Abstract

The aim of this study was to evaluate the adaptability and stability of soybean genotypes grown in two soybean producing micro-regions (301 and 401), in the harvest seasons of 2006/2007 and 2007/2008. 16 soybean genotypes were studied (six soybean lines of the breeding program of Monsoy Ltda. and 10 cultivars). The experiments were conducted in a randomized complete block design, with three replications. Individual and group analyses were performed and the parameters of adaptability and stability were estimated by the methods proposed by Eberhart and Russel, Annicchiarico, Linn and Binn and Centroide. The results showed interaction of genotypes and environments showing different behavior of the genotypes according to environmental fluctuations. The methods of Annicchiarico, Linn and Binns modified by Carneiro and Centroid, were consistent with each other and allowed to identify among the genotypes, the highest stability and adaptability. The cultivars M-SOY 7908 RR, M-SOY 8199 RR and BRS Valiosa RR have general adaptability and stability. The Strains LG4 and LG5, and cultivar M-SOY 7908 RR showed high adaptability and stability in favorable environments and the control M-SOY 8199 RR for unfavorable environments and the strain CC4 showed high stability and adaptability in favorable environments. The cultivars MSoy 8199 RR and BRS Valiosa RR had adaptation to unfavorable and general environments, considering the four methods that were evaluated in this study.
