【摘要】 杉木无性系选育必须充分利用有性改良成果和种内多种层次的遗传效应,必须重视种源以及家系内无性系间的变异.多层次选育效果最佳,方法简单,见效迅速,增益明显.
【Abstract】 It must be fully utilized for Chinese fir(Cunninghamia lanceolata) clonal selection that the sexual improvemente results and the interspecific genetic effects of multiple stages.The greater selection response and significant gain could be easily and rapidly obtained by the multiple stage breeding.
