苹果梨的育种价值

该文指出,苹果梨综合性状优良,是很好的梨育种种质资源;以苹果梨及其后代为亲本已选育出30余个新品种,大大丰富了梨种质资源;苹果梨的大果、耐贮、小果心、抗寒等优良性状在后代品种中有较强的表现;以苹果梨与多倍体品种杂交后代为多倍体的比率较高。并展望了苹果梨在今后育种中的主要研究方向。

Breeding Value of Pingguoli Pear

Pinguoli pear is a very good germplasm resource for pear breeding with the good comprehensive characters.More than30new varieties,bred by Pingguoli pear and its progencies as their parents,have enriched the pear germplasm resources greatly.The excellent characters such as big size,small core,good storage and good cold resistance have strong performance in pingguoli's progenies.The progenies of the crossing between pingguoli and polyploid variety have higher ratio of polyploidy.And the main research perspective of pingguoli pear in the future pear breeding has been expected.
