摘　　要：对受松突圆蚧危害的28个马尾松家系相关的6个指标进行主成分分析和聚类分析,探讨了28个马尾松家系抗松突圆蚧危害的特点。结果表明,家系330、386、318、246、465、662、CK1、232等8个家系不易受松突圆蚧侵害;家系439、458、469等3个家系易受松突圆蚧侵害。In this paper, the 6 injury-respond indexes of 28 masson pine strains due to Hemiberlesia pitysophila Takagi were analyzed by use of the principle component analysis method and the cluster analysis method. The resuits indicated that the strains, namely 330, 386, 246, 465, 662, CK1 and 232, were not sensitive to H. pitysophila, by contrast, that the strains 439, 458 and 469 could be easily injured by this pest.
