培育超高产水稻是近些年来国内外水稻研究的重点、热点和难点,日本和国际水稻研究所先后于1981年和1989年实施水稻超高产育种和超级稻(后改称“新株型”稻)育种计划,但因其难度大和技术路线问题,至今都尚未实现。1996年,我国农业部设立“中国超级稻育种”项目,计划分两期,以中稻为例,第一、二期目标分别是:到2000年、2005年育成亩产700公斤和800公斤的水稻品种。 Breeding super-high-yielding rice has been the focus, hotspot and difficulty of rice research at home and abroad in recent years. Japan and the International Rice Research Institute successively implemented the breeding of super-high yield rice and super rice (later renamed as “new plant type”) in 1981 and 1989 respectively Plan, but because of its difficulty and technical route issues, so far have not yet been achieved. In 1996, China’s Ministry of Agriculture set up the project of “China’s super-rice breeding” with two phases planned. Take mid-rice as an example. The objectives of the first and second phases are as follows: By 2000 and 2005, fertile rice of 700 kg per mu and 800 kg per mu will be bred Variety.
