Abstract:
The present investigation entitled “Genetics studies for seed yield and its contribution traits in Brasica rapa (L.) Var. Yellow sarson” was carried out in two environments timely (E1) and late sown condition (E2) at Research Farm of Genetics and plant breeding department, N.D. University of agriculture and Technology, Kumarganj during rabi, 2010-2011. Observations were recorded on days to 50% flowering, days to maturity, primary branches plant fruiting zone length (cm), number of siliquae on main raceme, seeds siliqua-1,1000-seed weight (g) seed yield plant-1, harvest index and oil content. Estimates of gca and sca variances and revealed that non-additive gene action was important in the expression of different characters in both the environments. The best five crosses namely NDYS 427 X NDYS 08-01, RAGINI X NDYS 116 -1, YST X NDYS 424 X NDYS 116-1 and Ragini X NDYS 07-02 were identified as good specific combinations for seed yield as well as some other traits. Highest heterosis for seeds yield plant-1 was 25.19% (jagriti X NDYS 08-01) and 115.77% (Ragini X NDYS 07-02) over better parent and standard variety, respectively in timely sown and in case of late sown condition it was highest as 30.62% (YST -151 X NDYS 425) and 91.50% (NDYS 427X NDYS 08-01) over better parent and standard variety respectively high estimates of heritability in narrow sense where observed for days to 50% flowering bracket (72%, 56%) plant height (88%, 82%) primary branches per plant (62%, 64%) fruiting zone length (83%, 85%) number of siliquae on main raceme (74%,71%) seats are siliqua silica 85% 82% seed yield per plant (45% 44%) and Oil content (38%,35%) in both the environment respectively.
