Abstract: he genetic relationship of 39 blackcurrant cultivars was analyzed by inter-simple sequence repeats(ISSR). The results showed that the total number of bands(A)amplified by 13 ISSR primers ranged from 3 to 11,the average was 6.77,the mean percentage of polymorphic band(P)was 64.37%. Cluster analysis showed that 39 blackcurrant cultivars were divided into 5 groups at 0.8496 level of similarity coefficient. Cultivars in the groupⅠcame from 8 origin countries. It indicated that there was larger gene flow between countries.‘Ben Lomond’and‘Kantata’were farther with other blackcurrant cultivars in genetic distances. Both cultivars have high agronomic and fruit quality traits.‘Ben Lomond’and‘Kantata’will be good cultivars in the future breeding programme.
