大豆的遗传,一般分为质量性状遗传和数量性状遗传两大类。一、大豆质量性状遗传大豆质量性状遗传,是受少数基因控制的。如抗病性、花色(Ww)、毛色(Tt)、种皮色、结荚习性有限(dt_1 dt_2、亚有限Dt_1Dt_2、无限Dt_1 dt_2)、叶形(宽叶Ln、尖叶ln、中间型Lnln)等性状,这些性状为简单遗传。抗病性:(1)细菌性斑疹病抗病性受隐性基因rxP控制。
Soybean genetic, generally divided into qualitative traits of genetic and quantitative traits of genetic two categories. First, the quality of soybean Genetic quality of soybean genetic traits, is controlled by a few genes. Such as disease resistance, Ww, Tt, seed coat color, limited pod habit (dt_1 dt_2, subdominant Dt_1Dt_2, infinite Dt_1 dt_2), leaf shape (broad leaf Ln, sharp leaf ln, intermediate Lnln ) And other traits, these traits are simple inheritance. Disease resistance: (1) Bacterial rash disease resistance by the recessive gene rxP control.
