摘要：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。
The study of variation on seeding growth of Castanopsis hystrix in different population and families in FuJian province was reported in this paper.The results showed that the growth of different population and families were significant different.FuJian forestry farm Castanopsis hystrix population had obvious growth advantage.There are 11 excellent population and families were choosed.Their genetic gains of ground diameter,high growth,diameter breast high and canopy cover were 13.5%,9.5%,21.1% and 12.3%,effect of families selection was better than population selection.
