摘　　要：研究云南松优良家系选择,结果表明:云南松不同家系间在生长性状和木材品质性状上差异显著,综合选择出优秀家系16个和良好家系29个,优秀家系树高、胸径、单株材积、通直度和木纹理扭转度的遗传增益分别为12.63%、26.74%、65.83%、9.44%和57.88%,良好家系树高、胸径、单株材积、通直度和木纹理扭转度的遗传增益分别为14.32%、20.47%、51.85%、10.10%和31.63%,优良家系具有木材生长量大、干形通直、木纹理扭转小的特点,可极大地提高新建云南松生态林和国家储备林的质量和效益。The selection of excellent families of Pinus yunnanensis was studied,the result showed that there were significant differences in growth and wood quality traits among different families of Pinus yunnanensis.16 excellent families and 29 good families were comprehensively selected.The genetic gains of tree height,breast diameter,individual volume,straightness,and wood grain twist in excellent families were 12.63%,26.74%,65.83%,9.44%,and 57.88%,respectively.The genetic gains of tree height,diameter at breast height,individual volume,straightness,and wood grain torsion of good families were 14.32%,20.47%,51.85%,10.10%and 31.63%,respectively.Excellent families with characteristics of large wood growth,straight stem shape,small twisting of wood grain can greatly improve the quality and efficiency of new-ly built Pinus yunnanensis ecological forests and national reserve forests.
