提高高粱籽粒的蛋白质含量,从而提高其营养价值,是品质育种的主攻方向.由于设备、资金和效率的限制,大规模进行蛋白质含量的分析仍较困难,并且所采用的测定方法又多有破坏性,因而选择多是寄希望于高代系,这在很大程度上限制了育种效率.1978年,Hiraiwa和Tanaka用“比重法”测试大豆的蛋白质和脂肪含量收到很好效果.最近Peterson等又提出了对小麦进行类似筛
Increasing the protein content of sorghum grain to increase its nutritional value is the main direction of quality breeding.Because of the limitations of equipment, capital and efficiency, it is still difficult to analyze the protein content on a large scale and the method of determination is more and more destructive Therefore, Hiraiwa and Tanaka tested the protein and fat content of soybeans very well with the “Gravimetric method” in 1978. Recently Peterson et al. Proposed a similar sieve for wheat
