Stability analysis on seed yield and its components in peas
M. K. Ates, E. Ceyhan, S. Karadas, A. Kahraman
Abstract: Two cultivars and seven of newly developed pea lines were tested to determine the genotypic variability, heritability, adaptation and stable ability of individual lines for seed yield and yield components at Experiment Field of the Selcuk University, Konya, Turkey. The genotypes were evaluated in three years (2007, 2008 and 2009). Results from the combined analysis of variance indicated that there were significant differences between years and genotypes for the characters. The stability parameters were subjected to regression to determinate regression coefficient and deviations values. Differences in the response of environment were found between genotypes for all traits. The genotypes PS57 and PS53-1 were well adapted to seed yield in good environments. The best-adapted genotypes for seed yield in various environments were PS29-1, PS49, PS100 and PS48 lines. The common parts of the examined genotypes were exhibited specific adaptation ability to different environment; therefore, they represented a target to developing individual plant material for the purpose of breeding programs.
