A field experiment was carried out comprised of 11 parents, 30 hybrids and commercial hybrid ABH-1 (check) during summer season 2015, at Collage farm, NAU, Navsari. The analysis of variance for all the traits revealed that parents were found to be significant for all the traits studied, indicating presence of the considerable amount of genetic variability in the parental material tested. IIHR-587 x NSRP-1, IIHR-534 x NSRP-1 and IIHR-587 x NSR-1 significant and desirable heterobeltiosis and standard heterosis for fruit yields. Combining ability studies revealed non-additive type of gene action for fruit yield involved in the expression of traits. IC-0742241, IIHR-534 NSR-1 and NSRP-1 were good general combiners for fruit yield per plant. Top three yielded cross IIHR-587 x NSRP-1 (0.3) and IIHR-534 x NSRP-1 (0.28) good desired sca effect. The overall analysis based on gca effect, sca effect, heterobeltiosis and standard heterosis revealed that cross IIHR-534 x NSRP-1 and IIHR-587 x NSRP-1 may be use for commercial exploitation.
