晚红珠樱桃实生苗果实性状遗传研究

Study on the Inheritance of Fruit Characters of ‘Wanhongzhu ’ Sweet Cherry Seedlings

以154株晚红珠樱桃实生苗为试材,通过调查后代果实经济性状,对其遗传特性进行研究。结果表明,晚红珠樱桃实生苗果皮颜色为质量性状,红色∶黄红色为2.85 ∶1;单果重和可溶性固形物含量为数量性状,符合连续变异的遗传特点,变异范围较大,既能出现远小于亲本值的单株,也有大于亲本值的单株;果实的成熟期受亲本影响较大,61%表现亲本类型,26%倾向于亲本,13%出现超亲遗传。

With 154 seedlings of ‘Wanhongzhu’ sweet cherry as material,some fruit characters were investigated to study genetic tendency. The results showed that the fruit color of ‘Wanhongzhu’ sweet cherry seedings was qualitative character, the ratio of red and yellow-red color was 2.85 ∶1. Fruit weight and soluble solid content were quantitative character and controlled by polygenes. The two genetic traits were continuous variation, and the range of variation were wide, there were seeding that the weight and soluble solid content less than or greater than the female parent average value.The fruit mature period were affected obviously by female parent, 61% was female parent type, 26% was tend to parent type, 13% was superiority over parent type.
