SSR分子标记鉴定小豆F_1真假杂种

Identification of F_1 hybrid in adzuki bean(Vigna angularis)by SSR markers

SSR分子标记以其含量丰富、多态性高、共显性等优点,被广泛应用于多种作物F1代的真假杂种和种子纯度的鉴定。本文对43个杂交组合的123个小豆F1代材料,利用亲本多态性SSR标记,鉴定出真杂种66个,SSR标记可以有效地应用于小豆杂交F1代真假杂种鉴定。

SSR molecular markers are widely used to identify the hybrid in F1 generation and seed purity because of their abun- dance, high polymorphism and co-dominance. In this investigation 123 accessions of F1 from 43 cross combinations of adzuki bean were identified by polymorphie SSR molecular markers. 66 of them were distinguished true hybrids. SSR molecular mark- ers can be effectively used to screen F1 hybrid in adzuki bean true or false.
