Abstract

In order to evaluate STABILITY ANALYSIS and also to study the relative contribution of the yield components under rainfed condition, an experiment was conducted using 17 genotypes of chickpea in a randomized completely block design (RCBD) with four replications in Kermanshah, Lorestan, Ilam, Gachsaran and Gorgan Research Stations for two years (2003-2004). Significant GENOTYPE × ENVIRONMENT INTERACTION, suggesting different responses of genotypes to different environments. The results of yield STABILITY ANALYSIS of genotypes (Eberhart and Russell) showed that genotype FLIP 97-114 had a better performance in different environment. Using within location variance and within location coefficient of variation genotypes FLIP 97-78 and FLIP 97-41 were identified as stable genotypes with high grain yield. Superiority index found genotype FLIP 97-78 as a stable genotype. Finally based on different STABILITY ANALYSIS methods, genotype FLIP 97-78 was considered as the most stable with genotype with high grain. The relative contribution of the number of seeds per pod was higher than that of number of pods per plant and 100 seed weight. It was also observed that the sensitivity of number of seeds per pod to the environmental fluctuations was less than that of the other two components, namely number of pods per plant and 100 seed weight, hence plays more important role in the yield stability of chickpea under different conditions of rainfed cultivation.
