ABSTRACT
The present study was conducted on varietal dynamics of yield stability in wheat during November 1996. The results indicated that Variety Chenab-79 not only produced higher mean seed yield across the locations and the stable variety having 0.8 bi. Furthermore, a significant linear trend was found between the varieties yields environment mean yields of the stable varieties. The result showed that varieties Pirsabak-91, Pak-81 and Chenab-79 proved to be the stable cultivars while Sarhad-82 Koh-I-Noor-87 and Chenab-70 as unstable. The three un-stable varieties were very sensitive to changes in the environment resulting in great variation in yield. It was concluded that these varieties yielded low in some locations but with the improvement in environment provided higher yields.
