寻杂36制种母本始花后不同时段赶粉对产量的影响

Effect of Artificial Pollination at Different Time after Flowering on Yield of Xunza 36 in Seed Production

采用母本开花朵数标定法测定母本的异交结实数．结果表明，寻杂３６制种母本始花后不同时段对父本赶粉，产量差异极显著（Ｐ＜００１）；单穗产量变异平方和有７９９９％由母本开花朵数决定；

The signing way of female flowering numbers was used to determine seed bearing numbers of female allogamy.Results showed that the yield of Xunza 36 seed production was significant different under the artificial pollination at different time after female flowering(P<0 01).79 99% of yield variant square sum each ear was determined by the flowering numbers of female parent.The best time of artificial pollination was 70～80 minutes after female flowering.
