Abstract
Effect of genotype x environment interaction was studied on relationship between yield and three yield components in 20 genotypes of chickpea. Significant differences were found between genotypes for the three yield components at all the locations. It was found that the pattern and strength of correlation between number of seeds pod-1 and yield, between number of seeds pod-1 and number of pods plant-1 and number of seeds pod-1 and number of branches plant-1 differed from location to location. The relationship of fruit bearing branches and number of pods plant-1 with grain yield remained positive at all the locations, though the strength of their correlation with grain yield was affected by environments. On the basis of this study it is proposed that importance should be placed on number of pods and number of fruit bearing branches while making selection from segregating populations for yield improvement.
