近年来,人们在担心粮食供需平衡的同时,从营养观点出发希望用谷类蛋白质育种来改善粮食的数量和质量.在玉米和大麦中,发现了高赖氨酸遗传基因源,并努力进行高产育种.日本四国农试场经十年时间,已成功地把高赖氨酸、高蛋白质的遗传特性导入了裸大麦的经济品种.至于小麦,美国布拉斯州大学的Johnson等曾进行了国际冬小麦联合试验,对 In recent years, people have been concerned about the balance between supply and demand of food and from the viewpoint of nutrition, they hope to improve the quantity and quality of grain by using cereal protein breeding. In maize and barley, high-lysine genetic resources have been found and breeding for high-yielding breeding Over the past ten years, Japan’s Shikoku farm experimentation has successfully introduced the genetic characteristics of high-lysine and high-protein into the economic varieties of naked barley. As for wheat, Johnson et al. Test, right
