Abstract: The experimental material comprised of six generations (P1, P2, F1, F2, BC1 and BC2) derived from five crosses (Parbhani Kranti x Shagun, Arka Anamika x PBN-1, Shagun x AKO-107, Akola bahar x PBN-13, AKO-107 x Pusa sawani) between different parents (Parbhani Kranti, Arka Anamika, Shagun, Akola Bahar, AKO-107, PBN-1, PBN-13, Pusa Sawani) along with check Ankur-40 (Hybrid). The material was evaluated during kharif 2013 in a randomized block design with randomization of generation replicated twice. The characters studied were plant height (cm), internodal length (cm), number of branches per plant, days to 50% flowering, fruit length (cm), fruit weight (g), fruit diameter (cm), number of fruit per plant, fruit yield per plant (g), fruit yield per ha. (q).The scaling test indicated the presence of non‑allelic gene interaction in all the crosses. The crosses Parbhani kranti x Shagun and Akola Bahar x PBN-13 showed superior mean performance for fruit yield per plant. However the cross Parbhani kranti x Shagun depicted superior performance for maximum number of characters studies. Superior hybrid was developed from the combination of parents Shagun and Ako-107 and for economically important traits like fruit yield per plant compared with P1, P2, F1, F2, BC1 and BC2 parameter in its generation system. However, the cross Arka Anamika x PBN-1 showed superior performance compared with remaining four crosses. In most of the crosses, additive x additive type of gene action played an important role in the inheritance of days to 50 % flowering. Dominance type gene action was observed to be important in the inheritance of characters like yield per plant, plant height, fruit length and fruit diameter. Dominance type of gene action would favour for production of hybrids. Most of the characters under study showed duplicate type of gene action, as such, trangressive variation can be obtained in the characters. Complimentary type of gene action was observed to play an important role in the inheritance fruit diameter to greater extent.
