摘要
对日本落叶松初级种子园６０个自由授粉家系研究结果表明，家系的树高、胸径、材积等生长性状都存在着明显遗传变异。选出的１７个优良家系的平均遗传增益，树高为４３％，胸径为１３１％，材积为２６１％。优良家系可在豫西伏牛山区造林中应用推广。
Experiment of clone and site interaction variance analysis and differental examination has been done. Passing by evaluation the clonal ecological stability and synthesive apparent, 83002 and 84023 are fast growing,stable clone.Genetic gain of six year trunk volume is seperately more 23 7%～46 0%,20 7%～32 4% than A05,8048. Altogether some adaptable plus clone has been chosen to spread in different aera.
