在植物病原物与寄主植物相互关系的研究中提出了植物病原物寄生适合度(parasiticfitness)的概念,这是迄今人们从长期与植物病害作斗争中得出的较为全面的认识之一。运用病原物寄生适合度的概念,对探讨植物病害的流行机制和指导抗病品种的选育、推广布局等都具有重大的意义。本文还讨论了研究植物病原物寄生适合度的方法。

The concept of parasitic fitness of plant pathogens has been proposed in the study of the relationship between plant pathogens and host plants, which is one of the more comprehensive understandings so far obtained from the long-term struggle against plant diseases. The use of the concept of parasitic fitness of pathogens is of great significance in exploring the epidemic mechanism of plant diseases and in guiding breeding, popularization and distribution of resistant varieties. This article also discusses ways to study parasitic fitness of plant pathogens.
