Caractéres agronômicos de genótipos de feijoeiro comum, do grupo diversos, na época de inverno, em Uberlândia-MG

Abstract

Grown around the world, because of its edible seeds, the beans have a high nutritional value, being one of the main sources of protein, minerals, carbohydrates, calcium, iron and vitamins. Genetic improvement is based on knowledge of the specific characteristics of regions with potential for crop production, including socioeconomic, technological and edaphoclimatic conditions, seeking to overcome the problems that can arise from these conditions, with the objective of bringing new genotypes with greater efficiency and profitability. The present experiment is part of the Cultivation and Usage Value Test (VCU) developed by Embrapa Arroz e Feijão in different areas in Brazil and was conducted at the Experimental Água Limpa Farm of the Federal University of Uberlândia, Uberlândia-MG, in 2016 The experimental design was a randomized complete block (DBC), with 15 treatments and three blocks, totaling 45 plots. The treatments included the genotypes: CNFJ 15592; CNFRJ 15578; CNFRJ 15579; CNFRJ 15411; BRSMG UNION; CNFRJ 15577; CNFRJ 15404; CNFRJ 15576; CNFRJ 15581; CNFJ 15584; BRS RADIANT; CNFJ 15587; CNFRJ 15575; BRSMG ENHANCEMENT and the JALO EARLY witness. The evaluated characteristics were: yield (kg ha-1), number of pods per plant, number of grains per pod, mass of 100 grains (g) and final plants. The results showed that there was no significant difference in productivity, number of pods per plant and number of grains per pod among the evaluated cultivars. However, for the characteristic mass of 100 grains (g), the genotype that presented significant difference was: CNFJ.
