利用湖北光周期敏感核不育水稻(HPGMR)的育性转换特性于两系杂交稻育种,是我国首创的一项新的水稻育种技术。W6154S、N5047S等一批籼、粳型核不育系的育成,标志着我国两系杂交稻育种技术的成熟。由湖北省农科院、湖南杂交水稻研究中心和广东农科院等单位同期配制的W6154S×特青2号,是我国两系杂交稻育种的一项重要成果。1989～1990年在鄂、湘、粤、皖、川、黔等省试验试种,表现比汕优63早熟、增产、抗白叶枯病和稻瘟病。1990年在湖北武昌、
Utilizing the fertility-switching characteristics of photoperiod-sensitive genic male-sterile rice (HPGMR) in two-line hybrid rice breeding in China, it is a new rice breeding technology initiated by our country. W6154S, N5047S and a number of indica, Japonica type sterile line breeding, marking the maturity of two-line hybrid rice breeding technology in China. W6154S × Teqing No.2 prepared by Hubei Provincial Academy of Agricultural Sciences, Hunan Hybrid Rice Research Center and Guangdong Academy of Agricultural Sciences was an important result of two-line hybrid rice breeding in China. In 1989 ~ 1990 in Hubei, Hunan, Guangdong, Anhui, Sichuan, Guizhou and other provinces pilot planting, performance than the Shanyou 63 precocious, yield, bacterial blight and blast resistance. 1990 in Wuchang, Hubei,
