[ Method ] Out of total 245 pairs of primers, 18 were selected for SSR amplification of 360 V. amurensis experimental materials. [Result] The number of bands amplified by each primer ranged from 4 to 13 with a mean of 9.44. The length of bands ranged from 150 to 1 000 bp, concentrated at 200 -750 bp. The 18 pairs of primers amplified 170 bands totally, of which 167 bands were polymorphic with a polymorphism ratio of 98.2%. The Shannon＇s diversity index （I） is 1. 778 051. With the SSR-PCR am- plification of 360 V. amurensis varieties （ strains）, 5 specific bands were amplified by certain primers in several varieties（strains） accounting for 2.95% of the total bands. [ Conclusion] SSR molecular marker technique was an efficient method to detect the genetic diversity of V. amurensis and thereby is an effective tool for pedigree analysis and variety identification of A. amurensis varieties（strains）.展开更多
