Title: Genetic variation and seed transfer guidelines for lodgepole pine in central Oregon.

Author: Sorensen, Frank C.;

Date: 1992

Source: Res. Pap. PNW-RP-453. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 30 p

Publication Series: Research Paper (RP)

Description: Cones were collected from 272 trees at 189 locations uniformly distributed over the east slopes of the Oregon Cascade Range and Warner Mountains. Variation in seed and seedling traits was related to (1) seed source latitude, distance from the Cascade crest, elevation, slope, and aspect in multiple regression analyses; and (2) seed zone and elevation band in classification analyses. Provisional seed transfer guidelines are presented. These include a regression equation for guiding seed transfer and estimating transfer risk, and a new outline of fixed seed zones.

Keywords: Pinus contorta var. murrayana, lodgepole pine, geographic variation, seed transfer, breeding zones
