超级稻,这样一个超级吸引人的名称,承载着全世界水稻育种专家们的光荣与梦想。在超级稻诞生前,我国水稻发展史上,单产曾经出现过两次重大突破。第一次是始于20世纪50年代末60年代初的矮化育种,主要通过降低株高,使品种的耐肥抗倒性和收获指数大幅度提高。第二次是出现在20世纪70年代中期的杂种优势利用,使我国水稻平均亩产提高到400公斤以上,高产地区突破500公斤,达到世界先进水平。水稻单产的这两次重大突破,均给我国水稻生产带来革
Super Rice, a super-appealing name that carries the glories and dreams of rice breeders around the world. Before the birth of super rice, in the history of rice development in our country, there have been two major breakthroughs in yield. The first is a dwarfing breeding that began in the late 1950s and early 1960s. The reduction of plant height has led to a substantial increase in resistance to lodging and harvesting. The second is the use of heterosis that emerged in the mid-1970s, raising the average yield per mu of rice to more than 400 kg in our country and 500 kg in high-yield areas, reaching the world advanced level. These two major breakthroughs in rice yield have all brought leather to our rice production
