Plus Trees Progeny Testing and Superior Family Selection of Fokienia hodginsii
摘要
Abstract
Using BIB design,129 Fokienia hodginsii plus trees which were from Fujian and Hunan were collected ,the progeny test was carried out on the State-owned Forest Farm of Yong′an.The result showed that there were significant differences among tree height,DBH and volume at the age of 5,8 and 11.The growth traits phenotypic variation coefficient was larger ,with the volume of the phenotypic variation coefficient of maximum; the average tree height , DBH, average individual volume in the same area between groups,family,and the difference between group and family interaction had reached extremely significant level .Based on genetic vari-ation analysis,nine superior families such as J007,J012 etc.were selected from 81 families.Average tree height,DBH and volume of the nine superior families of the 11-year-old one were 7.92 m,13.86 cm and 0.057844 m3 ,those were larger 5.74%、13.42%and 27.45%than population means , respectively.Average genetic gain of tree height , DBH and volume were 4.57%、10.14% and 20.50%,respectively.Other four superior families such as J 010、B003 etc.were selected from forty-eight families.Average tree height,DBH and volume of the other four superior families in the 11-year-old were 7.63 m、13.03 cm and 0.050312 m3 ,those were 3.81%,9.77%and 18.87%larger than population mean value ,respectively.Average genetic gain of tree height ,DBH and volume were 2.19%、5.07%and 7.41%,respectively.All of these superior families could be used as propagating materials in production.关键词
