Abstract

A set of 21 premising genotypes of blackgram were evaluated in Summer, Kharif and Rabi seasons during 1983, 1984 and 1985. Pooled analysis of variance indicated significant differences among the genotypes and the environments. Moreover the genotype x environment interaction was highly significant indicating differential performance of the genotypes under varied environmental conditions. The genotypes UG 301, OBG 2, UH 28, OBG 1, UG 191 and T 9 showed higher yield and stability of yield performance. UG 301 and UH 28 were better adapted to rich environments, while T 9 was more suitable for poor environment and OBG 2, OBG 1 and UG 191 were well adapted to all environmental conditions.
