title: Agronomic performance of experimental super sweet corn hybrids

description: ABSTRACT Super sweet is classified as a special type of corn, due to the presence of genes which promote sugar accumulation in grains, significantly reducing starch content in the endosperm. This study aimed to evaluate the agronomic performance of experimental super sweet corn hybrids, carrying the gene shrunken-2, in order to identify and select promising genotypes for Southern Brazil. The experiments were carried out in two sowing seasons in 2017/18, in the experimental field of UNICENTRO, Guarapuava-PR, Brazil. Thirty-two experimental hybrids resulting from an 8x4 partial diallel among super sweet corn inbred lines from four distinct populations were evaluated along with two commercial hybrids (BRS Vivi and Tropical Plus) used as checks. Traits of agronomic and commercial interest were evaluated: male flowering (MF), husk covering index (HCI), yield of husked ears (YHE), grain yield (GY), commercial prolificacy (CPR), percentage of commercial ears (PCE), color (COL) and soluble solids (SS) of the grains. We verified significant differences among the experimental hybrids, except for COL. There was no significant effect of sowing season regarding to SS. Genotypes x seasons interaction was significant for YHE, GY, CPR, PCE and COL. There are promising experimental hybrids showing performances superior to commercial super sweet corn hybrids used in Brazil. The experimental hybrids D2-61 x D5-41 and D3-10 x D5-43 were superior to the other experimental genotypes. The experimental hybrid D2-61 x D5-41 shows potential to meet the demands of the current super sweet corn market.

title: Arbuscular mycorrhizal fungi and phosphorus in spilanthol and phenolic compound yield in jambu plants

description: ABSTRACT Jambu has spilanthol and phenolic compounds that are responsible for several medicinal properties. Besides improving nutrient absorption, arbuscular mycorrhizal fungi (AMF) can change secondary metabolites’ yield. Thus, the aim of the current study was to evaluate AMF inoculation and P influence on shoot dry biomass yield, macronutrient content (N, P, K, Ca and Mg), total phenol contents and spilanthol percentage in jambu plants. The experiment followed a randomized block design at 3x4 factorial arrangement, with two AMF (Rhizophagus clarus and Claroideoglomus etunicatum) and without AMF, at four P doses (0, 30, 60 and 90 mg/kg of soil), with four replicates. Plants inoculated with R. clarus and C. etunicatum, grown without phosphate fertilization, presented increase by 23 and 12 times, respectively, in comparison to plants without AMF. The relative spilanthol area in plants inoculated with R. clarus, without phosphate fertilization, reached 2.4%. Shoot dry biomass yield of jambu plants and the P, K, Ca and Mg contents were higher when plants were inoculated with R. clarus at the lowest P doses. The AMF also increased the contents of total phenols in plants fertilized with 60 mg kg-1. This P dose increased spilanthol concentration in jambu plants inoculated with C. etunicatum.

title: Allometric models for non-destructive leaf area measurement of stevia: an in depth and complete analysis

description: ABSTRACT Leaf area measurement is pivotal for plant physiologists. Hence, accurate measurement of their leaf area is incredibly relevant in agronomic terms. The plant Stevia rebaudiana is a sucrose-free plant species that is now vital to the global production of sucrose-free foods. Here, we estimated S. rebaudiana leaf area using a nondestructive methodology comprising allometric equations. Through leaf length (L), leaf width (W), and/or their product (LW) the leaf area was determined. One thousand leaves were sampled from four distinct S. rebaudiana genotypes for model construction. Linear or power models were generated, and the best equation was selected using a statistical criterion. The statistical criteria indicated that the linear models best suited all genotypes tested, included a function of LW, exhibited increased stability, and precisely estimated coefficients. ANOVA revealed that both generalized and combined equations were feasible. Nevertheless, grouping all genotypes into a single model was not possible as the genotype leaf architectures were very dissimilar.

title: Influence of spacing and harvests on the production of scarlet eggplant and chicory under intercropping system

description: ABSTRACT The aim of this study was to evaluate the fresh mass of scarlet eggplant (kg/pl) and the number of leaves of chicory (nºf/pl) in relation to the spacing used by the farmers of the region for both crops. The experiment evaluated these crops under intercropping cultivation system, varying the number of chicory rows between scarlet eggplant rows as well as harvests (cycle of each crop), for intercropping and monocropping systems. The treatments were T1= scarlet eggplant 0.7x1.1 m (monocropping); T2= intercropped scarlet eggplant, 0.7x1.5 m, with four rows of chicory, 0.2x0.2 m between rows; T3= intercropped scarlet eggplant, 0.7x1.1 m, with three rows and chicory, 0.2x0.2 m; T4= intercropped scarlet eggplant, 0.7x1.3 m, with four rows of chicory, 0.2x0.2 m; T5= intercropped scarlet eggplant, 0.7x1.3 m, with three rows of chicory, 0.2x0.2 m; T6= chicory 0.2x0.1x0.4 m in two double rows, 0.2 m between rows, 0.1 m between plants and 0.4 m between double rows in 1.5 m linear area (monocropping) and T7= chicory 0.2x0.3 m with three simple rows in an 1.5-m area (monocropping). The experimental design was of strip blocks, in a 5x16 factorial scheme, consisting of five spacings of scarlet eggplant (monocropping), 1.5x0.7 m, 1.3x0.7 m and 1.1x0.7 m, alternating the number of chicory rows between rows and 16 harvests in time, once a week. For chicory, the design was also in a 6x12 factorial scheme, with six spacings. The spacing 0.2x0.2 m was intercropped with scarlet eggplant, alternating the number of rows and two monocroppings 0.2x0.1x0.4 m in double rows and 0.2x0.3 m with 12 harvests in time, being performed one harvest per week along with the scarlet eggplant. Intercropped scarlet eggplant in spacing 0.7x1.5 m showed higher averages in some harvests followed by spacing 0.7x1.3 m with four chicory rows between rows. Spacings 0.2x0.1x0.4 m and 0.2x0.3 m were the ones which provided the best averages for chicory crop, except for the 5th harvest, in which spacing 0.2x0.2 m consisting of four chicory rows provided the highest average (5.7 leaves/plant). Regardless of monocropping and intercropping arrangement used for chicory the Area Equivalence Index (IEA) was over 1.6.

