EFFECT OF GENOTYPE X ENVIRONMENT INTERACTION ON RELATIONSHIP BETWEEN GRAIN YIELD AND ITS COMPONENTS IN CHICKPEA [CICER ARIETINUM (L.)] AHMAD BAKHSH, MUHAMMAD ARSHAD* AND A.M. HAQQANI
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.
