摘要: 利用SSR分子标记技术对热研二号油绿苦瓜进行杂交种纯度检测技术研究。研究结果表明,5对SSR标记在热研二号亲本间表现明显的多态性,其中4对为共显性标记,1对为显性标记。为确保鉴定结果的准确性和可靠性,利用4对共显性的SSR标记对热研二号进行纯度鉴定,杂交种纯度为98.82%,与田间形态学鉴定结果完全一致。该研究表明利用SSR标记对热研二号油绿苦瓜进行纯度鉴定是切实可行的。

Abstract: The purity identification of Reyan No.2 was performed by using SSR marker technique. The results showed that 5 SSR markers were polymorphic between the parents of Reyan No.2, among which 4 were co-dominant markers, one was dominant marker. To ensure the accuracy and reliability, 4 co-dominant SSR markers were used for purity identification of Reyan No.2. The hybrid purity was 98.82%, which was completely consistent with field identification. It is feasible to conduct purity identification of Reyan No.2 using SSR markers.
