研究福建红锥不同种群与家系变异表明,不同种群和家系存在极显著的生长差异,来自福建金山林场的红锥种群具有明显的生长优势。按照育种值评选出11个优良家系,其地径、树高、胸径和冠幅的遗传增益分别为13.5%,9.5%,21.1%,12.3%,家系选择效果明显优于种群选择。
Studying on the variation of different populations and pedigrees in Fujian red cone showed that there were extremely significant differences in growth among different populations and families. The population of red cone from Jinshan Forest Farm in Fujian Province had obvious growth advantages. Eleven elite families were selected according to the breeding value. The genetic gain of diameter, height, DBH and crown were 13.5%, 9.5%, 21.1% and 12.3%, respectively.
