Stability Analysis for Seed Yield in Lentils (Lens Culinaris MEDIK.) (original) (raw)

The development of genotypes, which can be adapted to a wide range of diversified environment, is the ultimate goal of plant breeders in a crop improvement program. In this study, linear regression were used to analyze the response to environmental conditions of lentil (Lens culinaris Medik) genotypes taking as independent variable (X) the average yield of all lentil genotypes in four experiences (two locations and two years). Yield stability was assessed by determining the coefficients of variation. Seven lentil genotypes were tested for seed yield in two locations of Southern Romania environmental conditions during 2008 and 2009 growing seasons. On the basis of the regression coefficient g enotypes Idlib-1, Idlib-2, Idlib-3, Hurani and Kurdi had general adaptability to over environments and genotypes Idlib-4 and Oana were suitable for favorable environments. The result of coefficient of variation indicated that the same genotypes were more stable. Among these Idlib-3 genotype was ...
