ABSTRACT
A breeding population of Quercus glauca has been established via simple direct selection. Seedlings from naturally crossed seeds of 35 selected families growing in Jeju Island were placed using stroll repeated planting into two experimental forest located at Hannam and Sanghyo in Jeju. After 3 years of planting, characteristics of growth were examined. Growth pattern of trees in Sanghyo was better than those in Hannam. The average heights of filial were 66.8 cm in Hannam and 92.5 cm in Sanghyo. Root collar diameters of filial in Hannam and Sanghyo were 9.3 mm and 12.2 mm, respectively. A great weather differences especially in precipitation and temperature were shown between two test sites. The result of difference of growth pattern between two sites could be useful in provenance adaptability test. Data within families and individuals obtained from this study was also useful for establishment of seed orchard of Q. glauca.

적요

국내에 자생하고 있는 상록성 참나무류 중 종가시나무(Quercus glauca)의 기본육종집단을 조성하였다. 2002년부터 2005년에 걸쳐 제주도지역의 자생집단내에서 모수의 우수한 표현형(phenotype)에 의한 직접선발(direct selection) 과정을 거쳐 종가시나무 35가계를 선정하였다. 이들의 자연교잡된 종자로부터 양성된 차대목을 2006년 6월 국립산림과학원 난대산림연구소 시험림내 2개 장소(한남시험림, 상효시험림)에 열식 반복으로 식재하였다. 식재 후 3년이 경과한 2009년 9월에 차대목의 생장검정을 실시한 결과, 한남시험림의 차대목 수고평균은 66.8cm로 나타났으며 상효시험림에서는 92.5cm로 조사되었다. 근원경에서는 한남의 차대목들이 9.3mm, 상효의 차대목들이 12.2mm로 조사되어 상효지역에 식재된 차대목들의 생장이 더 양호한 것으로 나타났다. 식재된 두 지역의 기상인자 중에서 평균온도와 강수량에 있어 큰 차이를 보이고 있으며 이에 따라 두 지역간의 차대목 생장에 영향을 미치는 한 가지 요인으로 분석되었다. 또한 가계간과 가계내개체간에도 차대목의 수고생장 정도에도 큰 편차를 보였는데 이와 같은 결과는 향후 지역적응성 및 선발차(selection differential)와 유전력(heritability) 검증을 거쳐 조성될 난대수종 채종원 조성의 기본 단계 재료로 활용될 수 있을 것이다.
