Abstract:
The present investigation was undertaken to evaluate seven parents and twenty one hybrids through diallel mating system to study general and specific combining ability effects and genetic analysis for various yield and yield related traits. In diallel analysis, the variance of the genotype for all the characters were highly significant indicating high genetic variability among the parents studied. Based on gca effects, the parent VRO-3 was declared as superior parent. Arka Anamika, VRO-4 and VRO-6 were identified as next better parents. Among the hybrids, VRO-4 × Arka Anamika, VRO-3 × VRO-4, VRO-3 × VRO-6 and VRO-3 × Arka Anamika were rated as best hybrids for exploitation of heterosis based on mean performance. The hybrids VRO-4 × Arka Anamika, VRO-3 × VRO-4, VRO-3 × VRO-6 and VRO-3 × Arka Anamika had high positive significant sca for the characters, first flowering node, and first fruiting node, no of branch/plant, Width of fruit, number of fruit/plant, no of seed/seed yield/plant. Incorporating these hybrids into multiple crosses may be a meaningful approach for tangible improvement of these traits. Hybrids were therefore suitable for breeding heterosis to improve fruit yields toward plants and other yield components.
