Published: May 2019

Rural transportation system is far behind when compared with urban transportation which resulted in decrease of rural transport demand. Therefore, for increasing the rural transport demand is needed a standards and concepts of rural transport for improving transport services both in infrastructure and facilities. Bus stop for rural transport is One of the support facilities that no avilable. This standar involves a specific standard for rural transport. The study was conducted in Jember and District Kalianda. The method used in this study is a qualitative and quantitative analysis. Analyses were performed using standard guidelines stop I stops of public transport which will be further developed a standard stop for rural transport. The analysis is based on the major facilities and supporting public transport standards issued by the Directorate General of Land Transportation can not be met properly. In other hands, planning of bus stop is appropriate but layout of bus stops at the intersection is outside the specified minimum standards. To obtain the size of the standard concept of bus stop (length: 3m-5meter ), location of bus stops that have noticed the condition of the land use and supporting facilities of bus stop such as pedestrian markings should be provided.Keywords: rural, bus stop, rural transport Sistem transportasi perdesaan memang jauh ketinggalan jika dibanding dengan transportasi perkotaan yang berakibat pada kurang diminatinya angkutan perdesaan. Untuk itu diperlukan suatu standar-standar dan konsep peningkatan pelayanan angkutan perdesan baik dari sisi prasarana dan sarana maupun dari kompenen utama dan komponen penunjang. Salah satu fasilitas pendukung yang belum ada standarnya adalah halte dan tempat hentian untuk angkutan perdesaan. Untuk itu diperlukan suatu standar khusus untuk angkutan perdesaan. Penelitian dilakukan di Kabupaten ]ember dan Kabupaten Kalianda. Berdasarkan hasil analisis diperoleh bahwa fasilitas utama dan penunjang sesuai standar angkutan umum yang dikeluarkan oleh Ditjen Perhubungan Darat tidak dapat terpenuhi dengan baik sedangkan dari sisi perencanaan sudah sesuai kecuali letak halte dengan persimpangan masih diluar standar minimum yang telah ditentukan. Untuk konsep standar halte diperoleh ukuran halte (panjang 5 meter-3meter), lokasi halte yang telah memperhatikan kondisi tata guna lahan dan fasilitas pendukung halte seperti marka penyeberang jalan harus disediakan.Kata Kunci : perdesaan, halte, angkutan perdesaan
â€œNarratives of Social Cohesionâ€: Bridging the Link between School Culture, Linguistic Identity and the English Language
Authors: De Kock Tarryn , Sayed Yusuf , Badroodien Azeem
Published: May 2019

This paper argues that processes of self-creation are significantly influenced by experiences of schooling, of which language forms a critical aspect. The school is a central site in which identities are contested, negotiated and affirmed, but it is also imbibed with a particular identity that, in the South African context, often remains expressly raced and classed. Existing research has pointed to the salience of language for questions of identity in education, and moreover the relationship between school cultures and the inculcation of particular norms and values. However, in the South African context research should also be focusing on the relationship between the major medium of instruction in schools, English, the values and behaviour encouraged at the school level, and how these influence learnersâ€™ linguistic and social identities. This paper engages with research conducted in three Cape Town schools and develops the idea of â€œnarratives of social cohesionâ€ to articulate the ways in which different school cultures influence learner-identity formation. It posits that the assumed neutrality of the primary medium of instruction, and its historic association with whiteness, represents a continued undervaluation of black learnersâ€™ linguistic and social experiences.
Democratic Citizenship Education: An Opportunity for the Renegotiation of Teacher Identity in South African Schools
Authors: Davids Nuraan
Published: May 2019

Curricular reform in South African schools, as initially encountered through outcomes-based education (OBE), and most recently in CAPS, has been criticised and interrogated, if not for its epistemology, then for its political desirability. While justifiable questions were and continue to be asked about the pedagogical adaptability of teachers to their new roles as facilitators of pre-determined outcomes, the same has not been said, or asked, about the preparedness of teachers to teach democratic citizenship education. It is necessary, therefore, to consider how prepared teachers are to teach and cultivate the principles of democratic citizenship education. Second, what considerations should be given to teacher identity in relation to democratic citizenship education? And third, how might South African teachers begin to take account of their identities and narratives, so that they might be placed to participate in teaching democratic citizenship education? In response, I argue that the contested nature of teacher identities makes possible particular contributions to democratic citizenship and democratic education, which are necessary for teaching democratic citizenship education.
A Cross-Cultural Experience of Microaggression in Academia: A Personal Reflection
Authors: Simatele Munacinga
Published: May 2019

