摘　　要：以35个黄山松家系为研究对象,测定其球果性状和种子特性相关指标,采用相关分析、逐步回归分析和聚类分析等方法分析了各指标的变异性和相互关系。结果表明,各指标的变异系数范围在4.73%~21.67%之间;不同家系黄山松的各指标间均存在极显著差异;球果纵径、横径、单果鲜重、大小对种子的千粒重有极显著的影响,其中球果的横径是最主要的决定因子;通过聚类分析把35个家系的球果分成三个类型,第一个类型所包含的1号、14号、15号和33号家系可以作为黄山采种用优良候选家系。Taking 35 families of Pinus taiwanensis as the research objects,measured their cone traits and seed characteristic indicators,and analyzed the variability and interrelationships of these indicators using methods such as correlation analysis,stepwise regression analysis,and cluster analysis.The results showed that the variation coefficient range of the indicators was between 4.73%and 21.67%.There were extremely significant differences among the indicators of different Pinus taiwanensis families.The longitudinal diameter,transverse diameter,single fruit fresh weight,and size of the cones had extremely significant effects on the thousand-seed weight of the seeds,with the transverse diameter of the cones being the most important determinant factor.The cones of the 35 families were divided into three types by cluster analysis,and the first type,which included families 1,14,15 and 33,could be considered as excellent candidate families for seed collection in Huangshan.
