用三种授粉方式(普通去雄授粉,去雄授粉后不套袋,不去雄授粉)比较研究了对小麦×黑麦 F_0的结实率、饱满度、粒型、发芽势、发芽率的差异以及对 F_1的自然结实率与饱满度的影响,以便寻求一种既简便而又有效的杂交方式。结果发现,对与黑麦杂交结实率高的品种,采用不去雄授粉法是一种行之有效的方法,可在实践上使用。此法不仅保证杂种 F_0结实率不降低,而且对 F_0的发芽势、率上也有显著的改进,但对 F_1的结实率与饱满度无明显的影响。
The differences of seed setting rate, plumpness, grain shape, germination potential and germination rate of wheat × rye F_0 were compared with three pollination methods (ordinary male pollination, no pollination after pollination, no pollination) As well as the effect of F_1’s natural seed setting rate and plumpness in order to find a convenient and effective hybridization method. The results showed that the non-male pollination method could be used effectively in the hybrids with high seed rate of rye. This method not only did not reduce the seed setting rate of hybrid F0, but also significantly improved the F0 sprouting potential and rate, but had no obvious effect on F_1 seed setting rate and plumpness.
