试验表明，在参试因素中，以 Ａ３Ｂ２Ｃ３Ｄ３为最佳组合，即采用 Ａ９８０６雄性不育系（Ｂ２）、开花后 ２ｄ（Ａ３）授粉３次（Ｃ３）、１６：００时（Ｄ３）授粉可获得较高的种子产量。在因素花龄、授粉次数、授粉时间及不同的雄性不育系中以花龄对种子产量、种子粒数及千粒重的影响最大，其次是授粉次数和授粉时间，雄性不育系对三者的影响最小。雄性不育系的授粉适期花龄为单复伞形花序完全开放后的２～８ｄ，其中以开花后４～６ｄ授粉的种子饱满，种子产量较高。 The results showed that A3B2C3D3 was the best combination, that is, A9806 male sterile line (B2) was used for pollination, pollination was performed 3 times (A3) 2 days after flowering (A3), and pollination was obtained at 16:00 (D3) Higher seed yield. The pollen age, pollination time, pollination time and different male sterile lines were the most influential factors for seed yield, seed grain number and 1000-grain weight. The second was pollination frequency and pollination time. Minimal impact. The pollination age of male sterile lines was 2 ~ 8 days after the unisexual umbels were completely open, in which seeds pollinated 4 ~ 6 days after flowering were full and the seed yield was high.
