湖北省光周期敏感核不育水稻(HPGMR),系我省沔阳县沙湖原种场石明松同志首先发现选育的。他经过十多年的试验研究,初步认为其原始核不育水稻的特征特性已经基本稳定,它与籼、粳、糯稻杂交,具有较强的杂种优势。为了进一步掌握其基本特性,研究其利用价值,在生产中尽快发挥作用,从1983年起,作者对原始核不育水稻的育性作了初步观察,并应用于育种实践。现将其育性观察情况简略报道如下:
Photoperiod-Sensitive Genic Male Sterile Rice (HPGMR) in Hubei Province was first discovered by Comrade Shi Ming-song, the former species plant of Shahu in Leiyang County of Hubei Province. After more than ten years of experimental research, he initially thought that the characteristics of its original nuclear-sterile rice has basically stabilized. It hybrids with indica, japonica and glutinous rice and has strong heterosis. In order to further grasp its basic characteristics, to study the value of its use, play a role as soon as possible in production, from 1983 onwards, the author made a preliminary observation of the fertility of the original nuclear sterile rice, and applied to breeding practice. The fertility observation is now briefly reported as follows:
