“…Except for the characteristics Height of insertion of the first pod, total number of pods per plant, average number of seeds per plant and average grain production, which reached CV of 31.66, 26.23, 27.16 and 32.27%, these higher CV results for these characters in bean culture are expected, since characters linked to production and controlled by several genes tend to be influenced by the environment. High CV values in the bean culture for characters linked to production have been previously reported by Baldissera et al (2014), Rocha et al (2014), Gerrano et al (2015) and Correa et al (2015).…”

The agronomic performance and heterosis of common bean genotypes were evaluated using the diallel cross between two cultivars IPR Uirapuru and IPR Campos Gerais and five local varieties BGU-1, BGU-7, BGU-13, BGU-36 and BGU-36 and its 21 possible diallel hybrids. The treatments were evaluated under greenhouse conditions in a randomized block design with ten replications, at the Empresa Mato-Grossense de Pesquisa, Assistência e Extensão Rural (EMPAER), in the county of Cáceres, state of Mato Grosso, Brazil. The characteristics were evaluated: average number of days for emergence, number of days for flowering, average height of insertion of the first pod, average final height of plants, average stem diameter, average longitudinal length of pods, average total number of pods per plant, average number of seeds per pod, average number of seeds per plant, average weight of seeds and grain production. Based on the set of analysis performed and the characteristics evaluated, it can be concluded that for the increase in production the combinations composed by the parents IPR Uirapuru × BGU-1, IPR Uirapuru × BGU-6, BGU-7 × BGU-1, BGU -7 × BGU-36, BGU-1 × BGU-36, BGU-25 x BGU-36 and BGU-13 × BGU-36 showed positive

“…In 2014-2015 in the State of Mato Grosso do Sul, an area of 17,100 ha produced 27,600 tons of grain, with an average yield of 1814 kg/ha (CONAB, 2015). However, in the CerradoPantanal ecotone, little information has been obtained on cultivar performance (Santos et al, 2011;Correa et al, 2015).…”

ABSTRACT. Evaluating genetic diversity among genotypes is important for providing parameters for the identification of superior genotypes, because the choice of parents that form segregating populations is crucial. Our objectives were to i) evaluate agronomic performance; ii) compare clustering methods; iii) ascertain the relative contributions of the variables evaluated; and iv) identify the most promising hybrids to produce superior segregating populations. The trial was conducted in 2015 at the State University of Mato Grosso do Sul, Brazil. We used a randomized block design with three replications, and recorded the days to emergence, days to flowering, days to maturity, plant height, number of branches, number of pods, number of seeds per pod, weight of 100 grains, and productivity. The genetic diversity of the genotypes was determined by cluster analysis using two dissimilarity measures: the Euclidean distance and the standardized mean Mahalanobis distance using the Ward hierarchical method. The genotypes 'CNFC 10762', 'IAC Dawn', and 'BRS Style' had the highest grain yields, and clusters that were based on the Euclidean distance differed from those based on the Mahalanobis distance, the second being more precise. The yield grain character has greater relevance to the dispute. Hybrids with a high heterotic effect can be obtained by crossing 'IAC Alvorada' with 'CNFC 10762', 'IAC Alvorada' with 'CNFC 10764', and 'BRS Style' with 'IAC Alvorada'.

“…This region has unique climatic attributes owing to its location in the transition zone between two national biomes: Cerrado and Pantanal . The agronomic performance of common bean genotypes in this region has been assessed by Corrêa et al (2015) and their results demonstrated that it is possible to exceed the current national average. However, studies are needed to investigate the temporal integration between genotypes x years, to evaluate the performance of genotypes over time.…”

ABSTRACT. The common bean, Phaseolus vulgaris, is predominantly grown on small farms and lacks accurate genotype recommendations for specific micro-regions in Brazil. This contributes to a low national average yield. The aim of this study was to use the methods of the harmonic mean of the relative performance of genetic values (HMRPGV) and the centroid, for selecting common bean genotypes with high yield, adaptability, and stability for the Cerrado/Pantanal ecotone region in Brazil. We evaluated 11 common bean genotypes in three trials A likelihood ratio test detected a significant interaction between genotype x year, contributing 54% to the total phenotypic variation in grain yield. The three genotypes selected by the joint analysis of genotypic values in all years (Carioca Precoce, BRS Notável, and CNFC 15875) were the same as those recommended by the HMRPGV method. Using the centroid method, genotypes BRS Notável and CNFC 15875 were considered ideal genotypes based on their high stability to unfavorable environments and high responsiveness to environmental improvement. We identified a high association between the methods of adaptability and stability used in this study. However, the use of centroid method provided a more accurate and precise recommendation of the behavior of the evaluated genotypes.
