1973年,作者在单季晚粳稻农垦58大田中发现了1株天然雄性败育株,该不育材料在长日照下表现不育,短日照下表现可育。1984年,中国农业科学院邓景扬研究员和湖北省有关专家分析了多年的研究资料,认为该材料受一对对光照长度敏感的隐性雄性不育基因所控制,国内外尚未见有先例,因而命名为“湖北光感核不育水稻”。该不育材料可以在短日照下自交繁殖,在长日照下杂交制种,一般粳稻品种都可作为杂交父本使用,杂种一代育性正常,有利于广泛地筛选强优势杂交组合。此外,该材料还可以作为水稻杂交育种的工具来使用。
In 1973, a natural male abortive strain was found in the single season late japonica rice Nongken 58 field. The sterile material showed infertility under long-day irradiation and fertile under short day. In 1984, researcher Deng Jingyang from Chinese Academy of Agricultural Sciences and relevant experts from Hubei Province analyzed the research data for many years and believed that the material was controlled by a pair of recessive male sterility genes sensitive to light length. No precedent has been found at home and abroad so named as “Hubei light sense of nuclear sterile rice.” The sterile material can self-propagate under short-day irradiation and cross-pollinate under long-day sunshine. Generally, all japonica rice varieties can be used as crossbreeding parents, and the cross-fertility generation is normal, which facilitates the extensive screening of strong heterosis cross combinations. In addition, the material can also be used as a tool for hybrid rice breeding.
