论述了以穗和粒为基础的混合选择法对提高异质小麦群体抗稳发芽的作用。假定在相同生理条件下,根据籽粒大小来分选种子可提高选择效果;后代测试及红粒类型出现频率的变化表明穗选和粒选混合选择能有效地降低穗发芽;利用不同材料的群体分离,从中选择休眠材料的混合选择效果与从该材料中初步选择休眠材料的机理是一致的。这些结论对改良大量异质小麦群体抗穗发芽是很有价值的。
Discussed the ear and grain-based hybrid selection method to improve heterogeneous wheat population anti-stubborn role. Assuming that under the same physiological conditions, sorting seeds according to the grain size may improve the selection effect; the change of the offspring test and the appearance frequency of the red grain types indicates that the combination of ear selection and grain selection can effectively reduce spike germination; the separation of the groups with different materials , From which to choose the hybrid effect of dormancy material is consistent with the initial selection of the dormant material from this material. These conclusions are of great value for improving the resistance to sprouting of large numbers of heterogeneous wheat populations.
