Understanding genetic diversity and phylogenetic relationships is useful for plant breeding. In this study, we assessed the genetic diversity in a panel of 84 accessions of kenaf from 26 countries using SRAP and ISSR markers. The kenaf accessions could be divided into L1 (60 cultivated varieties) and L2 (24 wild accessions) at the level of 0.145 genetic dissimilarity coefficient by UPGMA. The L₂ group was further divided into two subgroups (16 relative-wide and 9 origin wide accessions) at the level of 0.207 genetic dissimilarity. Out of the 9 wild accessions in the L₂ group, 6 were from Tanzania and the remaining 3 lines were from Kenya. These results suggest that the center of origin for kenaf might be Tanzania and Kenya.
