Studies on Heterosis in Brinjal (Solanum melongena L.)
International Journal of Current Microbiology and Applied Sciences
The present investigation was conducted to find out the heterosis in brinjal. The yield and yield attributing characters, viz. days to 50% flowering, number of primary branches plant -1 , plant height, fruit length, fruit diameter, number of marketable fruits plant -1 , weight of marketable fruits plant -1 , number of unmarketable fruits plant -1 , weight of unmarketable fruits plant -1 , total number of fruits plant -1 , total yield plant -1 and total yield ha -1 were worked out through line x
... out through line x tester analysis involving ten lines and three testers. All the thirty hybrids with their parents were grown in RBD with three replications at Vegetable Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar during 2013-14 and 2014-15 and pooled analysis was carried out for relative heterosis, heterobeltiosis and economic heterosis. For days to 50% flowering, maximum negative relative heterosis, heterobeltiosis and economic heterosis were shown by BB85 x Pant Samrat, BRLVAR 6 x DBL02 and PB 71 x DBL02, respectively. For total number of fruits plant -1 , high magnitude of relative heterosis and heterobeltiosis were shown by Swarn Syamli x Pant Rituraj and economic heterosis was shown by the PB 66 x Pant Samrat. For total yield plant -1 , high magnitude of relative heterosis and heterobeltiosis were shown by IBWL 2001-1 x Pant Rituraj and maximum economic heterosis was shown by SMB115 x DBL02. As regards to economic heterosis, the hybrids SMB115 x DBL02, PB 66 x Pant Samrat and IBWL 2001-1 x Pant Rituraj were observed as promising hybrids for different yield characters and can be exploited as commercial hybrids.
