Adaptive Genetic Variation of Broadleaf Lupine (Lupinus and latifolius) and Implications For Seed Transfer

Broadleaf lupine, (Lupinus latifolius) is a common native legume with potential utility for erosion control. The purpose of this study is to gain insight into species germination and growth and to establish seed transfer guidelines by estimating patterns of genetic variation and relating these patterns to environmental gradients. Seed samples from 83 populations of lupine were collected on the Mt. Hood National Forest, sown in the greenhouse, and outplanted into two replicate garden plots at two locations. Physical and phenological data were recorded for each seedling. Overall germination was 74% with 95% survival of outplanted individuals. Seedlings established extensive root systems and average plant height at 4.5 months was 27 cm. We found genetic variation for almost all traits examined and much of this variation is related to seed source, however patterns are complex and neither clinical nor classification models are completely satisfactory in explaining the variability among sources.
