Stability Parameters in Lentil Genotypes

Abstract

Total 20 lentil genotypes were examined for assessment stability in different environments for grain yield in Southeastern Anatolia of Turkey. Genotypes and genotypes x environments interactions were significant for grain yield. The regression coefficient, deviations of the regression coefficients, coefficient of variation, ecovalence and stability variance were computed for genotypes. Genotypes FLIP2011-26L, ILL10975 and Firat 87 with a high stability (b) and high grain yield would be adapted to a wide range of growing conditions in a given production area with above average yield. The stability variance (σ2i) revealed that the lentil genotypes Kafkas, Cagil and FLIP2009-55L had the smallest variance across the environments, while the genotype Firat 87 had the largest stability variance (σ2i).
