ABSTRACT
Breeders normally select simultaneously for several traits in various environments. We investigated the effects of the progeny x environment interaction on success in selection for several traits. The population used was obtained from a cross between the CVIII-85-11 line, which has a semi-erect to prostrate plant architecture and a cream with brown streaks bean type, and the BRS-Supremo cultivar, which has an erect plant architecture and black grains. In experiments conducted in the field, 47 progenies F(46) and F(47) were evaluated for two seasons for grain yield, plant architecture and grain type score. The variables were standardized and we obtained the sum of Z. The components of genetic variance in the average of the two environments were nil due to the progeny x environment interaction, which would hinder successful simultaneous selection of characters.
