树木育种学中遗传力、重复力和遗传增益的概念及思考

摘要

Heritability, repeatability and genetic gain in percent are important terms and fundamental concepts in tree breeding, but there are various descriptions of their definitions in different articles. This paper analyzed the multifarious definitions and biological concepts of the three terms based on literature. In addition, the opinion on usage of them was given.%遗传力、重复力和遗传增益是树木遗传育种学中重要的术语，常用来评价育种工作取得成效的多少，但在不同文献中的理解有些不一致。本文对遗传力、重复力和遗传增益的生物学概念和定义式进行分析和讨论，并对术语的使用提出建议。
