Desempenho de genótipos de feijoeiro comum, grupo preto precoce, no inverno de 2023, em Uberlândia - MG

Abstract

The common bean (Phaseolus vulgaris L.) is one of the most important species in Brazil as it constitutes one of the staple foods of the Brazilian population. The present work aimed to evaluate the genotypes of common beans, from the early black group, in the winter harvest of the year 2023. The experiment was conducted at the Água Limpa experimental farm in Uberlândia-MG, in a Cultivation and Use Value (VCU) trial, seeking to select the best genotypes to be launched as cultivars by Embrapa Arroz e Feijão. The agronomic characteristics evaluated were: number of pods per plant, number of grains per pod, mass of 100 grains and productivity in kg/ha. The experimental design used was randomized blocks (DBC), with 10 treatments (genotypes) being: CNFP17622, CNFP17959, CNFP18305, CNFP18313, CNFP18328, CNFP18316, CNFP18527, CNFP18535, IAC VELOZ and BRS CAMPEIRO, and 3 replications, totaling 30 plots. Each experimental plot consisted of 4 rows of 4 meters each, with a spacing of 0.50 m, totaling a total area of 8 m² and a useful area of 4 m². The experiment was carried out from 05/11/2023 to 08/17/2023. The data obtained were subjected to analysis of variance using the F test, and the Scott-Knott test was used to compare the means at 5% probability. The genotypes showed significant differences in all characteristics evaluated. The IAC VELOZ genotype was superior to the other genotypes in the characteristics number of pods per plant and number of grains per pod. The genotypes CNFP18305, CNFP18316 and CNFP18527 showed statistical differences in relation to the others when evaluating the mass of 100 grains. In terms of productivity, the genotype CNFP18316 stood out among the others as it showed an increase of 29.7% compared to the control.
