水稻杂种优势的利用,三系育种是重要的途径,而三系选育的关键,在于有一个稳定的水稻雄性不育系。李泽炳认为,按照细胞质来源和恢、保关系进行分类,我国水稻雄性不育系可以划分为三个主要类型,即野败型、红莲型和滇一型。为了配合杂交水稻的生产实践,近年来,我们系统地进行了有关水稻雄性不育系及其相应的保持系花粉发育的细胞学观察,现将观察结果报道如下。
The utilization of rice heterosis, three lines of breeding is an important way, and the key to the three lines of breeding is that there is a stable male sterile line in rice. Li Zebing believes that according to the sources of cytoplasm and the relationship between restoration and conservation, the male sterile lines of rice in China can be divided into three main types, that is, wild-type, honglian-type and Yunnan-type. In line with the practice of hybrid rice production, in recent years, we systematically conducted on the male sterility of rice and its corresponding maintainer line of cytology observations, the observations are reported below.
