Host-plant resistance is an efficient, economical and environmentally benign approach used to manage many pests and diseases of agricultural crops. After nearly a century of research, the resources and tools have become more refined, but the basic tasks in breeding for resistance have not changed. Resistance must be identified, incorporated into elite germplasm, and deployed in a form useful to growers. In some instances, biotechnology has expedited this process through incorporating a foreign gene(s) for resistance into elite germplasm. The USDA Agricultural Research Service (ARS) has made significant contributions in the development of germplasm with resistance to insects, nematodes and plant diseases. Because resistant plant varieties are an essential component of sustainable production systems, ARS is committed to developing techniques and germplasm to help meet this goal.
寄主植物抗性是一种用于防治多种农作物病虫害的高效、经济且环境友好的方法。经过近一个世纪的研究，资源和工具变得更加精细，但抗性育种的基本任务并未改变。必须鉴定抗性，将其整合到优良种质中，并以对种植者有用的形式进行推广。在某些情况下，生物技术通过将外源抗性基因整合到优良种质中加快了这一进程。美国农业部农业研究局（ARS）在开发抗昆虫、线虫和植物病害的种质方面做出了重大贡献。由于抗性植物品种是可持续生产系统的重要组成部分，ARS致力于开发技术和种质以帮助实现这一目标。
