Abstract

This research was proposed to evaluate the behavior of grain yield of soybean genotypes tested under Goiás and Distrito Federal conditions (1986/87 to 1988/89). The statistic procedure used was the bi-segmented linear regression. The results indicated that only 14% of genotypes didn’t have their behavior explained satisfactory by the method used. It was suggested that the identification of promising genotypes should be based on the yield average (Yi) and regression deviations variance (s²di), as a top priority. The evaluation of the coefficients of regression (adaptability - bli and b2i) is interesting if the genotype shows high yield average and stable behavior (predictability -low s2di). Then, it was indicated the outstanding genotypes in each group of maturation cycle. It was also made productive behavior analysis of genotypes used as standard check to help in their choices in future trials.
