摘要：
The genetic diversity of Dongxiang wild rice populations was evaluated by using 14 SSR primer pairs. Twelve of the primer pairs amplified polymorphic bands. A total of 70 polymorphic DNA bands were generated with average 5. 83 polymorphic bands per primer pair, indicating that the genetic diversity of Dongxiang wild rice was high. Cluster analysis showed that there were highly variant individuals within and among populations, while others were highly similar to each other. The within-population genetic distances were 0. 23 - 0.47, being smaller than 0.40 - 0.55 of among-population. Strict management must be taken for the preservation of Dongxiang wild rice.
