This review takes an evolutionary view of breeding crops for durable resistance to disease. An understanding of coevolution between hosts and parasites leads to predictors of potentially durable resistance, such as corresponding virulence having a high fitness cost to the pathogen or resistance being common in natural populations. High partial resistance can also promote durability. Whether or not resistance is actually durable, however, depends on ecological and epidemiological processes that stabilize genetic polymorphism, many of which are absent from intensive agriculture. There continues to be no biological, genetic, or economic model for durable resistance. The analogy between plant breeding and natural selection indicates that the basic requirements are genetic variation in potentially durable resistance, effective and consistent selection for resistance, and an efficient breeding process in which trials of disease resistance are integrated with other traits. Knowledge about genetics and mechanisms can support breeding for durable resistance once these fundamentals are in place.

作物对疾病的持久抵抗力:达尔文的观点。

这篇综述从进化论的角度来看待培育作物以获得持久的抗病性。对宿主和寄生虫之间共同进化的理解导致了潜在持久抗性的预测因子,例如对病原体具有高适应性成本的相应毒力或自然种群中常见的抗性。高局部电阻也可以促进耐久性。然而,抗药性是否真正持久取决于稳定遗传多态性的生态和流行病学过程,其中许多在集约化农业中是不存在的。仍然没有持久抗性的生物学、遗传或经济模型。植物育种和自然选择之间的类比表明,基本要求是潜在持久抗性的遗传变异,有效和一致的抗性选择,以及将抗病性试验与其他性状相结合的有效育种过程。一旦这些基本原理到位,有关遗传学和机制的知识可以支持持久抗性的育种。
