With prime objective of developing season/region specific hybrid, the present investigation was undertaken to obtain the information on the per se performance, heterosis, combining ability, nature of gene action and stability parameters for fruit yield and its components in brinjal (Solanum melongena L.) using line x tester analysis at Navsari during 2014-15. Female parent, JBG-10-208 recorded the highest fruit yield per plant, while, PLR-1 was the highest yielding male parent. The best cross combination identified for fruit yield per plant based on pooled analysis was JB-12-6 ×PLR-1, which also displayed superior performance of other yield related attributes. The maximum standard heterosis for fruit yield per plant over both the checks was recorded by the cross combination JB-12-6 × PLR-1. Preponderance of additive gene actions for days to 50% flowering, plant height, primary branches per plant, fruit weight, fruit length, fruits per plant, fruit dry matter percentage, chlorophyll content, leaf area and total phenol. Non-additive gene actions were pre-dominant for secondary branches per plant, fruit yield per plant, photosynthesis rate, stomatal conductance and total soluble solids. It was recommended that inter se matings followed by pedigree method of breeding might prove useful for higher yield with better fruit quality. The cross combinations JBL-12-6-1-2 × Pant Rituraj and JB-12-6 × GJB-2 involving good x good general combining parents besides exhibiting favourable additive effect of good combiner parents, manifested complementary interaction effects for fruit yield and thus, resulted in higher sca effects. Hence, these crosses may be expected to yield transgressive segregants possessing enhanced yielding ability with stable performance.
