Genetic Diversity in Saccharum spontaneum L.Based on ISSR Markers
In order to analyze the genetic diversity of Chinese S.spontaneum L.,a toatal of 52 S.spontaneum L.was used and ISSR markers were apllied.With 22 ISSR primers,127 loci were detected among which 121 were polymorphic,indicating considerable genetic variations at the species level.The genetic similarity among all accessions was ranged from 0.60 to 0.91.The 52 S.spontaneum L.were clustered into four groups by UPGMA when GSC was 0.72.The study indicated that ISSR produced high polymorphism on S.spontaneum L.and could be used in the study of the molecular evaluation and studies of genetic diversity of the S.spontaneum L.germplasm.
