回顾我国的水稻育种历史,已有两次重大突破,第一次是60年代初期矮化育种的成功,把水稻产量提高了20%—30%;第二次是70年代中期杂交水稻的研究成功,又使水稻产量增长了20%左右,为我国粮食生产作出巨大贡献。目前随着国民经济的发展和物质生活水平不断提高,人们在解决温饱问题后.对稻米品质提出了更高的要求,特别是早

There have been two major breakthroughs in reviewing the history of rice breeding in our country. The first was the success of dwarf breeding in the early 1960s, which increased the yield of rice by 20-30%. The second was the successful study of hybrid rice in the mid-1970s In turn, the output of rice increased by about 20%, making great contributions to the grain production in our country. At present, with the development of the national economy and the continuous improvement of material living standards, people have put forward higher requirements on the quality of rice after solving the problem of food and clothing. In particular,
