摘要: 利用SSR分子标记技术对热辣3号辣椒杂交种进行纯度鉴定。从85对SSR引物中筛选出10对引物在热辣3号亲本间表现明显的多态性,均为共显性标记。为了提高鉴定结果的准确性,选用位于辣椒不同染色体上的3对共显性标记对热辣3号辣椒进行纯度检测,种子纯度为99.49%。分子标记鉴定与表型鉴定比较分析表明,2种鉴定结果高度一致。研究结果表明,SSR分子标记可以用于热辣3号辣椒杂交种纯度的快速、准确检测。

Abstract: Establishing a rapid and stable seed purity identification technology system is the effective measure for controlling the pepper hybrid quality. The development of molecular marker techniques could provide an accurate and fast way for identifying the crops hybrid purity. In this study,SSR markers were applied to testing the purity of Rela No. 3. 10 pairs among 85 pairs of SSR primers showed significant polymorphisms between the parents of Rela No. 3. All of them were co-dominant markers. In order to improve the accuracy of identification results,three codominant SSR markers located on different chromosomes were selected for purity test of Rela No. 3. The seed purity was 99. 49%. Comparative analysis showed that the identification results of molecular markers and phenotypes were highly consistent. The study results indicated that SSR markers could be used for hybrid purity test of Rela No. 3, quickly and accurately.
