摘　　要：灰斑病是大豆尾孢菌(Cercospora sojina K. Hara)导致的世界性大豆真菌病害,在大豆主要生产区的流行有增长趋势,给生产带来重大损失。大豆尾孢菌变异迅速,已演化出多个具有致病性差异的生理小种,导致现有品种抗性不能满足生产需求。随着分子生物技术的发展,为了获得具有广谱抗性的种质,近年来研究方向从传统的抗病育种转移到对大豆尾孢菌致病机制解析及大豆抗灰斑病基因精细定位上。本文对大豆尾孢菌生理小种的鉴定及其致病性、抗病遗传、抗病育种等方面的国内外研究进展进行了系统综述,并对未来大豆灰斑病的表型精准鉴定、致病机制解析、抗病基因精细定位和抗病育种进行了探讨,为大豆抗灰斑病的进一步研究提供参考。Frogeye leaf spot is a global soybean disease caused by Cercospora sojina K.Hara,and its prevalence in major soybean production areas has resulted in significant yield losses.Cercospora sojina mutates rapidly and evolves multiple physiological races with different pathogenic specificity to overcome the resistance of cultivars.With the rapid development of molecular biotechnology recently,research focuses have been shifted in traditional breeding of resistance varieties to generate germplasm with broad-spectrum resistance,uncover its pathogenic mechanism and delimit resistance genes against soybean frogeye leaf spot.This article provides a systematic review on the identification of physiological races and pathogenicity of Cercospora sojina,inheritance of resistance and resistant breeding.We also explore the precise identification of disease phenotype,analysis of pathogenic mechanism,fine mapping of resistance gene,and resistant breeding,which provides reference for further research on soybean resistance to frogeye leaf spot.
