Vernonia (Vernonia galamensis (Cass.) Less.) is a new potential industrial oil crop with high content of vernolic acid in the seed oil. Ethiopia is one of the few Vernonia rich African countries. Knowledge of the genetic structure of the crop is very important for its improvement and sustainable management. The present study was targeted to investigate genetic diversity and population structure of 60 Vernonia genotypes in Ethiopia representing 8 populations using ISSR markers. A wide range of genetic diversity indices were computed to determine the extents and patterns of genetic variation within the eight populations. All the used markers were highly informative with polymorphic information content ranging from 0.5 to 0.71 with overall mean of 0.51, indicating that they are useful genetic tools for genetic structure analyses. The within-populations Nei’s gene diversity.. View more»
