Establishment of the Second-Generation Selected Population of Slash Pine in the Cooperative Forest Genetics Research Program

A total of 886 individuals have been selected to comprise the second generation of improved slash pine in the Cooperative Forest Genetics Research Program (CFGRP). The bulk of the second-generation selections were made from a base population which included a total of 2373 original first-generation selections and the best offspring from each of 2700 full-sib crosses among first-generation parents. Best linear prediction was used to predict breeding values for volume and fusiform rust resistance, and the 5073 candidates were ranked according to their predicted breeding values. The primary objectives in the second-generation selection were: 1) to maximize genetic gain for the economically important traits of volume growth and rust resistance, and 2) to maintain a broad genetic base.
