亲本选配是任何一项育种工作的重要环节。杂交小麦育种是利用杂交 F_1,亲本选配愈显重要。遗传学研究种、育种实践都证明,在一定范围内,双亲的遗传差异越大,后代的分离幅度就越广,从而获得优良后代的机会就越多;双亲的遗传差异越大,F_1的杂种优势就越大。所以,双亲遗传差异大小应作为亲本选配的重要依据。六十年代初,国外开始应用多元统计的方法研究亲本间遗传差异。1979年,国内有人提
Parent matching is an important part of any breeding effort. Hybrid wheat breeding is the use of hybrid F1, the parental matching is more important. Genetics research and breeding practice all prove that within a certain range, the greater the genetic difference between parents, the wider the separation of offspring, and thus the more opportunities for obtaining excellent offspring. The greater the genetic difference between parents, the higher the F1 hybrid The greater the advantage. Therefore, the parents of genetic differences in size should be used as an important basis for parental matching. In the early 1960s, foreign countries began to apply multivariate statistical methods to study the genetic differences among parents. In 1979, some people in China said
