Abstract Non-host resistance is the most common form of disease resistance exhibited by plant
against the majority of pathogens of other species. The durable and broad-spectrum defense of non-
host resistance suggests that non-host resistance in plant should be the important resource for crop
disease-resistant breeding and the research hotspot of disease resistance. This review focused on
genetic research and resistant mechanism of plant non-host resistance. The difficulty and future
prospect of non-host resistance study were analyzed
