Effect of Genetic variability on Seed Yield and Oil Content in Indian Mustard [Brassica juncea (L.) Czern & Coss]

Ten parents of wide phenotypic differences and their 45F1S and 45F2S progenies were studied to assess the genetic variability among the parents and progenies for seed yield and oil content attributes for improvement in Indian mustard. The seed yield and oil content related to days to flowering, number of primary and secondary branches / plant, 1000 grain weight, length of main fruiting branches, harvest index exhibited significant differences among parents and the progenies but 1000 grain weight did not show any significant difference among F₁S and F₂S. Therefore, the direct and indirect selection efficiency through desirable characters is to be fixed for high yield. The range and variability are the measurements of parents and progenies, which will be supporting analogs for selection.
