[ Methods ] On this optimal ISSR amplification system, 16 primers were screened with good polymorphism, and the DNA was used to amplify the 20 plant samples. [ R^ults] The 16 primers produced 225 loci, of which 170 were polymorphic, and the polymorphic loci percentage was up to 75.56%. The genetic similarity coefficients between the 20 vari- eties ranged from 0. 577 8 to 0.951 1, which were calculated by POPGENE32. The 20 varieties by UPMGA analysis could be clustered into 2 groups, the first of which included Baiyangdian red lotus and Donggua lotus, and other varieties was included in the second group. [ Conchmions] ISSR molecular markers could be effectively used in genetic diversity and fingerprint analysis for different lotus varieties.展开更多
