Abstract
Diploid, tetraploid, and hexaploid populations of Atriplex canescens (x=9) were examined for 18 isozyme systems. Of 24 interpretable loci, only one locus (Per1) was polymorphic. Another locus (Per2) showed a dosage effect. Genetic distance values, D, ranged from near 0 to 0.05, which are in the normal range for local species races. Results from clonal ramets gave identical results. The data and analyses support an essentially autopolyploid origin for the polyploid populations examined.
