North America Pulse Improvement Association Biennial Meeting. p. 11. Technical Abstract: Lentil (Lens culinaris) is an important food legume that can provide significant amounts of dietary minerals and other essential nutrients to humans. To understand the nutritional diversity that exists within this species, we measured seed mineral and protein concentrations in 350 diverse accessions of the lentil single-plant derived core collection that is maintained by USDA. Plants were grown to maturity in a greenhouse using a soil mix and were irrigated daily with a complete nutrient solution. At maturity, all seeds collected from six plants per accession were combined, dried at 70 C, and finely ground to homogenize the bulk sample prior to further analysis. Ranges of seed mineral concentrations and protein percentages, along with correlations between traits, will be presented. Results will focus on Ca, Mg, K, P, Fe, Mn, Zn, Cu, and total protein. Data for individual accessions will be available in the USDA-ARS Germplasm Resource Information Network (GRIN) database, where it can be accessed by breeders and other scientists.
