| Abstract: | The genetic diversities of 25 soybean varieties were studied by ISSR markers,9 polymorphic primers were selected from 28 ISSR primers,65 bands were amplified with 9 primers,they contained 58 polymorphic bands and their polymorphism percentage was 89.23%;Shannon's index evaluation indicted that average Shannon's index was 0.4604 and the numbers of effective alleles were 1.5139;the genetic similarity coefficient among the 25 varieties ranged from 0.4462 to 0.8923,and the average GS was 0.6692;cluster analysis... |
