| 摘 要： | 对香梨正反交获得的１１个组合、６４株杂种实生树的果实主要经济性状进行调查，结果表明：香梨的小果型遗传能力较强，群体遗传水平为５３．９％，果心趋中遗传；果实可溶性固形物含量超亲遗传；杂种普遍倾向早熟；果面红晕为质量性状，杂种红晕株率达３５．５％，用香梨培育红皮梨切实可行；香梨与杜梨的杂交表明利用野生梨开展种间杂交育种很有希望。

| Abstract: | Main fruit economic characters were investigated in 11 cross combinations with Xiangli as one of parents.The results were as follows:Xiangli had high heritability of small fruit size with popularity GCA 53.9%. Fruit core was inclined to mediumsize.Soluble solid content of hybrid progenies was superior to their parents.Hybrid progenies tended to earlymature.High red blush rate (35.5%) convealed the possibility of crossbreeding to develop redpeal pear with Xiangli as one of parents.The results indicated the feasibility of interspecific crossing using wild pear species,too. |
