Abstract: Two promising cotton (Gossypium hirsutum L.) lines viz., AEHM-74/11/89 and AEC-76/3/89 along with three commercial check varieties Chandi 95, NIAB-78 and Rehmani were evaluated for their yield performance under five contrasting environments having different agro-climatic conditions in the Sindh province. The genotypes were evaluated for their mean yield performance and stability analysis was worked out. Mean square of genotypes, environments and their interactions (G x E) were highly significant (P≤0.01). The advanced strain AEC-76/3/89 produced the highest mean seedcotton yield (2116.9 kg ha^-1) over all the environments with unit regression (b=1.11) and the lowest deviation from regression (S²d=0.047) value showing wide adaptation and stability. The local check variety Rehmani produced the lowest yield, whereas, NIAB-78 had comparatively low (1969.8 kg ha^-1) seedcotton yield with wide adaptability (b=0.91) and (S²d=0.089) over environments.
