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。
The main economic traits of 11 hybrid combinations obtained from reciprocal crosses of pear and 64 hybrid seedlings were investigated. The results showed that: the small fruit type of pear had higher genetic ability, the population genetic level was 53.9% The genetic variation of soluble solid content in the fruit was super-progeny. The hybrids generally tended to be premature. The fruit flushing quality was 35.5%, and it was feasible to cultivate the red pear with fragrant pear. The hybridization shows that the use of wild pear cross-breeding is promising.
