我与水稻种子结缘40周年,在深化改革中,为当前攻关水稻早熟、优质、多抗、超高产育种理论与实践获得点滴体会。回顾建国以来,我国水稻育种产量第一次突破,是1956年高秆改矮秆,改良株型,育成的早、中、晚稻品种,只有10多年时间普及全国各地,增产大量粮食。第二次突破,是1973年杂交稻配套,改善株型,产量居世界领先地位,也只有10多年时间,到1988年推广1.63亿亩,占全国稻田面积三分之一,又增产了大量粮食。有人说:“今后是杂交稻的世界”。从当前看,杂交稻发展快;从长远考虑,常规稻很重要。大家知道,杂交稻的三系,都来源于常规稻,常规稻产量高,杂交稻产量更高。今年3月2日《中国农牧渔业报》报道的特青、中83—49和吉粳62一样,有
I am fortunate to have been fortunate to celebrate the 40th anniversary of rice seed breeding. In deepening the reform, I gained some experience in the current theory and practice of early maturity, high quality, multi-resistance and ultra-high yield breeding of rice. Recalling the founding of our country, the first breakthrough in rice breeding in China is the 1956 stalks and improved dwarf, plant type, bred early, middle and late rice varieties, only 10 years spread throughout the country, an increase of large quantities of food. The second breakthrough was the installation of hybrid rice in 1973 to improve its plant type and yield to a leading position in the world. It took only 10 years for it to popularize 163 million mu in 1988, accounting for one third of the total area of paddy fields in the country and a large amount of grain production . Someone said: “The future is the world of hybrid rice ”. From the current perspective, hybrid rice develops fast; in the long run, conventional rice is very important. As we all know, all three lines of hybrid rice come from conventional rice, with high yield of conventional rice and higher yield of hybrid rice. On March 2 this year, “China’s Agriculture, Animal Husbandry and Fisheries,” reported Teqing, 83-49 and Jijing 62, there
