G x E Interaction and Stability of Sesame (Sesamum indicum L.) Genotypes Over Environments

摘要

Twenty five genotypes of sesame were grown in three diverse environments to study genotype x environment (G x E) interaction and phenotypic stability for seed yield and its components. Sufficient G x E interaction was exhibited by all the genotypes for 1000-seed weight and seed yield. The contribution of linear and non-linear components of G x E interaction was different for different traits of interest. The genotypes viz., IVTS-05-04; IVTS-05-09 and IVTS-05-25 have stability for seed yield. These genotypes can be utilized to develop stable varienties having wider adaptability in future breeding programme.
