In serious situations, soybean white mold (SWM) disease caused by Sclerotinia sclerotiorum (Lib.) de Bary can result in yield losses of up to 60%. Current management of the disease involves an integrated approach with a high dependence on fungicides; however, fungicide usage increases production costs and environmental pollution. Alternatively, using resistant cultivars may be another effective way to control the SWM epidemic and reduce soybean crop yield losses. Many studies on identification and genetic dissection of the soybean’s resistance to SWM disease have been reported. This study summarizes the recent research advances in the resistance evaluation and genetic base of resistance to SWM. Different screening protocols and parameters for the evaluation of SWM disease were used in both controlled conditions and fields, and quite a few soybean lines were identified as having SWM resistance. The literature on soybean resistance mechanisms for dealing with the fungus was examined, and the quantitative trait loci (QTL) for SWM detected by both linkage and association mapping methods were summarised for further use. Obvious progress on conventional and molecular breeding for resistance to SWM has also been made. The present review provides comprehensive and up-to-date knowledge about the current status of the genetic control of white mold and serves as a base to direct future works on breeding cultivars for stable resistance to Sclerotinia sclerotiorum.

大豆白霉病抗性种质资源评价及遗传改良研究进展

在严重的情况下,由核盘菌引起的大豆白霉病 (SWM)(Lib.) de Bary 可导致产量损失高达 60%。目前对该病的管理涉及高度依赖杀菌剂的综合方法;然而,杀菌剂的使用增加了生产成本和环境污染。或者,使用抗性品种可能是控制 SWM 流行和减少大豆作物产量损失的另一种有效方法。已经报道了许多关于大豆对 SWM 病害抗性的鉴定和遗传剖析的研究。本研究总结了近年来SWM抗性评价及遗传基础研究进展。在控制条件和田间使用不同的筛选方案和参数来评估 SWM 病害,并且确定了相当多的大豆品系具有 SWM 抗性。研究了有关大豆抗性机制的文献,并总结了通过连锁和关联作图方法检测到的 SWM 数量性状位点 (QTL) 以供进一步使用。SWM抗性的常规和分子育种也取得了明显进展。本综述提供了关于白霉菌遗传控制现状的全面和最新知识,并作为指导未来培育稳定抗性的栽培品种工作的基础。菌核病菌
