控制授粉是培育新品种的常用技术,也是研究遗传规律,测定各种性状的遗传力的必要手段。一般情况下,控制授粉的第一步需要去雄、套袋,近年来各地又使用过多种人工隔离措施,如套麦管、去花冠、扎花瓣等来代替套袋。 Controlling pollination is a common technique for cultivating new varieties and is also a necessary tool for studying genetic laws and determining the heritability of various traits. In general, the first step in controlling pollination needs to be exhumed and bagging. In recent years, various kinds of artificial isolation measures have been used in various places, such as a set of straw, a corolla and a petal, instead of bagging.
