Comportamento agronômico de genótipos de feijoeiro comum, do grupo preto, no período de inverno, em Uberlândia – MG

Abstract

The common bean (Phaseolus vulgaris L.) is one of the main crops of grains produced in the country and in the world, because it is present in the most different cultivation conditions, the use of cultivars adapted to such is necessary. The present work consisted of an Intermediate Test (EI) test stage, evaluating agronomic traits of genotypes belonging to the National Program for Genetic Improvement of Embrapa Rice and Feijão Bean, at the Água Limpa farm of the Federal University of Uberlândia, during the period of 10 June of 2016 to September 21, 2016, with twenty genotypes of common bean (Phaseolus vulgaris) of the black group, with the objective of evaluating the number of pods per plant, number of grains per pod, mass of 100 grains and productivity in the winter season in the Municipality of Uberlândia - MG. The experimental design was a randomized block design with three replicates, consisting of 20 genotypes in a total of 60 plots, where each experimental plot consisted of two lines of four meters in length, which were spaced 0.5 meters apart , the useful area of ​​each plot being 4.0 m2. The results showed that there was no significant difference between the evaluated genotypes for the number of pods per plant, number of grains per pod and productivity. For the 100-grain mass, the genotypes IPR TUIUIU, CNFP 16404, CNFP 16419, CNFP 16459, CNFP 16383, CNFP 16373, CNFP 16425, CNFP 16379, CNFP 19416, CNFP 16402, CNFP 16384 differed from the others but not from the control IPR UIRAPURU.
