ABSTRACT
Thirteen hybrids of chickpea along with their eight parental lines in diallel fashion excluding reciprocal were evaluated for genetic variability (GCV, PCV, heritability and genetic advance), heterosis over mid parental value, heterobeltiosis and economic heterosis over ckeck i.e. Pusa 256 for yield and seven yield component characters. Significant differences were observed among hybrids and their parents for all the characters studied. Maximium GCV and PCV were observed for biological yield per plant followed by seed yield per plant and number of primary branches per plant. High heritability was observed in all cross combinations and high heritability coupled with high genetic advance was observed in biological yield per plant. High heterotic effect over mid parental value was recorded in biological yield per plant, seed yield per plant and number of primary branches per plant. The Crosses C-201 × C-226 and C-216 × C-114 showed high heterobeltiosis for seed yield per plant and biological yield per plant. All F1 hybrids showed positive heterotic value of economic heterosis over standard check for number of primary branches per plant, seed yield per plant and biological yield per plant. The diverse magnitude of heterosis for different characters in F1 over the parental lines indicated over all dominance or positively acting genes and increased diversity among the parental genotypes in the appearance of heterosis.
