湖北光敏核不育水稻(HPGMR)自发现以来,经过湖北及全国协作研究,近年已育成一大批籼粳型不育系和两系强优势组合而进入推广应用阶段。仅湖北、广西和湖南两系杂种种植面积即由1988年1000多亩到1989年的1.5万亩,1990年更有大幅度增长。但不同组合、产地间,种子纯度差异甚大,究竟是
Since its discovery, Hubei Photosensitive Genic Male Sterile Rice (HPGMR) has been bred in Hubei Province and the whole country. In recent years, a large number of indica-japonica CMS lines and two strong lines have been bred into the popularization and application stage. Only Hubei, Guangxi and Hunan acre planted acreage from 1000 mu in 1988 to 15000 mu in 1989, more substantial growth in 1990. However, different combinations, origin, great differences in seed purity, what is
