Selection of Excellent Families of Pinus yunnanensis
摘要
Abstract
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.关键词
