Abstract:
The experimental material comprising 28 F1`s, generated by crossing eight diverse lines of field pea in a half diallel fashion and their parents were evaluated in RBD in two replications at two locations during rabi, 2001-2002. The pooled analysis revealed that both gca and sca were influenced by environments which suggested that studies be conducted over environments to get unbiased estimates. The sca x E interaction was greater than gca x E interaction for most of the traits. The pooled component analysis revealed significance of both additive and dominance components. The parents Rachna, SKAU-P-4 and VL- I were found to be good general combiners for most of the traits. The best cross combinations in order by merit for seed yield were SKAU-P-4 x SKAU-P-10, VL-1 x Rachna and SKAUP-10 x Rachna. Diallel selective mating is advocated. Multiple crosses involving diverse parents can also be a viable approach for generating a wide genetic base population.
