用遗传均差建立春小麦株高基因型图谱

Using the genetic average deviation to establish the genotype map of the spring wheat plant height

遗传均差可以用来表示不同春小麦亲本基因型株高间相对遗传变异的大小,表示不同基因型间的遗传距离.采用立体解析几何的方法,建立春小麦亲本基因型株高的基因型图谱.不同数量性状分别建立不同的基因型图谱.基因型图谱可以预测亲本间遗传均差的大小,基因型图谱的建立为数字化种质资源库的建立提供帮助,能提高育种效率.

The genetic average deviation was used to express the size and the distance of the genetic variation of the spring wheat plant height among different genotypes. With the method of solid analytic geometry, the genotype map was made. The different quantitative characters established the different genotype maps that predicted the size of the genetic average deviation of the different parents.