Microaggression is defined as subtle and often unconscious or automatic actions or statements made towards a discriminated group. It causes distress, anxiety and isolation. Microaggression can often lead to demoralisation and a feeling that one is in a constant psychological warfare. It is also ubiquitous in nature. This paper is a reflection on my experiences of microaggression as a black female academic gathered from working in six universities across five countries and two continents. I use autoethnography underscored by critical race theory thinking. The reflection has a multicultural face and is done in light of the extant literature on gendered, racial and non-native microaggression in the academic world. I find close similarities in my experiences with others. I conclude that microaggressions are ubiquitous and are inevitable in a multicultural setting. Victims need to acknowledge microaggressions and be assertive in order to mitigate the associated negative effects. Further, counterspaces provide a very useful platform for challenging the inaccuracy of victimsâ€™ lived experiences and serve as a source of validation.
We Shall Fight, We Shall Win: An Activist History of Mass Education in India
Authors: Thapliyal Nisha
Published: May 2019

Social movements for public education challenge neoliberal claims that there is no alternative to the marketâ€”to the inevitability of the privatisation of education. This article analyses the ways in which education activists in India deploy critical histories in their struggles for a public and common school system. It is empirically grounded in a critical analysis of a 2016 activist documentary film called We Shall Fight, We Shall Win. The film was produced by a grassroots activist coalition called the All India Forum for the Right to Education (AIFRTE) as part of their ongoing struggles against the commercialisation and communalisation of education. The film provides a rare opportunity to explore different kinds of historical knowledge produced in collective struggles for equity and social justice in India. In particular, this analysis examines the ways in which activists link the past and the present to challenge and decentre privatised narratives of education and development. In doing so, this research offers situated insights into the critical histories that inspire, sustain and co-construct one site of ongoing collective struggle for public education in India.
The Making of a Colonial Archive: The Royal Commission on the Status of Women
Authors: Bunjun Benita
Published: May 2019

The Royal Commission on the Status of Women in Canada (RCSW), embedded in liberal hegemonic feminist ideology, is largely the landscape that influenced and continues to influence the simultaneous politicising and depoliticisation of the mainstream womenâ€™s movement in Canada since the 1970s. The testimonies and recommendations of the RCSW predominately represented the needs and voices of white, heterosexual, Anglophone and Francophone, able-bodied, middle-class women. Using an intersectional critical race feminist framework, this article analyses the â€œmakingâ€ of RCSW â€œagainst the grainâ€ in relation to discourses of nation-building and racialisation. Drawing on extensive historical archival data and relevant in-depth expert interviews, I argue that the RCSW as a colonial archive furthered nation-building projects while crystallising Indigenous women and women of colour as the Other. The article illustrates how the feminist organisation, Vancouver Status of Women, is embedded in the colonial archive of the RCSW, one that reproduced nation-building discourses of essentialism, racialisation, and exclusion.
â€œStudents Make History Every Day Just by Sitting on These Stepsâ€: Performative Spaces and Re-Genring in the South
Authors: Hunma Aditi
Published: May 2019

Studentsâ€™ call for decolonising the curriculum has triggered deep reflection about what we teach and how we teach it, but equally, about the role of pedagogic spaces in recognising students as agents in their learning. This paper is situated within the field of academic literacies, where studentsâ€™ engagement with texts is seen as being context-specific, and involving assertions of agency to various degrees. The added dimension here is the embedding of digital literacies, defined as a set of customised online practices, into a writing-intensive, first year, foundational course at a South African university, to favour the acquisition of academic literacies. The analysis of different spaces becomes crucial in grasping how innovative forms teaching and learning may take place. In his trialectics of space, Lefebvre distinguishes between perceived, conceived and lived spaces. Butler would refer to lived spaces as â€œperformativeâ€ ones, â€œcongealingâ€ into form through iterative use. Online learning spaces may well turn into performative spaces as students inhabit them, interact with online resources and explore their spatial boundaries. I perform a discourse analysis of studentsâ€™ textual practices on the online and physical spaces, to explore how students reproduce or subvert genre categories through processes of â€œre-genring.â€ Furthermore, I share the extent to which such pedagogic spaces become performative, the power dynamics that emerge, and their effects on our traditional conception of teaching and learning in higher education.
The fate of altertoxin II during tomato processing steps at a laboratory scale
Authors: Puntscher Hannes , Marko Doris , Warth Benedikt
Published: May 2019

