    Abstract Genetic diversity and relatedness of 17 water primrose (Ludwigia hyssopifolia) accessions in Thailand were estimated using morphological characters and random amplified polymorphic DNA (RAPD) markers. Eight morphological characters were diverse among the accessions. However, some accessions could not be distinguished from one another based on these morphological characters alone. Unweighted pair-group arithmetic average (UPGMA) analysis of these characters separated these 17 accessions into 2 major clusters. Among the 5 RAPD primers used, a total of 68 fragments (150 to 2000 bp) were amplified, showing a polymorphism percentage of 80%. The polymorphic information content (PIC) among accessions… More >
