Abstract
Fifty three genotypes of chickpea (Cicer arietinum L.) were evaluated for yield and nine other economic traits during rabi 2000-01 and rabi 2001-02 at the CSK HPKV, Research and Extension Centre, Berthin. The study revealed considerable genetic variability among the genotypes for all the traits. Genotypic and phenotypic coefficients of variation were more or less similar for all the characters. Phenotypic and genotypic coefficients of variation were high for seed yield per plant, biological yield per plant, pods per plant and 100-seed weight. High heritability coupled with high expected genetic advance was observed for seed yield per plant, biological yield per plant, 100-seed weight, pods per plant and plant height revealed the preponderance of additive gene effects in the expression of these traits. High estimate of heritability with low to moderate genetic advance observed for seeds per pod, days to 50 per cent flowering and days to 75 per cent maturity on the other hand revealed the importance of dominance and epistatic effects in the inheritance of these traits
