以双8-14s、105s 为光敏感核不育基因供体,以国内外不同类型的籼稻和粳稻品种为受体亲本,采用杂交、辐射及单株系谱选育方法选育出多种类型籼稻和粳稻光敏核不育系,籼型如8902s、8906s、8912s 和8920s 等,粳型有 WD_ls、M105-9s等.初步育成两系杂交中籼组合8902s/明恢63、8902s/明恢72、8906s/特青2号、8912s/明恢63等,两系晚粳组合 M10s-9s/反5-2等,以及两系亚种问组合8912s/轮回422、8902s/UG28、8902s/Varylava等,并已开始生产性试种.
With double 8-14s and 105s as photosensitive genic male sterility gene donors, different types of indica and japonica rice varieties at home and abroad were used as parental recipients. Breeding, radiation and single pedigree breeding methods were used to breed indica rice And indica type such as 8902s, 8906s, 8912s and 8920s, japonica type WD_ls, M105-9s, etc. Two-line indica hybrid rice 8902s / Minghui 63,8902s / Minghui 72 were initially bred, 8906s / Teqing 2, 8912s / Minghui 63, two lines of late japonica rice combination M10s-9s / anti-5-2, etc., as well as two lines of subspecies 8912s / reincarnation 422,8902s / UG28,8902s / Varylava, And has started productive test.
