安徽省两系杂交水稻种子生产安全技术与应用研究(Ⅰ)——粳型光敏核不育系的育性研究

Safety Technology of Seed Production of Two-line Hybrid Rice and its Application in Anhui Province(Ⅰ) Study on the Fertility of Japonica PGMS Lines

198 7～ 2 0 0 1年对安徽省农科院水稻所育成的 70 0 1S、80 87S、3 5 0 2S、3 5 16S 4个粳型光敏核不育系进行了育性观察。研究结果表明 :4个粳型光敏核不育系在合肥历年稳定不育期为 8月 10日至 2 5日。同时根据多年应用实践 。

The fertility of 4 Japonica PGMS lines: 7001S, 8087S, 3502S and 3516S, which were bred by our group, had been studied from 1987 to 2001 in Hefei, Anhui. The results showed that the steadily completely sterile period of them was from the tenth to the twenty-fifth of August. Meanwhile, according to applying practice for many years, the 4 lines were assessed in this paper.