The emerging Alternaria mycotoxin altertoxin II demonstrated substantial genotoxicity in vitro. Ubiquitous Alternaria ssp. frequently infest various agricultural crops, leading to economic losses and also potential food safety issues caused by associated mycotoxin contaminations. Due to the lack of commercially available reference standards, data on the general chemical behavior, the occurrence and the biological/toxicological effects of altertoxin II are scarce. Since tomatoes are particularly prone to Alternaria infestations, we simulated the storage and food processing of intact tomatoes and purees after altertoxin II-addition. We observed significant decrease in altertoxin II concentrations during storage at room temperature and particularly under thermal stress, by employing a validated LC-MS/MS method. Moreover, the reduction to the compound’s epoxide group to the alcohol, i.e. the formation of altertoxin I, was determined at considerable ratios in intact tomato fruits suggesting effective enzymatic xenobiotic metabolism.
Golden Opportunity: A Clickable Azide-Functionalized [Au25(SR)18]-Nanocluster Platform for Interfacial Surface Modifications
Authors: Gunawardene Praveen , Corrigan John F. , Workentin Mark
Published: May 2019

Ultrasmall atomically precise monolayer-protected gold thiolate nanoclusters are an intensely researched nanomaterial framework, but there is a lack of a system that can be directly synthesized and undergo interfacial surface chemistry. We report an [Au25(SCH2CH2-p-C6H4-N3)18]- nanocluster platform with azide moieties appended onto each surface ligand. The structure of this surface reactive cluster has been confirmed by single-crystal X-ray crystallography, mass spectrometry and UV-Vis, IR and NMR spectroscopies. We show that all surface azide moieties are amenable to cluster-surface strain-promoted alkyne-azide cycloaddition (CS-SPAAC) chemistry with a strained cyclooctyne, opening this as a new platform to allow functional, post-assembly surface modifications to this very prominent nanocluster.
A Computational Survey of Semiconductors for Power Electronics
Authors: Gorai Prashun , McKinney Robert , Haegel Nancy , Zakutayev Andriy , Stevanovic Vladan
Published: May 2019

Power electronics (PE) are used to control and convert electrical energy in a wide range of applications from consumer products to large-scale industrial equipment. While Si-based power devices account for the vast majority of the market, wide band gap semiconductors such as SiC, GaN, and Ga2O3 are starting to gain ground. However, these emerging materials face challenges due to either non-negligible defect densities, or high synthesis and processing costs, or poor thermal properties. Here, we report on a broad computational survey aimed to identify promising materials for future power electronic devices beyond SiC, GaN, and Ga2O3. We consider 863 oxides, sulfides, nitrides, carbides, silicides, and borides that are reported in the crystallographic database and exhibit finite calculated band gaps. We utilize ab initio methods in conjunction with models for intrinsic carrier mobility, and critical breakdown field to compute the widely used Baliga figure of merit. We also compute the lattice thermal conductivity as a screening parameter. In addition to correctly identifying known PE materials, our survey has revealed a number of promising candidates exhibiting the desirable combination of high figure of merit and high lattice thermal conductivity, which we propose for further experimental investigations.
A Cobalt-Iron Double-Atom Catalyst for the Oxygen Evolution Reaction
Authors: Bai Lichen , Hsu Chia-Shuo , Alexander Duncan , Chen Hao Ming , Hu Xile
Published: May 2019

Single atom catalysts exhibit well-defined active sites and potentially maximum atomic efficiency. However, they are unsuitable for reactions that benefit from bimetallic promotion such as the oxygen evolution reaction (OER) in alkaline medium. Here we show that a single atom Co precatalyst can be in-situ transformed into a Co-Fe double atom catalyst for OER. This catalyst exhibits one of the highest turnover frequencies among metal oxides. Electrochemical, microscopic, and spectroscopic data including those from operando X-ray absorption spectroscopy, reveal a dimeric Co-Fe moiety as the active site of the catalyst. This work demonstrates double-atom catalysis as a promising approach for the developed of defined and highly active OER catalysts.

