水稻杂种优势利用研究,首先由美国Jones报导(1926)。其后,T.T.Chans等(1973)、Davis和Rutger(1976)、Virmani等(1981)、Virmani和Edwards(1983)评述了水稻各别农艺性状杂种优势的存在。印度Richharia(1962)、Swamin-athen等(1972),中国袁隆平(1966)、美国Sta-nsel和(Craigmiles(1966)、Craigmiles等 (1968)、Carnahan等(1972),日本新城长有、小村(1966)和国际水稻研究所的Athwal和Virma-ni(1972)等均曾提出培育F_1水稻杂种以大规模利用杂种优势的意见。但除我国继续其努力并获得成功外。其他大多数研究者都因预料到的制种困难而中断了研究。 随着杂交水稻在中国的发展,国际水稻所于1979年恢复了杂交水稻的研究。杂稻研宪纳入国家水稻改良方案的有印度、印尼、日本、美国、巴家,墨西哥、越南以及南朝鲜地区。此外,还有私营的美国园环和菲律宾卡尔吉耳两家种子公司,引进中国的杂稻进行试验评价和制种技术开发,目前,关于杂种优势利用的研究在世界上仍方兴未艾,研究的内容十分广泛。1986年10月5~10日,
Rice heterosis utilization research, first reported by the United States Jones (1926). Subsequently T. T. Chans et al. (1973), Davis and Rutger (1976), Virmani et al. (1981), Virmani and Edwards (1983) reviewed the existence of heterosis in agronomic traits of rice. India’s Richharia (1962), Swamin-athen et al. (1972), China’s Yuan Longping (1966), the United States Sta-nsel and Craigmiles (1966), Craigmiles et al. (1968), Carnahan et al. 1966) and the International Rice Research Institute (AWI), Athwal and Virma-ni (1972), all raised the suggestion of f1 hybrid rice for large-scale use of heterosis, except that our country continued its efforts and succeeded. Most of the other researchers Due to the expected difficulties in seed production, the study was discontinued.With the development of hybrid rice in China, IITR resumed research on hybrid rice in 1979. Rice research into the National Rice Improvement Program Kenyan, Indonesia, Japan , The United States, Pakistan, Mexico, Vietnam and South Korea. In addition, there are also private parks in the United States and the two seed companies in the Philippines, Calgary, to introduce China’s hybrid rice for experimental evaluation and seed production technology development. At present, The study on the utilization of heterosis is still in the ascendant in the world, and the content of the research is very extensive. From October 5 to October 10, 1986,
