一、配合力的意义及其应用获得杂种优势首先必须选择配合力良好的亲本。一般选择亲本常用测交的方法。亲本品种或品系较少时常用轮交法测定。设亲本数=n,则轮交组合数=n(n-1)/2。亲本品种或品系数较多时常用顶交法测定,顶交组合数=n-1。用这两种方法可以根据FI的表现选择亲本品种或品系,若在此基础上进一步应用基因效应的原理和生物统计
First, the significance of combining power and its application To get heterosis must first choose a good parent. Generally choose the method of measuring the cross commonly used by parents. The parent variety or line less frequently used method of rotation determination. Suppose the number of parents = n, then the number of turn combinations = n (n-1) / 2. The parental variety or product coefficient is often determined by the top cross method, the top cross combination number = n-1. Use these two methods to select the parental strain or line based on the FI’s performance, based on which the principle of gene effect and biometric
