Combination Selection of Excellent Families and Plus Trees of Phoebe bournei
摘要
Abstract
7-year-old progeny forest of 20 Phoebe bournei families was conducted in Mingxi County,Fujian Province.The height,DBH(diameter at breast height)and volume of individual tree were comprehensive assessed to analyze their genetic gain.The results showed that the height,DHB and stem volume of the 4 excellent families which were selected were increased by 22. 85%,29. 56% and 89. 27%,respectively,and the average genetic gain were 19. 26%,25. 49% and 78. 99%,respectively.1 1 plus trees were further selected from the excellent families, whose average height,average DHB and average stem volume were increased by 53. 16%、84.96%、341. 16%.re-spectively,and their expected genetic gains were 25. 82%、35. 59%、122. 20%,respectively.These excellent indi-viduals could be used as breeding materials of P. bournei.关键词
