Growth and wood quality characters such as height, DBH, specific gravity, traceried length and width were measured for 16-year-old open-pollinated progenies of 38 selected plus trees of Abies holopleylla Max. The results were as follows : 1) The superior families in growth and wood quality characters were Chonbuk 4(498.2㎝) and Kyonggi 9(485.7㎝) for height, Kyonggi 12(9.2㎝) and 9 (9.1㎝) for DBH, Kaongbuk 2 (0.480) and Kangwon 7(0.473) for specific gravity, Kyonggi 9(2.77mm) and Kangwon 11 (2.71mm) for tracheid length and Kyonggi 9(0.039mm), Kangwon 11, 12 and Kyunggi 7(0.036mm) for tracheid width, respectively. 2) There were significant differences among the families in height and specific gravity at 1% and 5% level. 3) There were high significant negative correlations between specific gravity and other characters such as height, DBH, tracheid length and width at 1% level(r=-0.242^(**)-0.635^(**)). 4) The heritabilities were 0.55 for height, 0.25 for DBH, 0.44 for specific gravity, and 0.24 for tracheid width.
