Estimation of Nature and Magnitude of Correlation among Different Traits in Chickpea (Cicer arietinum L.)

Abstract

The present investigation aimed to study correlations among different traits in chickpea, specifically indicated that the traits —days to 50% blooming, days to maturity, harvest index (%), plant height (cm), number of primary branches per plant, number of pods per plant, number of seeds per pod, 100-seedweight (g), and seed output per plant. Compared to the matching phenotypic correlation coefficient, the estimations of genotypic correlation were greater. It could be the consequence of the environment's altering influence on the genotypic level of character association. Harvest index, number of seeds per pod, number of major branches per plant, number of pods per plant, biomass per plant, and 100-seed weight at the genotypic level all showed a statistically positive connection with the seed output per plant. At the phenotypic level, the following variables demonstrated a positive and significant correlation with seed yield per plant: harvest index, number of seeds per pod, number of major branches per plant, number of pods per plant, and 100-seed weight. These correlations showed that enhancing the aforementioned traits can increase seed output.
