  • Title: Genetic diversity of kenaf (Hibiscus cannabinus) evaluated by inter-simple sequence repeat (ISSR).
    Author: Zhang L, Li A, Wang X, Xu J, Zhang G, Su J, Qi J, Guan C.
    Journal: Biochem Genet; 2013 Oct; 51(9-10):800-10. PubMed ID: 23794008.
    Abstract:
    Understanding genetic diversity is very useful for scientific utilization for breeding. In this study, we estimated the genetic distances in a panel of 84 kenaf accessions collected from 26 countries and regions using ISSR markers. The results of UPGMA analysis showed that kenaf germplasm had abundant genetic variation, with genetic dissimilarity coefficients ranging from 0.01 to 0.62. The in-group dissimilarity coefficient (0.29) was observed in 84 kenaf accessions, and all the accessions could be divided into three groups: cultivars (L1-1), relatively wild species (L1-2 and L1-3), and wild species (the others). Further in-group analysis in group L1-1 (0.19) revealed that the kenaf cultivars could be divided into five subgroups with distinct regional characteristics. It is imperative that genes be exchanged among all kinds of tested varieties from different origins. The results provide a useful basis for kenaf germplasm research and breeding.
