过去以稻麦为中心的谷类作物的育种,把重点放在提高丰产性上,似有忽视改善营养价值的倾向。通过品种改良获得比过去更稳定的高产而商品价值高的品种,固然是重要的。可是,忘记通过营养价值的改善,来为维持和延续人类的生命而提高必要营养的总量,也不成吧。不消说,谷类是重要的淀粉供给源,同时,作为蛋白质供给源,总希望也是高产、优质的。虽说不及大豆,稻米约含6～9%,麦约含10～13%的蛋白质,但据 Parpia(1970)估计,世界谷类蛋白生产量达11300万吨,为牛乳、肉、蛋、鱼等动物蛋白的总和3900万吨的3
In the past, rice-wheat-based cereal breeding, which focused on improving productivity, seemed to ignore the propensity to improve nutritional value. Of course, it is important to obtain more stable and high-yielding varieties of higher commodity value through variety improvement. However, forgetting to improve the nutritional value through the maintenance and continuation of human life and increase the total amount of necessary nutrition, not a bar. Needless to say, cereal is an important source of starch supply, and at the same time, it is always hopeful, high-yielding and high-quality as a protein source. Although less than soybeans, rice contains about 6 to 9% and Mai about 10 to 13% protein, but according to Parpia (1970) it is estimated that the world cereal protein production amounts to 113 million tons for animals such as milk, meat, eggs and fish The sum of proteins is 39 million tons of 3
