STABILITY ANALYSIS OF SEED YIELD AND ONE HUNDRED-SEEDS WEIGHT IN DESI TYPE CHICKPEA GENOTYPES UNDER DRYLAND CONDITIONS

Authors

Abstract

In order to select high yielding and most adaptable chickpea lines under dryland conditions, seven desi type chickpea genotypes together with one check cultivar (Pirouz) were evaluated in three research stations (Gerize, Kharke and Ghamlu) of Kurdistan province, during three years (2001-03) in RCB design with four replications. Bartlett test suggested that there was homogeneity in error of variances. Thus, analyses of variance were done to study the genotype-environment interactions, and analysis of stability was done to determine the performance of lines in varying environments. Results, of ANOVA showed that there were significant differences among environments, mean yield of genotypes and the G E interaction. Stability analysis after Eberhart and Russell method showed that there were significant variations due to genotypes, environment and their interactions for one hundred seeds weight, and due to environment for seed yield. On the basis of stability parameters (P < sub>i, bi, S2di, and CV %), genotype ICCV 91006 with the highest seed yield (821 kgha-1) was selected as the most desirable and stable genotype .
