Study of Seed Yield Stability in Safflower Lines and Cultivars in Entezari Planting Under Rainfed Conditions of Kermanshah

Abstract

To study yield stability in some high yielding cultivars and lines of safflower, twenty five lines and cultivars were evaluated in a lattice design for three years (2000-2003) in Sararoud Dryland Agricultural Station in Kermanshah. Stability analysis based on Eberhart and Russell method showed significant difference at 1% probability level among genotypes for seed yield. Interaction effect of genotype and year was also significant. Line 338 and cultivar PI-258417 having yields more than total average (930.94 and 1031.92, respectively), line slope less than 1 and lower deviation variance of line were found to be more suitable for entazari plating under rainfed conditions of Kermanshah.
