A national germplasm collection and evaluation of two of the three recognised subspecies of Atriplex nummularia (Oldman Saltbush) i.e ssp. nummularia and ssp. spathulata is being undertaken.
Seed and plant specimens have been collected from populations of A. nummularia ssp. nummularia and spathulata from across their geographical range.
Herbarium voucher specimens from each location and fresh leaf specimens for DNA analysis have been collected and will be examined as part of a taxonomic review.
Depending on the results of subspecies and provenance trials it is proposed that a plant improvement program be undertaken to produce one or more fully commercial cultivars.
