title: Variation in Leaf Morphology and Agronomic Attributes of a Naturalized Population of Medicago polymorpha L. (Burr Medic) from New South Wales, Australia, and Relationships with Climate and Soil Characteristics
abstract: As one component of a study to improve Medicago spp. germplasm in eastern Australia, fifteen phenotypic and agronomic attributes were recorded for 4715 plants grown from the seed of 90 accessions of the widely naturalized pasture legume Medicago polymorpha from 90 sites in eight regions of inland New South Wales. The species expressed wide polymorphism. However, many leaflet attributes were associated with specific climate and soil characteristics, which varied from east to west across the colle
