花生白绢病病原菌致病力分化的研究进展

花生白绢病是由齐整小核菌（Sclerotium rolfsii Sacc.）侵染引起的一种重要的土传真菌性病害，在世界各花生产区都有发生，近10年来在我国花生主要种植省份流行危害，造成较大经济损失，成为制约花生产业发展的重要因素。本文对花生白绢病病原菌的特点、致病力分化、致病因子及引起致病力分化的原因等方面进行综述，期望为这一病害的防控提供参考。

Progress on pathogenicity differentiation in Sclerotium rolfsii isolates from peanut

Peanut southern blight is an important soil-borne fungal disease caused by Sclerotium rolfsii Sacc, widely distributed in most peanut producing countries. During the past decade, it has become an important disease which restricted peanut production in China, and causing significantly economic losses. In this review, characteristics, pathogenicity differentiation, and factors affecting disease development of peanut southern blight were discussed in order to provide reference for prevention and control of the disease.
