Abstract

Thirteen genotypes developed for rainfed areas of Pakistan viz., NR-155, 97C027, SN-6, PR-72, BWL-9736, NR-149, 96R37, DN-14, V-97005, 95C004, NR-178, CHAKWAL-97, SN-16, were evaluated for stability of grain yield under twelve diverse environments. The interaction between the genotypes and environments (G X E interaction) was used as an index to determine the yield stability of genotypes under all the environments. Both predictable (linear) and unpredictable (non-linear) portions of variation were found to be significant indicating equal importance in determining the stability of grain yield. The genotypes "96R37" and SN-16" were the most adapted showing considerable good performance in the entire set of environments under study.
