| 摘 要： | 按照"三株大树法"在辽宁省森林经营研究所草河口实验基地5处不同林龄红松人工林中选择10株结实丰产型优树,调查优树单株结实量、胸径和树高等生长指标,通过对3a结实量的遗传增益计算,结果表明,所选的10株优树结实量的平均遗传增益为26.32%。生产中可选择优树穗材作为繁殖材料营建红松结实高产无性系果林。

| Abstract: | Ten strains of high-yielding plus tree were selected according to the comparison method among dominant tree in five plots with different ages in Caohekou Experimental Base of Liaoning Province Forest Management Research Institute.Result shows that the average genetic gain of the 10 strains is 26.32%;selecting plus tree which was used as breeding material to construct high-yielding clonal Pinus tabulaeformis fruit-forest can obtain considerable economic benefits. |