THE EFFECT OF COMBINATION OF BORIC ACID AND LITHIUM CARBONATE ON SINTERING AND MICROSTRUCTURE IN SINGLE FIRING WALL TILE
Authors: ELMAS Savaş , TARHAN İsmail
Published: May 2019

The aim of this study was to determine the effect of boric acid and lithium carbonate on microstructure and sintering characteristics of wall tile after firing. Amount of Li2 (CO3) (0.1-0.3-0.6- 0.9-1.2-4 wt.%) were added in wall tile corresponding to each constant amount of added of H3BO3 (0.1-0.3-0.6-0.9-1.2-2 wt.%). All samples were fired in 1135 0C 35 minutes in an industrial fast firing kiln. Dry strength, fired strength, water absorption and colorimeter values of all samples were determined after firing. Scanning electron microscope (SEM), x-ray diffraction (XRD) analysis, optical dilatometer measurements were performed in order to determine the microstructure and melting temperature for prescribed purpose (1-2-7-8-11-32-37). Standard (1) and alternative (8) receipe’s thermogravimetric and diferantial thermal analyses were performed. 37 (2% H3BO3 + 4% Li2 (CO3) recipe’s sintering starting temperature was 984 0C. In the recipe 8 (0.3% H3BO3 + 0.1% Li2(CO3) is an alternative to the standard wall tile, which can be used with higher strength values.
Getting to Know Science Tweeters: A Pilot Analysis of South African Twitter Users Tweeting about Research Articles
Authors: Joubert Marina , Costas Rodrigo
Published: May 2019

Against the backdrop of the increasing relevance of social media in public science communication and engagement, this study aimed to expand our understanding of the relationships and interactions between social media users and scientific outputs. In order to do so, we explored the identities, characteristics and activities of South African science tweeters (or ZA science tweeters)—i.e. Twitter users in South Africa who tweet about research articles. The growing number of ZA science tweeters, both overall and in relative terms, suggests that Twitter users are increasingly using this social media platform as a tool to share and discuss scientific outputs. ZA science tweeters are actively contributing to the sharing of information about new research articles, but, in line with global trends, the bulk of science tweets amongst South African Twitter users comes from a small number of active tweeters, and only 1% of ZA science tweeters had more than 20,000 followers. About 6.6% of ZA science tweeters are scholars (or researchers) themselves. Compared to science tweeters who are not scholars, the scholar-tweeters sent out tweets about research articles more frequently, are active on Twitter over longer periods of time, publish more original tweets and use hashtags more frequently to increase their engagement on Twitter. In their Twitter bios, these scholars typically use academic terms to describe themselves, thereby presenting themselves as experts on this social media platform. Astronomy, astrophysics, ecology and the environment emerge as the research topics that are most popular amongst ZA science tweeters.
'These Devils That Have Many Uses'
Authors: Zastre Sydni
Published: May 2019

Michel de Certeau’s 1970 monograph The Possession at Loudun recounts a series of alleged demonic possessions at the Ursuline convent in Loudun, France, in the 1630s. These events led to the arrest of a local priest, Urbain Grandier, who was charged as a sorcerer and executed for his supposed crimes. Rather than seeking to verify the truth of the possessions, this paper analyses them through a feminist lens, suggesting that the state of ‘possession’ gave the afflicted nuns an agency which was otherwise unavailable to them. Under the leadership of their clever prioress Jeanne des Anges, the possessed women used their new agency to target and eliminate Grandier, who can be seen as a representative or scapegoat for the patriarchy as whole.
'God is a Man Eater'

This article explores the relationship between Christian persecution under Roman authorities in Late Antiquity and the role that consumption rituals played within it. Considering the similarities between condemned pagan and gnostic consumption rituals, which were often accused of being cannibalistic orgies, this paper determines whether comparisons drawn between these condemned rituals and Christian ones had any tangible similarities, or if Roman authorities projected their prejudices and knowledge of pagan rituals onto the Christian in order to justify their continued persecution.
The Warren Commission, Postmodernity and the Rise of Conspiratorial Thinking in America
Authors: Lobo Emily
Published: May 2019

The era of post-modernity has completely changed the way that we see, recognize and question the world, and what we accept to be true. During and after the 1960s many witnessed the rise of a greater multiplicity of local narratives. Prior to this, the grand narratives of the past, such as religion, the Enlightenment, and science were taken as whole, singular truths. However, such metanarratives tend to ignore the individual experiences that do not fit neatly into categories constructed by major institutional authorities. This disconnection from the personal pushed more people to doubt, in favour of the narrative(s) where the Self is visible and heard. It can be argued that this revolution in thought, and meaning and narrative-making in America grew after the assassination of President John F. Kennedy in 1963. By examining Jean-Francois Lyotard’s theory of postmodernity, and those who expanded on his ideas, we can highlight how the assassination of JFK marked the onset and rise of the postmodern conspiracy theory. This includes the deconstruction of trust, the breakdown of “objective” reality and identity markers as well as the use of new mass media technologies, such as the film camera and the television.

