  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.

  Twenty genotypes of wheat were evaluated at thirty locations for stability parameters of grain yield. Genotype x Environment interaction was significant indicating the influence of environment on grain yield. Mean square due to genotype x environment was highly significant indicating genetic differences among genotypes for linear response to various environments. Stability using parametric approach only three genotypes namely V-97024, V-97112 and IBW-96405 satisfied criterion given by Eberhart and Russell (1966), but only one genotype (V-97024) was declared as a stable cultivator for grain yield considering high mean yield, regression coefficient (b) close to unity and low value of deviation from regression. Cluster analysis was also used to classify similar cultivars but the classification did not classify according to stability parameters. Therefore it is concluded that the conventional stability approach used by Eberhart and Russell and other parameters like ecovalence, deviation from regression and interaction variance should be used for categorizing cultivars.

  A set of twenty elite bread wheat lines including one standard variety were evaluated in order to determine the selection criteria for identification of high yielding lines in bread wheat. The results showed that all varieties having highly significant variation for days to heading, days to maturity, plant height, 1000-kernel weight, test weight and grain yield. Grain yield was positively correlated with 1000-kernel weight and test weight while the other traits i.e, days to heading, days to maturity and plant height showed negative correlation. The results indicated that 1000 kernel weight had positive direct effect on grain yield. It was concluded that selection be made considering 1000-kernel weight and test weight.

  Nine genotypes of wheat developed for rainfed areas of Pakistan viz., DN-18, NRL-9822, NR-200, V-99166, 98C013, V-3, PR-72, NR-181 and SN-7 were evaluated for stability of grain yield under seventeen diverse rainfed 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 during 2001-02. 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 genotype V-99166 was the most adapted showing considerable good performance in the entire set of environments under study.
