以南果梨为母本 F_1抗寒力较强,叶形有18.2%~34.3%为母本的卵圆形;叶缘有35.4%~54.4%为母本的刺芒状锯齿;叶脉与叶柄颜色不同程度的呈现母本的红色,两个组合分别为73.2%~64.9%,南果梨×象牙梨组合父本的影响为39.2%;叶大小多近似母本。F_1的果形以长圆形与圆球形为显性。品质遗传趋向于甜(39.1%~75.0%);汁多或极多;品质较好,南果×威宁大黄梨组合,品质上与极上的占50.0%,其余两个组合为15.4%与17.4%。香味遗传力弱。果重多趋于小果及中间类型。
South fruit pear female parent F_1 strong cold resistance, leaf shape 18.2% ~ 34.3% for the female parent oval; leaf margin 35.4% ~ 54.4% of the mother of the barbed miter serrated; veins and petiole color In different degrees, the maternal red showed a combination of 73.2% -64.9%, respectively, and the effect of Nanguo pear × Ivory pear combination was 39.2%. The leaf size was similar to that of the female parent. The shape of F_1 is oblong and spherical. The quality inheritance tended to be sweet (39.1% -75.0%); the juices were more or more; the quality was better; the ratio of south fruit × Weining rhubarb and pear was 50.0%, the other two were 15.4% and 17.4%. Herb genetic weakness. Fruit weight tends to be small fruit and the middle type.