Variables measured consist of height, leaf number, root length, and fresh weight of green mustard. Data were analyzed by univariate analysis of variance (ANOVA) at α = 0.05 level when significant it was followed by Duncan test. The results showed that compost with Katalek decomposer was the best quality compost compared to compost with Promi decomposer. Planting media which was a combination of compost and soil, whether using a Katalek or Promi decomposer could support growth of green mustard greens, especially at the level of 2:1. The best medium for green mustard was shown by the 2-part compost medium with the Katalek decomposer and 1 part of soil.Keyword: compost decomposer, high growth, leaf number, root length and wet weightABSTRAKPercobaan untuk mengetahui kualitas kompos terbaik yang dibuat dengan menggunakan dua jenis merek perombak kompos (Katalek dan Promi) sebagai media tanam tanaman sawi (Brasica rapa), telah dilaksanakan pada bulan Februari sampai Maret 2015 di Unit Pengolahan Kompos Balai Konservasi Tumbuhan Kebun Raya Cibodas Lembaga Ilmu Pengetahuan Indonesia (LIPI).

ABSTRACTCultivation of chili plants in the tropical greenhouse requires cooling as a solution of high temperature inside the greenhouse. One of the cooling system can be applied is root zone cooling. The aim of this research is to apply root zone cooling system to cultivation of chili plant in tropical greenhouse with substrate system, and to know the influence root zone cooling system on growth and productivity of chili plant. Plants are cultivated with a hydroponics substrate system using a drip irrigation system where the cooling pipe is buried inside the substrate medium. First treatment is cooling the root zone with cooled water and the substrate temperature of root zone cooling was 14.1-26.9 0C (CH treatment). Second treatment is cooling the root zone with no cooled water (ambient temperature), and the substrate temperature was 24.8-34.2 0C (NC treatment). The air temperature inside greenhouse was 29.4 0C and 24.7 0C, day and night. Due to lack of intensity of sunlight into the greenhouse, the plants sustain etiolating. However CH treatment produced higher fruit weight per plant compared with NC treatment. The weight of fruit per plant is 873.60 g and 546.00 g, for CH and NC respectively. The fruit size in the CH treatment also produced longer and heavier fruits than the NC treatment.Keywords: hydroponics of pepper, productivity, root temperatureABSTRAKBudidaya tanaman cabai di dalam rumah tanaman daerah beriklim tropis membutuhkan pendinginan sebagai solusi tingginya suhu udara di dalam rumah tanaman. Pendinginan yang dapat diterapkan salah satunya yaitu dengan pendinginan terbatas di daerah perakaran. Penelitian ini bertujuan untuk menerapkan teknik pendinginan daerah perakaran pada budidaya tanaman cabai di dalam rumah tanaman iklim tropika basah dengan sistem substrat, serta untuk mengetahui pengaruh pendinginan daerah perakaran pada pertumbuhan dan produktivitas tanaman cabai. Tanaman dibudidayakan dengan sistem hidroponik substrat dan sistem irigasi tetes yang di dalam media tanam dibenamkan pipa pendingin. Perlakuan pertama adalah pendinginan daerah perakaran dengan air yang didinginkan dan suhu media tanam yang didinginkan berkisar antara 14.1-26.9 0C (perlakuan CH). Perlakuan kedua adalah pendinginan daerah perakaran dengan air yang tidak didinginkan (suhu lingkungan) dengan kisaran suhu media tanam sebesar 24.8-34.2 0C (perlakuan NC), dengan suhu udara rata-rata 29.4 0C pada siang hari dan 24.7 0C pada malam hari. Tanaman mengalami etiolasi akibat kurangnya intensitas cahaya matahari yang masuk ke dalam rumah tanaman. Perlakuan CH menghasilkan bobot buah per tanaman yang lebih tinggi dibandingkan dengan perlakuan NC. Bobot buah per tanaman sebesar 873.60 g dan 546.00 g, untuk CH dan NC berturut-turut. Ukuran buah pun pada perlakuan CH menghasilkan buah yang lebih panjang dan lebih berat dari pada perlakuan NC.Kata kunci: hidroponik cabai, produktivitas, suhu zona perakaran

