Abstract:
The experimental material comprised of six generations (P1, P2, F1, F2, BC1 and BC2) through generation mean analysis of six crosses with different parents. The generations were analysed during kharif 2019 in Randomized Block Design with randomization of generations within each cross in two replications. The traits were studied plant height (cm), number of branches per plant, internodal length, days to 50% flowering, first flowering node, first fruiting node. The scaling test indicated the presence of non-allelic interaction in all the crosses. The PBNOK-6 x Pusa Makhmali and VRO-103 x Hissar Naveen showed superior mean performance in all the traits. In days to 50% flowering all crosses showed superior mean performance. In most of the crosses additive type (d) component showed superior performance in the characters first flowering node, number of branches per plant, internodal length. In all the six crosses days to 50% flowering was observed superior in all type of gene action. Additive x additive type (j) of gene action was observed to be important in the characters like number of branches per pant and internodal length. Most of the characters showed complementary type of gene action. Complementary type of gene action play role in transfer inheritance characters. Some characters showed duplicate type of epistasis. Its play important role for transgressive selection of the characters.
