为提高三北98杂交油菜的制种产量，采用田间试验研究了不同施氮量对三北98杂交油菜制种母本产量及产量构成因素的影响。结果表明：在三北98制种母本施氮量为10～40 kg／667m2时，施氮量与制种产量的回归方程为 y＝54．8786＋2．6855x-0．061952x 2，R＝0．9668，F （2，4）＝28．63727，达极显著水平；且以施氮量为21．67 kg／667m2时的制种产量最高，达83．98 kg／667m2，其单株分枝数为42枝，有效角果为515角，角粒数为13．0粒／角，千粒重为4．65 g。

In order to improve the yield of Sanbei 98,a hybrid rape variety,a field experiment was conducted to explore the effects of different nitrogen application amount on seed yield and yield components.The results showed that the relationship between the seed yield and nitrogen amount of the female parent was y=54.878 6+2.685 5x-0.061 952x 2 when the nitrogen amount of the female parent was 10~40 kg/667m2 .When the nitrogen amount of the female parent was 21.67 kg/667m2 ,the actual nitrogen amount was 83.98 kg/667m2 and the effective branches per plant,pods per plant,seeds per pod and 1000-seed weight could be 42,515,13.0 and 4.65 g respectively.