title: Evaluation of okra landraces based on agronomic and biochemical traits

description: ABSTRACT Okra is consumed in several countries and is an important source of nutrients for human food. To promote okra production and consumption is essential the development of new cultivars with high nutritional levels, besides desirable agronomic traits. Thus, this study aimed to evaluate nine okra landraces by agronomic and biochemical traits. The accessions UEL2, UEL3, UEL5, UEL6, UEL7, UEL9, UEL10, UEL13 and UEL15 were grown in open field condition and evaluated in relation to fruit yield, fruit weight, fruit diameter, number of fruits per plant and plant height. The biochemical analysis included mineral composition, crude protein content, vitamin C content, total flavonoid and phenolic content and antioxidant activity. The UEL7 accession stood out for the high levels for biochemical traits such as content of some minerals, vitamin C and antioxidant activity. On the other hand, UEL3 accession had a low performance for biochemical traits, but stood out for agronomic traits such as fruit yield and number of fruits per plant. Hence, the UEL7 and UEL3 landraces may be introduced in breeding programs focused on human food and agronomic performance, beyond to contribute for okra germplasm conservation.

title: Genetic divergence of sweet potato genotypes based on morpho-agronomic traits

description: ABSTRACT Sweet potato is a vegetable of great importance in human consumption, due to its high nutritional value. It presents high phenotypic variation, with different forms of roots, leaves and vines. Given the above, we aimed to study the genetic divergence of sweet potato genotypes based on morpho-agronomic traits. The experiment was conducted in an experimental area of Unesp, Ilha Solteira Campus, located in Selvíria-MS. The experimental design used was randomized blocks with two replicates, including 200 genotypes and ‘Beauregard’ as a biofortified control. Shoot morphological traits of the genotypes were evaluated at 110 days and root morphological traits were evaluated at 127 days after planting. We used the obtained data to perform descriptive analysis, in percentage of phenotypic classes. In order to study genetic divergence, multivariate analysis was performed, grouping was done using Tocher’s and Ward’s methods. We also analyzed relative contribution of each trait for genetic divergence. Statistical analyzes were performed using Genes software and SAS. Wide genetic variability could be verified in the population studied in this experiment, being possible to obtain genetic gains in recombination between genotypes. Grouping using Tocher’s method was more effective for discriminating dissimilarity between genotypes. The low relative importance of leaf size, internode diameter and secondary peel color makes further evaluation of these traits unnecessary, reducing labor costs, cost and execution time.

title: Degenerescence of virus-free garlic cultivars in altitude conditions in the Semiarid region of the Northeast of Brazil

description: ABSTRACT It is necessary to use virus-free garlic seeds to reach high bulb yields; however, information is needed on the number of generations that these seeds can be grown in field conditions without decreasing bulb yield and quality due to degeneration. Degeneration is dependent on the production season and locality; thus, the objective of this work was to evaluate the degeneration of virus-free garlic cultivars grown in the Semiarid region of the Northeast of Brazil, through three experiments conducted in Portalegre, state of Rio Grande do Norte. Virus-free garlic cultivars were used in the first generation (G1) and second-generation (G2) and cultivars without clonal cleaning (infected) in the third experiment. The experiments were conducted in randomized blocks experimental design, with four replications. The treatments consisted of five cultivars: Amarante, Branco Mossoró, Cateto Roxo, Gravatá, and Hozan. The use of G2 garlic seeds in field conditions is viable, mainly for the cultivars Branco Mossoró and Hozan, which showed lower production losses. However, further evaluations, considering at least four generations, are necessary for these cultivars, since the degeneration level depends on the crop environment.

title: Selection of S3 progenies of super sweet corn based on agronomic performance of topcrosses

description: ABSTRACT The aim of this study was to select S3 progenies of super sweet corn based on agronomic performance, evaluated in topcrosses with the narrow genetic base tester Honey Sweeter (Seminis®). The experiment was carried out in Guarapuava-PR. We evaluated 22 topcross hybrids and three checks, in two sowing times, in randomized blocks design with three replications. Six traits were evaluated: total yield of husked ears, commercial yield of husked ears, grain yield, grain length, ear diameter and total soluble solids content. Considering the set of evaluated traits, the topcrosses with progenies D2-07, D3-28, D4-53 and D5-24 were superior to the others; therefore, these progenies should continue in the inbreeding process and be evaluated in crosses with elite inbred lines with potential to generate competitive super sweet corn single hybrids.
