Abstract:

Twenty one crosses resulting from L x T mating design comprising of seven lines and three testers were studied to know the magnitude of heterosis over mid parent, better parent and a commercial check, Ravaiyya. The parents and the hybrids were evaluated during summer season, 2014. Among the 21 hybrids, nineteen, fifteen and eleven hybrids exhibited significantly positive heterosis for fruit yield per plant over mid parent, better parent and commercial check respectively. The maximum heterosis for fruit yield per plant was observed in the cross L7 x T1 (92.12%) followed by L7 x T3 (90.55%) and L7 x T2 (85.74%). The hybrid L7 x T1 also exhibited highly significant positive heterosis for number of primary branches per plant, days to 50% flowering, fruit length and number of fruits per plant so, these quantitative traits might be contributed to high heterosis for fruit yield in brinjal.
