20多年来,国内外农业科学家在改良稻米蛋白质含量方面做了大量的研究工作,然而由于环境条件的影响和遗传背景的限制,高蛋白含量的水稻品种生产上直接应用的则很少。随着生产水平和人民生活水平的不断提高,选育高产高蛋白水稻品种显得越来越重要。R.Rabon等认为,高产高蛋白水稻品种选育进展缓慢的一个重要原因是高蛋白基因与某些不良性状基因的紧密连锁,因此要获 For more than 20 years, domestic and foreign agricultural scientists have done a lot of research on improving the protein content of rice. However, due to the influence of environmental conditions and genetic background, there are few direct application of high protein content rice varieties. With the continuous improvement of production level and people’s living standard, it is more and more important to breed high-yield and high-protein rice varieties. R.Rabon so that high yield and high protein rice varieties breeding slow progress is an important reason for the high protein genes and some bad trait gene close linkage, so to be
