An experiment was carried out at oil seed Research Farm, Kalyanpur of C. S. Azad University of Agriculture and Technology, Kanpur, dyring Rabi 2010–11. 20 lines namely; Varuna, Maya, Urvashi, Basanti, Rohini, Pusa Bold, Kranti, NDR-8501, Pusa bahar, Pusa Barani, Pusa jai kisan, Vaibhav, Durgamani, Ashirvad, KR-5610, B-85, Vardan, Nav gold, RH-30 and RLM-198 Used as female and 4 testers namely; Pusa agarni, RK-9807, RK-9808 and Mathura rai used as male were crossed in Line x Tester mating design. 104 treatment (80 F₁s + 24 Parents) were evaluated for 12 characters viz., days to flower, days to maturity, number of primary branches per plant, number of secondary branches per plant, number of seeds per siliquae, number of siliquae per plant, plant height(cm), 1000-seed weight(g), biological yield per plant(g), harvest index(%), oil content(%) and seed yield per plant(g). The results indicating that non-additive type of gene action was more prevalent than additive type of gene action for most of the traits. Estimates of higher heritability coupled with high genetic advance were found for days to maturity, number of primary branches per plant, number of secondary branches per plant, number of siliquae per plant, 1000-seed weight, harvest index and seed yield per plant. Seed yield per plant were found significant correlated with days to flower, days to maturity, number of primary branches per plant, number of secondary branches per plant, number of siliquae per plant, plant height, biological yield per plant, 1000-seed weight, harvest index and oil content at both genotypic and phenotypic level.
