Abstract

Amplified fragment length polymorphism (AFLP) and random amplified polymorphic DNA (RAPD) markers were used to provide estimates of the comparative genetic variation within and among populations of various Guizotia taxa with the goal of conserving and utilizing their genetic diversity. The percentage of polymorphic loci (PS) ranged from 28.5%-90% (AFLP) and 85.6%-99.6% (RAPD). The overall gene diversity estimate ((K) over bar (T)) has shown slight variation among taxa ranging from 0.32-0.37 (AFLP) and from 0.22 to 0.28 (RAPD). The within population diversity of "Chelelu'' and "Ketcha'' was found to be unexpectedly high. Both parameters used to estimate population differentiation (G(ST) and F-ST) revealed the highest population differentiation in G. zavattarii followed by G. arborescens. Genetic variation among populations within a taxon was highly significant for all the five taxa as revealed by AMOVA (P
