大豆的亩产量很低,通过育种手段实现其产量的突破是值得研究和探索的。买现高产育种,首先应把良种良法的概念从品种推广阶段提前到育种的选择阶段,以高水肥条件选择产量突出的类型,稀擅可能是大豆高产的条件,因此,研究稀植高产的品种和稀植精细集约化管理相结合创造大豆高产的途径。第二是拓宽遗传基础,提高种质水平是大豆实现产量突破的基础。第三注意亲本选配和強调早 Soybean yield per mu is very low, it is worth to research and explore the breakthrough of yield through breeding. To buy high-yielding breeding, we should advance the concept of good-breeding good seed from the stage of promoting the variety to the selection stage of breeding, and select the type of yield with high water-fertilizer conditions, which may be the condition of high-yielding soybean. Therefore, And thinning intensive intensive management to create a high yield of soybean. The second is to broaden the genetic basis and improve germplasm level is the basis for soybean production breakthrough. The third attention to the parent matching and emphasis earlier
