| 摘要: |
| 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 EFFECT OF DIFFERENT POLLINATION METHODS AND PARENT COMBINATIONS ON THE HYBRIDIZATION BETWEEN WINTER WHEAT AND RYE |

| Abstract: |
| 1.When wheat varieties were crossed with rye,three methods were used:pollination without emasculation,pollination after emasculation without bagging and ordinary pollination with emascu- lation.When the first two methods were used,those wheat varieties easily crossed with rye,could obtaih a high percentage of hybrid seed. It was easy to distinguish the true hybrid seed from the false one, according to the kernal type and kernal colour.Hence,the method of pollination without emasculation was valuable to be u... |
