Genetic diversity was analysed in 52 Argentinian populations of Avena barbata, a tetraploid grass introduced in America from Spain during the colonization period. Nine isozyme systems were studied and 14 loci identified, five of which were polymorphic. Cluster analysis based on Hedrick’s index revealed a high similarity among populations. The total diversity (Pt) in the 52 populations was 0.144, the mean diversity (Ps) was 0.04, while between population diversity (Dst) was 0.103. The resulting… Expand
