Abstract
Genetic diversity and species relationships among ten species of Utricularia were investigated using inter simple sequence repeat (ISSR) markers. Six primers generated 236 ISSR fragments across the ten species with an average of 39.3 fragments per primer. Utricularia longifolia presented the highest number of fragments whereas U. amethystina, U. humboldtii and U. uliginosa provided the least. The highest similarity was detected between U. alpina and U. longifolia among the species studied while the highest pairwise genetic distance was found between U. caerulea and U. longifolia. Principal coordinate analysis was conducted to view the clustering pattern of the taxa which revealed that U. alpina and U. longifolia clustered together whereas U. amethystina, U. bifida, U. caerulea, U. calycifida, U. humboldtii, U. praelonga, U. triflora and U. uliginosa formed another cluster.
