RT Journal Article SR Electronic T1 Genetic variation in Broadleaf Lupine (Lupinus latifolius) on the Mt Hood National Forest and implications for seed collection and deployment JF Native Plants Journal JO NATIVE PLANTS JOURNAL FD University of Wisconsin Press SP 36 OP 48 DO 10.1353/npj.2005.0018 VO 6 IS 1 A1 David L Doede YR 2005 UL http://npj.uwpress.org/content/6/1/36.abstract AB 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.
