中文百科

杂交水稻

杂交水稻,其主要思想是利用水稻的雄性不育来实现水稻的杂交。

1917年日本学者发现了野生水稻雄性不育。美国农学家琼斯于1926年提出水稻具有杂种优势理论。二战后世界各国科学家进行了长期的努力,提出了多种基于雄性不育来实现水稻杂交技术路线,著名的有希尔斯(Sears,E.R.,1943~1947)的“三系法”技术路线设计、爱德华生(Edwardson,J.R.,1956)的“二系法”以及日本科学家新城长友的“三系法”育种方案。首次成功的水稻杂交是由美国人Henry Beachell在1963年于印度尼西亚完成的。并由此获得1996年的世界粮食奖。1968年,日本科学家新城长友经过多年努力提出了一系列诸如赶粉等等杂交水稻育种新方法,首次成功实现了基于“三系法”配套育种。但是无论是Henry Beachell还是新城长友,其方案都存在着某些缺陷(不能稳产),无法进行大规模的推广,使得水稻杂交停留在实验室阶段,未能完成杂交水稻的产业化。

Hybrid rice 杂交水稻

Hybrid rice is any genealogy of rice produced by crossbreeding different kinds of rice. As with other types of hybrids, hybrid rice typically displays heterosis (or hybrid vigor) such that when it is grown under the same conditions as comparable high-yielding inbred rice varieties it can produce up to 30% more rice. High-yield crops, like hybrid rice, are one of the most important tools for combating world food crises.
