Özet

This study was conducted to determine the stability of grain yield and test weight, and the susceptibility index (S) of durum wheat under stress conditions. The genotypes were grown in replicated trials at Ceylanpinar State Farm in Southeast Anatolia under supplementary irrigation between 1992 and 1994, and in lowland and upland conditions in the Mediterranean region of Adana under rainfed conditions between 1992 and 1995. Stability parameters were estimated from the regression analysis as linear regression coefficient (bi) and coefficient of determination (r(2)), and from Kang's yield stability index (Ysi). Stress tolerances were estimated using stress susceptibility index (S).
