| 摘 要： | 以苹果梨为中心亲本的7个杂交组合做试材,对228株杂种后代的童期和主要果实经济性状做调查分析,研究苹果梨杂种后代亲本性状遗传倾向。结果表明:苹果梨杂种后代童期长短是由多基因控制的数量性状,后代结果年龄广泛分离。成熟期均以晚熟为主,早中熟较少。果实大小受环境因素和非加性效应影响较大,后代平均果重小于亲中值。果实形状广泛的分离,但以圆形居多。

| Abstract: | Took seven hybrids of apple-pear-centered parents as test material,analysed children's stage of the hybrid offspring of the 228 plants and the main fruit economic characters,studied parental traits genetic predisposition on apple-pear hybrid offspring.The results showed that apple-pear hybrid offspring children's stage duration was controlled by the number of multi-gene traits,the fruit age of offspring separated widely.Maturity stage were the main late-maturing,less early and middle maturing.Fruit size was... |
