Genetic Analysis of Various Traits in Oilseed Brassicas
First Online 27-10-2021|
Methods: All crosses (12F1) along with their parents (7 parents) were sown in randomized complete block design (RCBD) with three replications.
Result: The analysis of variance showed extensive variability among the genotypes. The physical appearance of interspecific crosses was intermediate. B. campestris showed significant GCA effects among lines and B. juncea among testers for seed yield per plant. General combining behaviour of B. campestris was better as compared to B. napus and B. juncea. The SCA effects were higher within species than among the species. This also revealed that within the species B. juncea had more SCA (17.45) than B. napus (9.82) and B. campestris (8.01) for seed yield. The SCA showed the improvement of B. Juncea, is the best than other two species. It is also concluded that to obtain better yield, crossing within the species is more appropriate than among the species. Moreover, to introduce novel traits in brassica species is possible through interspecific hybridization.
