Abstract

The selection of productive and consistent genotypes related to environment variations is the basic objective of genetic breeding of any cultivated species. Therefore, in order to quantify the genotype interaction in environments and also to study the grain yield stability, methods such as the bi-segmented linear regression (Cruz et al., 1989), Lin e Binns (1988) and the traditional method were used. The experiments were carried out in ten locations in Santa Catarina in the 2000/01 and 2001/02 growing seasons. Each assay was composed of 13 black bean genotypes, which were assessed in a randomized complete block design with four replications. Data showed that BRS Campeiro, AN 9021332, IPR Uirapuru and LP 98-5 genotypes had the best general adaptation. Genotypes with specific adaptation were also identified, although the only concordance among the methodologies was the indication of the IPR Uirapuru cultivar for favorable environments.
