The field experiment comprised of four dates of sowing with six varieties of four Brassica species was conducted at the crop Research Centre of GBPUA and T Pantnagar during 2000-01 to 2002-03. Delay in sowing from 30 September to 14 November increased the number of days to 50% flowering but drastically reduced the number of days to maturity. Late sowing resulted in significant reduction in growth, yield and yield attributing parameters over 30 September sown crop. Similarly, dates of sowing had effect on quality parameters and significant reduction in oil and eurcic acid contents was recorded while protein, saturated fatty acids and glucosinolate contents in meal were significantly higher in later dates. Among the species, B. carinata took significantly more days to 50% flowering (112.0) and maturity (173.0) with highest dry matter accumulation/plant (50.5 g). Similarly, except seeds per siliqua, which were higher in NDYS _2 (B. campestris var. yellow sarson), rest all the yield contributing parameters were significantly higher in B. carinata var. Kiran. The seed and oil yield was also significantly higher in this variety followed by B. napus var. Hyola _401. The highest oil content (39.8%), saturated fatty acids (4.34%) and lowest glucosinolate (25.90 g/g fat free meal) and Erucic acid content (0.84%) were also recorded in B. napus var. Hyola-401 but the protein content was significantly higher in B. campestris var. NDYS-2.
