Genetic variation in broadleaf lupine (Lupinus latifolius) on the Mt. Hood National Forest and implications for seed collection and deployment

Abstract:

Analysis of a common-garden study of broadleaf lupine (Lupinus
latifolius Lindl. ex J.G.Agardh ssp. latifolius [Fabaceae]) indicates
that use of watershed delineations is better than use of plant
association series for determining seed zones on the Mt Hood
National Forest. Risk analysis further confirmed that only 4
seed zones are required, providing a reasonable compromise
between managing costs and maintaining local adaptation.
Overall, moderate amounts of genetic variation were found in
84 seed sources.Two principal components (PCs) summarized
58% of the variation in 24 measured traits, and variation in PC
scores was significantly correlated with topographic, geographic,
and climatic variables. Regression analyses showed that
these variables accounted for 47% of the variation in the first
PC and 34% of the variation in the second PC.
