Abstract

A new breeding technique is demonstrated using gynogenesis and sex-reversal. The essence of this method is an adequate alternation of gynogenesis and sibmating with a maximal increase in the coefficient of inbreeding. The rate of this increase considerably exceeds that characteristic of sibmating. The change in the coefficient of inbreeding (F) and in the degree of genotypic identity (I) were determined in the carp in which 9 recombination probabilities are known. In the GS system the value of F exceeds 0.9 in the fifth generation, increasing above 0.99 while in the 12th generation.

摘要

一种新的育种技术,使用雌核发育和性反转来进行展示。该方法的本质是充分交替雌核发育和近亲交配,使近交系数最大化增加。这种增加的速度大大超过了近亲交配的特征。在鲤鱼中确定了近交系数(F)和基因型一致性(I)的变化,其中已知 9 个重组概率。在 GS 系统中,第五代的 F 值超过 0.9,在第 12 代时增加到 0.99 以上。
