水稻温敏核不育系33 S特性研究

摘要

The research expIored morphoIogical characteristics, fertiIity, and tralts re-Iating to outcrossing of 33S which was of good shapes in pIant and Ieaf, with Iow infertiIity temperature, earIy fIowering period, high fIowering rate before noon, and good tralts reIating to outcrossing.%对33S形态特征、育性、异交习性等进行了研究，该不育系属中熟中稻类型，株叶形态好，不育起点温度低，花时早，午前花率高，异交习性好，制种较易获得高产。
