Department of Forest Genetics Resources, Korea Forest Research Institute, Suwon 441-350, Korea(Received November 15, 2012; Revised November 23, 2012; Accepted December 4, 2012)ABSTRACTThis research was performed to analyze grow th performance and pattern of eighteen families ofhinoki cypress ( Chamaecyparis obtusa ), which were imported in Jeju region. The growths of ako-7,YMuei-1, and Sangsong-9 families were superior to other families whereas those of Sanguen-3,Yago-6, and Hyena-2 families were poor. The height growth between age 9-year to 15-year wassuperior to those between other ages. No specific growth pattern was observed in the diameter atbreast height (DBH) by ages. Family heritability of height, DBH, and volume were estimated at 0.68,0.75, and 0.75, respectively. Pearsons correlation analysis showed that there was little juvenile-maturecorrelation in the growth of C. obtusa.Key words : Growth performance, Patterns, Family heritability, Age correlation, Chamaecyparis obtusa |
