改良玉米籽粒品质,特别是提高籽粒中有价值的蛋白质含量並改进其品质的育种,是重要的。过去用选种方法使玉米蛋白质含量得到了提高,但这主要是提高了对饲用玉米有点价值的醇溶蛋白部分,价值高的赖氨酸和色氨酸没有提高。 改进玉米全套蛋白质,尤其是提高特感缺乏的氨基酸——赖氨酸和色氨酸,是可能
It is important to improve maize grain quality, particularly breeding to increase valuable protein content in grain and improve its quality. In the past, the corn protein content was increased by the selection method, but this mainly increased the gliadin fraction which is of little value to the feed corn. The high value of lysine and tryptophan did not increase. It is possible to improve corn’s complete set of proteins, especially the amino acids Lys and tryptophan
