蛋白质含量是决定饲料品质的有价值性状之一。在解决这个问题上豆科作物起主要作用。特别是苜蓿具有更重要的作用。 提高粗蛋白质含量的育种效果取决于存在的能够把这种性状比较容易地遗传给其它品种和类型并与这种性状一起不能表现出来任何一个很难或者不能分开的不良特性的遗传材料。 高蛋白类型诊断的间接方法可以有助于加快提高蛋白质含量育种。为此广泛应用了 Protein content is one of the valuable traits that determine feed quality. Legume crops play a major role in solving this problem. In particular, alfalfa has a more important role. The breeding effect of increasing the crude protein content depends on the genetic material present which can easily convey the trait to other breeds and types and can not exhibit any one difficult or inseparable trait together with such trait. Indirect methods of high-protein type diagnosis can help speed up the breeding of proteins with increased protein content. Widely used for this purpose
