水稻“三系”选育配套后,进一步克服不育系的繁殖和制种的各种障碍,是迫切需要解决的问题。研究水稻“三系”的开花习性,对于解决不育系的繁殖和制种中的产量问题,在理沦上和实践上都有重要意义。为此,我们观察了部分野败型不育材料和其相应的保持及恢复材料,部分野栽不育材料和保持材料的开花习性。 Rice “three lines” breeding supporting, to further overcome the sterile breeding and seed production of various obstacles, is an urgent need to be addressed. Studying the flowering habits of the “three lines” of rice is of great significance in resolving the problems of reproduction and seed production in sterile lines. For this reason, we observed the flowering habits of some wild-type sterile material and its corresponding maintainer and restorer material, some wild-type sterile material and maintainer material.
