红菜苔是我国独有的蔬菜资源,深受消费者喜爱。利用63对SSR引物检测来自全国的45份红菜苔种质资源的遗传多样性,63对引物扩增出124条带,平均每条引物扩增出近2条带,扩增产物片段大小都在150～300bp之间,相似系数在0.56～0.89之间。结果表明,红菜苔具有丰富的遗传多样性,本研究为菜苔资源的利用和育种提供了分子生物学依据。 Red moss is a unique vegetable resources in China, loved by consumers. 63 pairs of SSR primers were used to detect the genetic diversity of 45 Apocynaceae germplasms from China. 124 bands were amplified from 63 pairs of primers, with an average of nearly 2 bands per primer. Amplification products were Between 150 and 300bp, the similarity coefficient is between 0.56 and 0.89. The results showed that red ginseng was rich in genetic diversity. This study provided a molecular biological basis for the utilization and breeding of ginkgo resources.
