monogenic dominant gene has been responsible for resistance against this pathogen in B. juncea. In the pathogen, avirulence has been observed to be dominant, governed by a single gene. R gene (resistance gene) present in resistant lines of B. juncea, encodes CC-NB-LRR (coiled coil nucleotide binding leucine rich repeat) protein whereas, susceptible lines have truncated LRR domain of the same protein. Resistant and moderately resistant lines have higher amount of chlorophyll, sugars and total phenols than susceptible cultivars, throughout crop growth. Increased accumulation of phytoalexins such as spirobrassinin, cyclobrassinin and rutalexin have been observed in resistant lines compared to, susceptible ones upon infection by fungi. Molecular markers tagged to R gene are being used in resistance breeding programmes. Scientists have developed intron polymorphism (IP) markers namely;At5g41560, At5g41940 and At2g36360 for positive selection of white rust resistance and, simple sequence repeat (SSR) marker, At2g34700, for negative selection of resistance in different rust resistant sources. The major issue in use of these markers is their transferability as they do not show association with R gene in different set of crosses.

Influence of sowing windows on seed yield ofsoybean [Glycine max (L.) Merill] cv. JS-335
Authors: C K PRAMILA  , T M RAMANAPPA
Published: February 2024

The soybean seed production has been limited due to lack of supply of quality seed; this is because soybean seed is affected by field weathering and environmental condition during pre and post-harvest period and thus loses its viability in storage and cannot be stored from one season to next. Therefore, the present study was conducted during 2020-21 and 2021-22 to determine the soybean cv.JS-335 breeder seed production feasibility in three seasons. The result revealed that, maximum number of pods (60/plant), pod length (4.25 cm), number of seeds per pod (3.12), test weight (75 g) and seed yield per acre (10.50 q) were recorded when soybean was sown during kharif season followed by summer as compared to Rabi season.

The experiment consisted of 24 sunflower inbred lines were evaluated with three checks (DRSF 108, DRSF 113 and Phule Bhaskar) respectively and was laid out in Randomized Block Design. The study illustrated, the existence of wide ranges of variations for most of the characters among the sunflower inbred lines. Analysis of variation indicated that the mean squares of the genotypes were highly significant for all the characters taken under study. The range of variation, as well as genotypic and phenotypic coefficient of variations were high for seed yield/plant, plant height and test weight indicating the scope of improvement through simple selection procedure for obtaining high yield. Broad-sense heritability estimate was maximum for plant height (98.5), while that for seed yield g/plant (97.4) and head diameter (95.6). Hence, higher heritability estimates for these traits indicated that environmental factors did not greatly affect phenotypic variation of these characters.

Two hundred genotypes with seven checks of Indian mustard were sown at two different interval (timely and late) in augmented block design for trait association and comparative phenotyping against heat stress at terminal stage. Correlation studies revealed that seed yield per plant had significant positive association with plant height, number of primary branches per plant, number of secondary branches per plant, leaf area index, total number of siliqua per plant, siliqua on main shoot and 1000- seed weight under both normal and late sown conditions. Based on results of heat screening parameters like heat susceptibility index, yield stability index and percent yield change, genotypes viz. NDRE-4, EC-399300, DRMR-13, DRMR-9, DRMR-7, DRMR-357, DRMR-6, EC-766423 and IM76 were found promising for terminal heat tolerance.

Authors: P S SRINIVAS  , H P MEENA  , M Y DUDHE
Published: February 2024

Among the 135 sunflower lines evaluated during summer, 2020-22, ten lines were confirmed resistant to leafhopper. Leafhopper (Amrasca biguttula biguttula) is a major sucking pest that occur mostly in rabi/summer season and cause yield loss of up to 40% in India. Chemical control effects pollinators. Host plant resistance is an ecologically and economically promising alternative pest management tool. Presently, none of the available hybrids are leafhopper resistant. Leafhopper resistant cultivars significantly reduces plant protection cost. Stable sources of resistance are needed to be identified to develop resistant cultivars.

