闽楠优树子代生长性状与形质性状综合选择
|
摘要
测定、分析福建省永安国有林场闽楠8个种源41个家系的生长性状与形质性状及其遗传变异规律.结果表明:闽楠家系在树高、胸径、单株材积生长性状上差异均达到极显著水平,通直度形质性状差异达到显著水平;冠幅、分枝度差异未达到显著水平.以11 a林龄单株材积和树高、胸径、通直度作为选择依据,综合选出7个优良家系,平均树高、胸径、单株材积分别为8.68 m,11.48 cm,0.047 743 m3,家系遗传力分别为0.872 5,0.791 7,0.855 7,平均遗传增益分别为12.96%,16.84%,48.51%.这些优良家系可用于闽楠造林绿化和无性繁殖.
The growth character,form quality character and genetic variation of Phoebe bournei plus trees with 41 families of 8 provenance on Yong'an National Forest Farm in Fujian were determined and analyzed. The result showed that there were very significant differences in developing character for tree height,DBH,single volume among the families,there were significant differences in form-quality traits for straightness.There were not significant difference in crown width and branch degree.Taking 11-year-old single volume and tree height,DBH and stem form index for selection,average height,average DBH and average single volume of 7 superior families were 8.68 m,11.48 cm,0.047 743 m3 respectively,the genetic power were 0.872 5,0.791 7,0.855 7 respectively; average genetic gain were 12.96%,16.84%,48.51% respectively.These superior families may be useful for planting and clone materials for propagation of P bourne.
