摘要
对于育种工作者来讲,只有了解和掌握林木群体的遗传变异模式和规律,才能充分发掘其遗传潜力,制定合理的育种策略,从而获得较大的遗传增益。马尾松(Pinus massonianaLamb.)乃是我国南方各省主要的工业用材树种,遗传变异极为丰富,具有很大的选择潜力。众多的性状(包括生长、形态、物候、开花结实性和适应性等)
Studying the genetic variation of natural population of masson pine, we found that there were significant differences between provenances for tree height, base diameter and survival rate. It was possible to acquire moderate genetic gains by provenance selection. Stand selection could be of no effect because of no differences between stands within the same areas,
