杂交育种能否达到预期效果,很大程度取决于亲本的选择。亲本的某些性状能否遗传及其遗传能力的强弱,常因不同的品种、组合而异。为了在今后的育种工作中正确选配亲本,提高育种效率,我们对酥梨、猪嘴梨、二宫白等多个优良亲本杂种后代的遗传倾向进行了观察。本文着重分析了酥梨与苹 Hybrid breeding can achieve the desired effect, largely dependent on the choice of parents. Whether some of the traits of the parents can inherit and the strength of their genetic ability often varies with different breeds and combinations. In order to correctly select the parents and improve the breeding efficiency in breeding work in the future, we observed the genetic predisposition of many fine parental offspring such as the pear, pig mouth pear, Ninomiya white. This article focuses on the analysis of pear and apple
