Many minor legume crops have a niche to fill in the USA, given the benefits of crop rotation, adaptation to specific soils and environments, and markets. Myths about a lack of genetic diversity, poor cold tolerance, and other agronomic traits have been perpetuated by some in white lupin (Lupinus albus L.), which has a number of potential uses. In this paper, we specifically discuss cold tolerance, phenological development, environmental and geographical possibilities and limitations, and genetic resources for the Southeast. Cold tolerance is not a limitation in the new breeding material if proper management practices are followed. One Auburn variety coming up for PVP release was barely and only transiently affected by the third and final freeze of the spring 2005. In the southernmost areas of the Southeast, reproductive growth is limited to less than 2 months because spring temperatures rise too quickly above the average threshold temperature of 20^oC; this results in poor grain yield due to limited branch development. At higher elevations and northwest of Virginia, in areas with averages which remain ≤ -2^oC for most of the winter, vegetative development during the rosette stage would be limited, resulting in poor biomass and grain production. This could also encourage early flowering and freeze damage/killing after the vernalization requirements are met. Tremendous genetic diversity is available in white lupin, although some germplasm may need to be obtained from the Australian collection, and secondary centers of origin which haven't been collected from extensively. Over a 15 year period, grain yields have increased from 2250 kg ha^-1 to 3250 kg ha^-1 with advanced material in trials at E.V. Smith Research Center in central Alabama. Earlier flowering dates have contributed to this increase; further increases may require an overall biomass increase, similar to that recommended for lentils in the Pacific Northwest.
