Abstract
Fifty genotypes of durum wheat were evaluated over four diverse environments for grain yield and its component traits (tiller number, grains/spike and 100 grain weight). Genotype × environment interaction was found significant for all the traits except 100 grain weight. Further, linear component of G × E interaction was significant for 100 grain weight suggesting that the variation in performance of different genotypes could be predicted. The genotypes IDYT-CA-05-47, NI 146, PDW 215, IDYN 46 and IDYN 49 were found to desirable and stable across the environments for grain yield. Thus, these genotypes could be included in the hybridization programme to converge the stability characteristics of grain yield for the development of a stable variety adapted to wider range of environments.
