Maize is the world's most produced crop, providing food, feed, and biofuel. Maize production is constantly threatened by the presence of devastating pathogens worldwide. Characterization of the genetic components underlying disease resistance is a major research area in maize which is highly relevant for resistance breeding programs. Quantitative disease resistance (QDR) is the type of resistance most widely used by maize breeders. The past decade has witnessed significant progress in fine-mapping and cloning of genes controlling QDR. The molecular mechanisms underlying QDR remain poorly understood and exploited. In this review we discuss recent advances in maize QDR research and strategy for resistance breeding.
玉米是世界上产量最高的作物，为人类提供了食物、饲料和生物燃料。玉米生产在全球范围内不断受到破坏性病原体的威胁。对疾病抗性遗传组成的特征分析是玉米研究的一个主要领域，这对于抗性育种计划具有重要意义。数量抗性（QDR）是玉米育种者最广泛使用的抗性类型。过去十年，在控制 QDR 的基因的精细定位和克隆方面取得了重大进展。QDR 的分子机制仍知之甚少，也未得到充分利用。在这篇综述中，我们讨论了玉米 QDR 研究的最新进展和抗性育种策略。
