我国水稻育种技术发展历程回顾

回顾了我国水稻育种技术的发展历程。我国水稻育种技术成就:水稻的矮秆化形成产量首次飞跃,杂交水稻的成功选育促成产量进一步提升,超级稻育种技术则使产量上升到更高水平。目前,水稻育种技术的发展,除了重视产量的提高外,分子育种技术的发展则更加注重稻米品质、营养、抗病虫害、抗寒、耐热等方面潜力的挖掘。

Progress Review on Technology of Rice Breeding in China

This article reviewed the developmental history of rice breeding technology in our country.In the research progresses of rice breeding technology in China,the dwarfing of rice caused the first leap of rice yield,the successful breeding of hybrid rice led to the further rising of rice yield,and the technology of super rice breeding increased rice yield to a higher level.At present,along with the development of rice breeding technology,rice breeding especially rice molecular breeding pays more attentions to rice quality,rice nutrition,disease and insect pest resistance,cold resistance,heat tolerance of rice plants,besides the increase of rice yield.
