Abstract:
In order to evaluate the agronomic performance and estimate the genetic variability of 24 common bean genotypes grown in the Savanna-Pantanal ecotone and see, which characters can be used for selection of superior genotypes. Treatments consisted of 24 common bean genotypes (CNFC 10429, CNFC 10408, CNFC 10467, CNFC 10470, CNFC 10762, CNFP 10104, CNFP 10793, CNFP 10794, BJ4, CNFRJ 10556, VR3 VC3 e VC6, IAPAR 81, BRS Campeiro, BRS 7762 Supremo, BRS Esplendor, BRS Valente, BRS Pitanga, BRS Radiante, BRS Requinte, BRS Pontal, BRS 9435 Cometa e BRS Estilo). The following traits were evaluated: Early flowering, early maturity, height of the first pod, number of pods per plant, number of grains per pod, weight of 100 grains and grain yield. The following parameters were estimated: environmental, phenotypic and genotypic variances, experimental and genotypic coefficient of variation, genotypic coefficient of determination, b quotient, environmental, phenotypic and genetic correlations. The CNFP 10794 genotype had the best agronomic performance in the Savanna-Pantanal ecotone region. The population presents genetic variability and potential for selection of all traits. Based on genetic parameters estimates, the characters number of grains per pod and weight of hundred grains can be used in direct selection for more productive genotypes.
