配合力是指亲本传给子代的相对能力.它分为一般配合力和特殊配合力两种.前者与累加性遗传效应相关联,而后者则与显性,超显性和上位性的遗传效应相关联.配合力的研究,在动植物的育种中日益显示出其重要牲.它产生于研究杂种优势的遗传原因及制定具有杂种优势的玉米杂交种选育过程中.其目的在于探讨选择材料配合力的鉴定方法,查明配合力变化原因和程度,制定配合力育种的有效方法和亲本选择方法等杂种优势的现实问题.
Combining ability refers to the relative ability of parents to pass on to offspring, which is divided into general combining ability and special combining ability, the former is related to cumulative genetic effect, while the latter is related to dominant, super dominant and epistatic heredity The study of combining ability has increasingly shown its important sacrifice in the breeding of plants and animals.It originated from the genetic reason of studying the heterosis and the breeding process of breeding hybrid corn with heterosis.The purpose is to explore the choice Material combining ability identification method to identify the reason and degree of combining ability to develop effective methods of combining force breeding and parent selection methods such as the practical advantages of heterosis.
