番茄抗灰霉病育种研究进展

Research progress in breeding of tomato resistance to Botrytis cinerea

灰霉病是设施栽培番茄的主要病害之一,常导致番茄减产30%～40%,给番茄生产造成严重损失,防治该病的根本措施是培育抗病品种。该文对番茄灰霉病菌的侵染、病菌分化、诱导抗性、抗源筛选、抗性基因定位及基因工程等方面的研究进展进行了综述,以期为番茄灰霉病抗性育种提供有益信息,同时结合育种实践对进一步研究进行讨论和展望。

Botrytis blight is one of the major plant disease in protected cultivation,which often causes yield reduction by 30%-40% and results in great economic losses.Planting resistant variety is the main control measure.In order to provide available information on tomato inheritance improvement,the recent research progress in infection and differentiation of pathogen（Botrytis cinerea）,induced resistance,resistance sources screening,resistance gene mapping and genetic engineering were reviewed in this paper.The strategies of further resistance breeding were also discussed.