Authors: M Y DUDHE  , M SUJATHA
Published: February 2024

The present study was conducted to assess the large scale diversity present among the 2146 sunflower germplasm accessions along with three checks and focuses on the identification of the diverse trait-specific working accessions for the development of the new inbreds which could be utilized in the development of the high heterotic hybrids in sunflower. The cluster means for eight characters of 2149 accessions were obtained, and a large range of mean values among the 14 clusters was recorded for different traits. For a given character based on cluster mean values, we can select highly divergent genotypes from the respective clusters for the development of new inbreds.

In the present experiment, 328 sesame genotypes were evaluated in Summer season 2021 with augmented block design at Project Coordinating Unit (Sesame and Niger), JNKVV, Jabalpur. Twelve quantitative traits were taken into consideration where significant variability was obtained for all the studied traits. The significant positive correlation was observed for primary branches/plant, secondary plant/plant, node to first flower, seed/capsule, capsule length, capsule/plant and plant height with seed yield/plant. On the basis of PCA, 5 PCs obtained more than one eigen value. Overall results revealed that traits and genotypes studied have a considerable level of variability which can be exploited in future breeding programmes.
Effect of provenance on flowering behaviour of parental lines of sunflower(Helianthus annuus L.) Hybrid-KBSH-78
Authors: T M RAMANAPPA  , C K PRAMILA  , M S UMA  , S D NEHRU
Published: February 2024

The study revealed that sowing of parental lines of sunflower hybrid KBSH-78 at different locations had no significant influence on plant growth specially flowering behaviour and seed yield. However, 50% flowering was observed at 57 DAS in male parent and 62 DAS in female parent i.e., female parent is late in 50% flowering by 5 days compared to male parent. In order to achieve the better synchronization between parental lines and also to enhance seed yield of the seed parent, male parent has to be sown late with two staggered sowings of 3rd and 5th day after sowing of female parent, irrespective of the seed production locations.

Authors: T MANJUNATHA  , C LAVANYA  , S SENTHILVEL
Published: February 2024

Castor yields depend not only on nature of sex expression but also resistance to biotic and abiotic stress. Changing climatic conditions like temperatures and rainfall patterns are adversely affecting sex expression pattern in parents and thereby seed quality and yielding ability of castor cultivars. Mutational breeding approaches are the best for generating desirable variability in pistillate lines. S-type pistillate lines containing dominant and epistatic genes for pistillateness and temperature sensitive recessive genes for the expression of Interspersed staminate Flowers (ISFs) are the most suitable pistillate lines. Male parent with the presence of both male and female flowers in each of the basal 3-6 whorls even under cooler temperatures are feasible to ensure pollination during hybrid seed production and also optimum maleness in castor cultivars. Diverse strategies are required for the development of parents, hybrids and varieties for rainfed and irrigated conditions.

Authors: A L RATHNAKUMAR  , DIVYA AMBATI
Published: February 2024

Linseed (Linum usitatissimum L.) is a traditional oilseed crop of India that represents a valuable alternative for cropping systems because of the high quality of the seed oil, which is being increasingly appreciated by consumers, food, cosmetic and eco-materials and industries. The aim of this study was to understand the linseed breeding and varietal development in India in the past to till now. Linseed is also grown in as many as 70 countries across the globe. Several varieties having high seed yield, oil content, Alpha linoleic acid (omega-3 fatty acid), seed colour, size and colour and resistance to wilt, powdery mildew, Alternaria blight and rust and few insect pests like budfly and Spodoptera have been developed globally. Even, to develop edible grade low (<5%) ALA lines like Solin in Australia and TL 99 in India have also been developed. However, a comprehensive analysis and historic review of the linseed varieties released in India and breeding methods employed in developing them has not been attempted so far. Hence, this paper aims at bringing out the historical fact on number of linseed varieties released and notified in India along with the breeding methods employed so that suitable breeding strategy can be formulated in improving production and productivity of linseed in India.
