Genetic relationship between reproductive morphology and growth characteristics of Korean pine (Pinus koraiensis)

Abstract

Korean pine (Pinus koraiensis) is an important species for timber as well as pine nut production in Korea. The selection of "plus" trees began in 1959 and seed orchards have been established with grafts and seedlings propagated from these selected individuals. There are 300 “plus” trees and 100 ha seed orchards of P. koraiensis in Korea. Further, 244 open-pollinated families are being tested at four 18.5-ha sites. The main purposes of this study were: (1) to investigate the correlation among cone, seed, and growth traits of P. koraiensis; (2) to examine the possibility that such traits could be useful indicators for progeny testing and further selection; and (3) to provide information on genetic parameters for the establishment of advancedgeneration seed orchards.
