Abstract: The present investigation entitled “Studies in relation to commercial hybrid development in brinjal (Solanum melongena L.)” was carried out to generate information on nature and magnitude of heterosis. There was high heterosis response in most of the hybrids which supports the role of non-additive gene action. Significant positive better parent heterosis was observed in thirty one cross combinations viz., PPC x A.Nidhi, PPC x P. Kranti, PPC x SBPL-27, PPC x A.Kusumakar, PPC x SBW-11, PPC x GBL-1, PPC x GOB-1, PPC x PPL, PPC x L. Long, A.Nidhi x P. Kranti, A.Nidhi x SBPL-27, A. Nidhi x SBW-11, A.Nidhi x GOB-1, A.Nidhi x PPL, A.Nidhi x L. Long, P.Krati x A.Kusumakar, P.Kranti x PPL, SBPL-27 x SBW-11, SBPL-27 x GBL-1, SBPL-27 x GOB-1, SBPL-27 x PPL, SBPL-27 x L. Long, A.Kusumakar x L. Long, SBW-11 x GBL-1, SBW-11 x GOB-1, SBW-11 x PPL, SBW-11 x L. Long, GBL-1 x GOB-1, GBL-1 x PPL, GBL-1 x L. Long, GOB-1 x PPL (Table 9.3). Heterosis (%) over better parent ranged from -84.99 to 226.38 in SBPL-27 x A.Kusumakar and GBL-1 x PPL, respectively. Most superior cross combinations for better parent heterosis were GBL-1 x PPL, PPC x SBW-11, PPC x GBL-1, PPC x GOB-1 and A.Nidhi x P.Kranti exhibiting the heterosis (%) of 226.38, 82.03, 69.03, 67.36 and 64.54, respectively.
