Abstract

Chickpea (Cicer arietinum L.) is a leguminous self-pollinating crop belongs to family-Leguminaceae (Fabaceae). The aim of a plant breeder is to identify or develop high yielding cultivars. In the present investigation, forty-one genotypes were grown in randomized block design research farm of Department of Genetics and Plant Breeding, CCS University Meerut U.P. during Rabi session of 2022-23 to investigate the genetic variability, heritability, genetic advance, character association and genetic divergence (D2) analysis for yield and its attributing characters. The result of analysis of variance (ANOVA) showed significant variation among all the studied characters. The Genotypic and phenotypic coefficient of variance (GCV & PCV) were recorded maximum for the numbers of seeds, harvest index, biological yield per plant, no of branches per plant, seed yield per plant and plant height indicating the presence of substantial amount of genetic variability among the studied genotypes. High heritability coupled with high genetic advance as percent of mean were shown for number of seeds per plant, biological yield per plant, harvest index, seed yield per plant, plant height and number of branches per plant. Selection based on these traits may be proved worthwhile. The correlation coefficient analysis revealed that the seed yield per plant was significant and positively correlated with numbers of branches per plant, number of pods per plant, hundred seed weight, harvest index and biological yield per plant. Path coefficient analysis signified that harvest index, biological yield per plant, number of seeds per pod, number of seeds per plant and plant height had the highest positive direct effect on seed yield per plant. The result obtained from the present investigation may be proved helpful in the selection of high yielding superior genotypes of chickpea.
