Selection Parameters for Yield, its Components and Oil Content in Indian Mustard [Brassica juncea (L.) Czern & Coss]

Thirty six F₁s, 36F₂s hybrid combinations obtained from nine parents crossed in a dial lei fashion in Indian mustard (Brassica juncea (L.) Czern & Coss) were grown in complete randomized block design. Data were recorded on nine quantitative and one qualitative characters. Wide range of means was observed for all the ten characters. High value of phenotypic coefficient of variation (PCV) with their respective genotypic coefficient of variation (PCV) in both F₁ and F₂ analysis suggest that phenotypic selection may be useful. Parameteres of heritability, genetic advance, correlation and path analysis revealed that for enhancing seed yield/plant by selection in segregating hybrid populations major emphasis should be stressed largely upon five characters namely, test weight, secondary branches, plant height, primary branches and number of siliquae on main raceme.
