G X E Interaction and Stability of Elite Strains in Indian Mustard (Brassica Juncea Czern & Coss.)

Twenty eight genotypes of Indian mustard were grown in four diverse environments to study genotype environment (G X E) interaction and phenotypic stability for grain yield and its components. Sufficient G X E interaction was exhibited by the genotypes for all the characters except per cent oil content. However, characters differed with respect to the contribution of linear and non-linear components of GXE interaction. The genotypes PBR181, PBR171 and PBR 91 exhibited stability for seed yield and yield contributing characters. These genotypes can be utilized in future breeding programmes to develop high yielding strains having wider adaptability.
