A 5X5 half Diallel set was planned to study the combing ability and gene action for yield and its component traits in
Indian Mustard. Based on the findings of the experiment, two characters like No. of seeds per siliqua and Plant height shows
additive variance so Selection will be effective. All the characters study in the present experiment except No. of Branches
showed significant scar variance indicating the presence of non-additive gene action and due to this selection will not be effective
to improve the traits. It further gives us an idea to go for exploitation of Heterosis in these traits.
