在整个群体遗传学史上，“适应度”一词的应用方式不同，定义也不同。本文提出了区别（表型）适合度、（基因型）适合度、适应性、适应性和持久性五个概念和定义。虽然适合度组成部分的遗传力较低，但可以实现实质性的遗传变化，育种计划应包括育种目标中的基因型适合度（对于已知的QTL）和适合度性状，如生育力和寿命，以及生产性状。
The term ‘fitness’ has been applied differently and with different definitions throughout the history of population genetics. Five concepts and definitions are presented~– distinguishing (phenotypic) fitness, (genotypic) fitness, adaptedness, adaptability and durability. While the heritabilities of fitness components are low, substantial genetic change is achievable, and breeding programs should include in the breeding objectives genotypic fitness (for known QTLs) and fitness traits such as fertility and longevity, as well as production traits.
