Through 10 screened primers selected 18 species of rice material for PCR amplification. 144 bands with distinct and good repeat ability were amplified, which was 138 polymorphic bands and the polymorphic rate was up to 95.8%. Applications and combinations of primers 808,809,810, 816 and their combination won ISSR features with each species could effectively distinguish all the tested materials and establish their ISSR finger-print. Statistics 10 ISSR primers tag information and calculating the 18 samples of rice genetic similarity, the clustering analysis showed that rice samples tested geneti...
