Abstract
Seven F1 hybrids involving nine varieties/ lines of chickpea (Cicer arietinum L.) were evaluated to identify superior cross combination. The experiment was laid out in randomized complete bock design to estimate heterosis and heterobeltosis of grain yield and yield components. Significant differences among genotypes were observed in all the characters studied. The magnitude of hybrid vigour varied significantly between hybrids. Heterosis for plant height varied from -2.33% to 15.57%. The heterotic effects in primary and secondary branches varied from -20.06% to 58.52% and from -20.70% to 49.08% respectively. Heterosis for number of pods plant-1, number of seeds pod-1 and 100-seed weight respectively varied from 41.89% to 59.68%, 26.39% to 48.03% and -33.24% to 33.18%. Maximum heterosis and heterobeltosis for plant height and secondary branches were observed in cross combination K0014-10 × K0066-10 while cross K0019-10 × K0031-10 exhibited maximum heterosis and heterobeltosis for primary branches and number of seed palnt-1 whereas cross K0014-10 × K0052-10 reflect maximum heterosis and heterobeltosis 33.18% & 30.84% for 100 seed weight and for seed yield plant-1 97.37% and 76.47% respectively. Broad sense heritability for different traits studied ranged from 63.14% to 77.18%. High heterosis, heritability and genetic advance were observed for number of pod plant-1 which could be utilized for identification of best segregates from crosses K0031-10 × K0052-10, K0019-10 × K0026-10 and K0019-10 × K0031-10. Superior hybrids from this study could be used for the improvement of more than one character through selection of single plants with combination of various traits.
