dc.description.abstract The stability for yield performance and genotype x environment (GxE) interaction was studied in 12 wheat genotypes grown at 13 contrasting sites (12 in Sindh and one in NWFP) over two years. The combined analysis of variance over all environments revealed a highly significant (P ≤ 0.01) difference for genotypes, environments and genotype x environment interaction. An adaptation analysis was applied to estimate the b, s.e. (b) and deviation from regression coefficients (S2d) for each genotype. The genotype SI90157 produced the highest mean yield over all the environments showing wide adaptation and stability. Genotypes PN90111, Anmol 91, SP89126 and SH8921 gave the lower mean yield over all environments with high value of s.e (b) and s2d. The line SI88126 gave higher yield particularly in high yielding environments showing weak stability. The utilization of stable genotype SI90157 in the breeding programme for the evolution of new high yielding variety has been suggested. en_US
