通过对1983～1995年香梨杂交育种的观察,研究香梨与砀山酥梨、鸭梨、苹果梨进行正反交获得的541株杂交后代的遗传倾向,结果表明,杂交后代果实形状、肉质遗传倾向于亲本,倾亲率分别为70.2%和85.2%,且果心较亲本的小。香梨作母本时果形、果心遗传传递力较作父本时强。杂交后代果实品质变劣,劣变率为97.4%,香梨作母本的后代较作父本的品质好。 Based on the observation of crossbreeding in pear during 1983-1995, the genetic tendency of 541 crossbreeds obtained from reciprocal crosses between Xiang pear, Dangshan pear, Yali pear and apple pear was studied. The results showed that the fruit shape and fleshy inheritance Tend to the parents, dumping rates were 70.2% and 85.2%, respectively, and the fruit of the parents than the small. Pear as a female parent when the fruit shape, fruit heart transmission power than the father of the strong. The fruit quality of hybrid progenies was worsened, the rate of deterioration was 97.4%. The offspring of pear as the female parent had better quality than the male parent.
