Publication Series: Research Paper (RP)

Description: Provisional seed zones and breeding zones were developed for sugar pine (Pinus lambertiana Dougl.) in southwestern Oregon. Zones are based on a map of genetic variation patterns obtained by evaluating genotypes of trees from 142 locations in the region. Genotypes controlling growth vigor and growth rhythm were assessed in a common garden. Within southwestern Oregon, two zones are recommended for low elevations (<740 m), two zones for middle elevations (>740 and <1172 m), and four zones for high elevations (>1172 m).

Keywords: Seed zones, geographic variation, genetic variation, adaptation (plant), sugar pine, Pinus lambertiana
