Book Description
Excerpt from Genetic Gains From Tree Improvement of Ponderosa Pine in Southern Idaho The basis for a practical tree improvement program of ponderosa pine in southern Idaho is contained in l6 - year old family evaluation tests. As detailed in preceding publications (wang 1967; Wang and Patee 1974, 1976; Rehfeldt primary objectives of the tests are: to develop seed zones and seed transfer guidelines that account for genetic adaptations to natural environments, to identify outstanding individual trees and populations from which wind-pollinated seeds will provide genetic gains to artificial reforestation, and to provide materials and information prerequisite to future breeding programs. The present analyses of 16-year height utilize experimental materials more fully described in a series of papers that have assessed performance at ages 3, 8, and 11. Test plantations currently require thinning; therefore, it is appropriate to consider alternative plans for the future research program and for development of seed orchards.
