对水曲柳无性系种子园4个种源20个无性系的当年生长量、树高和冠幅进行分析.结果表明：4个种源不同性状无性系间变异系数差异较大.水曲柳种源间当年生长量、树高和冠幅差异均达到极显著水平(F分别为37.60,293.53和602.66).无性系间当年生长量、树高和冠幅差异均极显著,通过选择可以获得较高的遗传增益.通过多指标综合评分选出1,4,3,13,14,15和6号为生长性状优良无性系,其中1号无性系为最优无性系.

Current annual increment, tree height, tree crown of 20 clones of four provenances of Fraxinus mandschurica seed orchard were analyzed. The results indicated that the variation coefficient of different traits among clones of four provenances was significant. Current annual increment, tree height and crown were very significant differences (F=37. 6,293. 53 and 602. 66)among provenances. Current annual increment,tree height and crown among clones were significant differences. There will have higher genitic gain by selection. The best clone was No. 1,No. 4,3,13,14,15 and 6 were better clones,which were selected by comprehensive multi-index score on growth character.
