摘　　要：为了发掘引种峦大杉种质资源,应用5株优势木对比法在福建省三明市、泉州市和龙岩市引种的峦大杉优势人工林中开展无性繁殖原株和优树选择。筛选出的12株无性系繁殖原株树高、胸径和单株立木材积均值较优势木均值大10.10%、13.57%和38.35%,这些无性繁殖原株是开展无性繁殖体系构建,优良无性系筛选的繁殖材料。筛选出的5株优树树高、胸径和单株立木材积均值分别较优势木均值大11.95%、20.07%和54.73%,较选优林分均值大27.48%、38.69%和108.53%,年均生长量分别为1.30m、2.39cm和0.0145m^3,这些优树是开展有性育种的种质材料。For exploring germplasm resources of Cunninghamia konishii Hayata, ortets and elite trees were selected by the method of 5 dominant trees comparison in 3 C. konishii dominant stands those were established in Sanming, Quanzhou, and Longyan, Fujian Province. There were 12 individuals were selected as ortets, getting 10.10%, 13.57% and 38.35% growth dominant in tree height, diameter at breast height(DBH), and volume comparing to dominant trees. Furthermore, there were5 candidate trees were considered as t elite trees, getting 11.95%, 20.07% and 54.73% growth dominant in tree height,DBH, and volume comparing to dominant trees. The annual growth of tree height, DBH and volume of these elite trees was1.30 m, 2.39 cm, and 0.0145 m^3 respectively, being more severally 27.48%, 38.69%, and 108.53% than those of the choice stands. Finally, the selected ortets and elite trees were important breeding materials for C. konishii.
