摘　　要：13个兴凯湖松家系间的苗高性状存在丰富的变异,变异范围在25.85%～35.27%之间;地径性状变异较小,平均变异系数为26.64%.方差分析与多重比较结果表明,家系间的苗高与地径生长差异均达到显著水平,地径性状表现最好和最差的家系分别为JDG08和JXI21,生长最快的家系较生长最慢的家系提高26.82%;苗高性状表现最好与最差的家系分别为JDG16和JXI21,生长最快的家系较最慢的家系提高35.50%.综合2个性状,表现较好的家系为JDG19、JDG12、JXI13及JDG16.There were rich height variations among the thirteen families of Pinus ussuriensis Cheng et Y.W.Law and the variations range was from 25.85% to 35.27%.The diameter variations were smaller and the average coefficient was 26.64%.We analyzed the variance and multiple comparisons.The results showed that the differences of height and diameter growth were significant among the families.The best family of diameter trait was JDG08 and the worst was JXI21.The fastest family increased by 26.82% compared the slowest.The best family of height was JDG16 and the worst was JXI21 and the fastest increased by 35.05% compared the slowest.Integrated the two traits,the better families were JDG19、JDG12、JXI13 and JDG16.
