Abstract: Genetic studies for fruit yield per plant and its attributing traits in brinjal was conducted by following line x tester mating design comprising of eight lines and four testers at Vegetable Research Station, Junagadh Agricultural University, Juangadh, Gujarat. The analysis of combining ability revealed the predominant role of non –additive gene effects in the inheritance of fruit yield and its component traits. The genotypes AB-15-07, NSR-1 and Swarna Mani Black, displayed high gca effects for fruit yield per plant and some of the desirable traits like; days to last picking, fruit length, fruit weight, number of fruits per plant and fruit borer infestation. The estimates of sca effects of the crosses indicated that eleven hybrids manifested significant and positive sca effect for fruit yield per plant. The crosses NB-15-5 x GJB-3, NBR-14-01 x Swarna Mani Black, AB-15-08 x Pant Rituraj, AB-15-07 x GJLB-4 and NSR-1 x Swarna Mani Black were emerged as best specific combinations. These crosses also showed desirable sca effect for important yield traits. These hybrids may be exploited for obtaining transgressive segregants toward developing hybrid varieties in brinjal.
