Ｈｓ－３ 是采用系谱育种和花药培养相结合育成的两用不育系．其光敏特性明显，育性转换的临界光长较短（＜ １２．５ ｈ），不育起点温度低（＜ ２３ ℃），不育性稳定，不育期长（≥６５ ｄ），可繁性好．籼粳分类表明Ｈｓ－３ 为籼型．Ｈｓ－３ 生育期具有一定感光性，在福州３～６ 月份播种期（ｘ）与抽穗日期（ｙ）的回归关系为ｙ ＝ １０８ －０．４ｘ（ｒ＝ ０．９８）．Ｈｓ－３ 异交率高，配合力强，已选配的两系杂交稻新组合金两优３６，产量优势明显．１９９８ 年参加福建省中、晚稻区试，产量分别列参试组合的第１、第２位．
Hs-3 is a dual-use sterile line developed by a combination of pedigree breeding and anther culture. Its light-sensitive characteristics are obvious, the critical light length of fertility conversion is short (<12.5 h), the starting temperature of low sterility (<23 ℃), sterility stability, long sterile period (≥65 d) Good sex. Indica-japonica classification indicates that Hs-3 is indica. Hs-3 had a certain sensitivity during the growth stage. The regression relationship between sowing date (x) and heading date (y) from March to June in Fuzhou was y = 108 -0.4x (r = 0.98). Hs-3 outcrossing rate is high and its combining ability is strong. The new two-line hybrid rice combination Jinliangyou 36 has obvious yield superiority. In 1998 to participate in Fujian Province, late rice area test, the output column were listed in the first combination of the first two.
