本研究以长白落叶松种子园子代测定结果品质优良、结实量多、种子发芽率高这３项指标为依据，对种子园优良无性系进行选择，共选出优质、高产、品质优良无性系１０个。以方差分析结果为依据，估算出树高、胸径、材积的遗传力分别为０７２８、０７１３和０６８７；遗传增益分别为７６％、１１７％和８２％；材积生长量超过对照６４４０％，超过各无性系均值１３１１％。这些优良无性系是建立第二代种子园的理想材料，同时也为种子园疏伐、留优去劣提供了科学、可靠的依据。 In this study, Changbai larch seed garden progeny measured results of good quality, strong fruit yield and seed germination rate of these three indicators as the basis of the seed orchard selection of clones, a total of high quality, high yield, excellent quality clones 10 A Based on the results of variance analysis, the heritabilities of tree height, DBH and volume were estimated as 0728, 0713 and 0687, respectively. The genetic gains were 76%, 117% and 82%, respectively. ; Volume of growth exceeds the control 644  0%, more than the mean climacteric 131  1%. These fine clones are the ideal material for establishing the second-generation seed orchard. At the same time, they also provide a scientific and reliable basis for thinning and retention of seed orchard.
