| 摘 要： | 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。

| Abstract: | SSR methods were applied to detect genetic diversity of 45 Tsai-tai germplasm from China, provided biological foundation for the utilization and seed breeding of the Tsai-tai germplasm. 124 bands were amplified with 63 SSR primers.The amplified DNA fragments size were 100~300bp. Similarity coefficients between 0.56 ~ 0.89. The results show there were abundant genetic diversity in the Tsai-tai germplasm of China. |