Con el objetivo de investigar la fluctuación en la concentración foliar de nutrimentos durante la estación de crecimiento, se llevó a cabo un estudio en cuatro huertas de higuera con sistemas de producción intensiva, en la Comarca Lagunera, Durango, México. Se realizó una caracterización del suelo, así como un muestreo y análisis foliar mensual, de abril a octubre, de N, P, K, Ca, Mg, Fe, Cu, Mn, Zn y Ni. Con respecto a la concentración foliar de nutrimentos, en la mayoría de los casos no mostraron diferencias significativas entre huertas, dentro de cada fecha de muestreo. La concentración foliar de N, Mg y Zn fue más alta al inicio del ciclo (abril-mayo) y después bajó durante el ciclo. Por otro lado, la concentración de P, Ca, Cu y Ni presentaron una concentración más baja al inicio que al final del ciclo, mientras que K, Fe y Mn no obtuvieron una tendencia definida durante la temporada. Todos los nutrimentos estuvieron dentro de niveles de suficiencia reportados en la literatura, a excepción de Ca y Mg que fueron más bajos, a pesar de lo cual no presentaron síntomas de deficiencia. Se concluyó que esta especie presenta variaciones estacionales grandes durante el ciclo, en la mayoría de los nutrimentos; por lo tanto, es recomendable que la toma de muestras foliares con fines de diagnóstico nutrimental se realice en junio, en el periodo entre el término de la cosecha de brevas y antes de cosecha de frutos, que fue cuando se registró menor variabilidad entre huertas.

El Agave angustifolia presenta una amplia variación morfológica, que con frecuencia dificulta su taxonomía. La diferenciación entre las especies de Agave, se hace a partir de características morfológicas homólogas e independientes entre sí, cuya variación puede ser ontogenética y genética. El objetivo de esta investigación fue caracterizar la morfología del A. angustifolia denominado ‘sacatoro’ del estado de Guerrero. La investigación se realizó de 2016 a 2017, en seis poblaciones de A. angustifolia y dos poblaciones como control, A. angustifolia Haw y A. cupreata. Se midieron 32 variables del tallo y hojas de plantas madre e hijuelos a cada ejemplar, de acuerdo con la guía técnica para la descripción varietal de Agave spp. Los datos se analizaron mediante componentes principales (ACP) y agrupamiento aglomerativo jerárquico (AJA). Las variables que permitieron discernir las poblaciones fueron: forma, borde, color y textura de la hoja, estrías en espinas laterales y longitud de la espina terminal, todas con una correlación positiva. Los resultados obtenidos del ACP y el AJA permitieron observar la relación entre variables y especímenes en función de los atributos morfológicos que comparten las especies estudiadas. A pesar de la variación morfológica entre el maguey sacatoro y el A. angustifolia Haw., se muestra una estrecha relación positiva entre ambos. Por lo que se infiere que las características fenotípicas que sub agrupan al maguey sacatoro, pudieran mostrar como resultado una posible variante de A. angustifolia Haw que permitiría ubicar taxonómicamente a este grupo para contribuir a la ordenación del género Agave y su conservación.

Este estudio se realizó en el ciclo primavera-verano de 2014 en San Mateo Atenco, estado de México, México, con el objetivo de estimar los componentes de varianza y la heredabilidad en 39 cultivares de haba e identificar material genético sobresaliente a partir de caracteres cuantitativos y cualitativos. Se utilizó un diseño experimental de bloques completos al azar con tres repeticiones. Los caracteres cualitativos se describieron de acuerdo con la guía técnica para la descripción varietal en haba del servicio nacional de inspección y certificación de semillas (SNICS). Los resultados mostraron significancia estadística (p≤ 0.01) entre cultivares para cada carácter cuantitativo. La heredabilidad en sentido amplio varío de 30.7 a 99%. El mayor rendimiento de semilla se registró en las colectas identificadas como T8 (4.16 t ha-1), T5 (3.9 t ha-1) y T 27 (3.8 t ha-1). El análisis de componentes principales explicó 65.2% de la variación total original y en éste se observó que el rendimiento se correlacionó positiva y significativamente con número de vainas, peso de vaina y peso de semilla. En el análisis de conglomerados se formaron cuatro grupos, de los cuales el tercero de éstos incluyó a las poblaciones de haba con los mejores descriptores agronómicos evaluados.
