Abstract

In order to facilitate the addition of a genetic component to conservation management plans for Georgia false indigo (Amorpha georgiana var. georgiana), a rare legume of the southeastern USA, 12 polymorphic microsatellite markers were developed. No gametic disequilibrium was detected among locus pairs, but observations for five of the loci significantly deviated from expected Hardy–Weinberg proportions. Cross-species testing was successful and demonstrated the utility of the majority of the markers in congeners Amorpha georgiana var. confusa and Amorpha herbacea. The results also suggested that A. georgiana var. confusa is tetraploid rather than diploid.
