【摘要】 保护生物多样性在林木育种中必须予以重视。传统的林木育种主要考虑遗传增益。长期育种则以维持育种群体的变异性为主要目的。具有丰富生物多样性的天然森林群体是长期育种的基础。长期育种研究应以物种生物学、群体遗传学和居群生态学等为理论基础。主要研究森林群体的性质及群体的动态变化规律。传统林木育种的研究方向、研究内容及林木育种学的教学内容等都应予以适当的调整和补充。更多还原

【Abstract】 Protecting biodiversity must be emphasized in tree breeding. The breeders used to pay more attention togenetic gain in traditional tree breeding. Otherwise long term breeding aims at maintaining genetic variationof forest Population. Abundent biodiversity in natural forest land is the basic for long term breeding. Theproperty and developing tendency of forest POpulation will be studied mainly. So, the direction and object fortraditional tree breeding research as well as the teaching courses for genetics and breeding of tree must beadjusted and supplemented.更多还原
