湖北光敏感核不育水稻不育性的遗传规律

湖北光敏感核不育水稻不育性的遗传规律 ON THE STERILE GENETICS OF HUBEI PHOTOPERIODSENSITIVE GENIC MALE-STERILE RICE （Oryza sativa, subsp. Japonica, L） 张晓国 Zhang Xiaoguo 1 first-author 刘军 Lu Jun 1 朱英国 Zhu Yingguo 1 武汉大学生物系 武汉大学生物系 Department of Biology, Wuhan University Department of Biology, Wuhan University 本文用农垦58品种、矮杆农垦58S、鄂宜105S与农垦58S杂交,以花粉育性、自交结实率、自然结实率和单株目测四种育性指标签定植株育性。遗传分析杂种后代不育株和可育株的分离比例,结果表明:农垦58S的不育性是受一对隐性主基因控制。 Nong keng 58 and the photoperiod sensitive genic male sterile lines of dwarf Nongkeng58S, Ey105S & M105S were selected. They crossed with Nongkeng 58S respectively. The fertilities of plants in progenies were measured in accordance with the criterion of the percentage of normal pollen, self seed set, natural seed set and plant type. Genetic analyses were made on the basis of the ratioes of the fertile plants and the sterile ones. The results indicate that the sterility is controlled by one pair of recessive genes. 湖北光敏感核不育水稻 雄性不育性 遗传规律 Hubei Photoperiod Sentive Genie Male-sterile Rice male sterility heridity 国家自然科学基金(61672102) 1990-04-01 2021-04-01 4
