McKee, R. | Hyland, H.L. | Ritchey, G.E.
Selected strains of nonalkaloid blue, yellow, and white lupines have been included in experimental plantings in the United States. Good growth and yields have been attained with nonalkaloid selections of the yellow and blue species, but only comparatively low yields have been obtained with the white species. It has been determined that varieties cross within species so that it is necessary to keep nonalkaloid selections isolated from high-alkaloid plantings. The possible value of nonalkaloid lupines for livestock feed is suggested and experiments to determine their feeding value are being carried on by the Florida Agricultural Experiment Station. A quick method for determining the presence of alkaloid is described.
