前言赤霉病是小麦生产上重要病害之一。随着抗源筛选和抗赤霉病小麦育种工作的开展,国内外对鉴定小麦品种抗赤霉病的方法,也进行了许多研究。我国五十年代首先研究出用带菌麦粒土表接种,随后许多单位又采用了在小麦抽穗开花期,用赤霉菌分生孢子或子囊孢子悬浮液直接喷雾,用病穗率病情指数鉴定品种抗性,一直沿用至今。七十年代以后又进一步研究出在抽穗期,单花注射子囊孢子,以及采集麦穗到室内,离体剪颖滴注菌液,用发病小穗数统计分析,鉴定品种抗性等方法。在国外,匈 Introduction Fusarium head blight is one of the most important diseases in wheat production. With the screening of anti-source and the development of wheat breeding against scab, many researches have been done on the identification of wheat scab resistance at home and abroad. In the fifties of our country, we first studied the inoculation of wheat with soil-inoculated wheatgrass, followed by many units in the wheat heading and flowering period, spraying directly with the spores or the ascospores of Gibberella sp. Sex, has been in use today. Seventies after further study in the heading, a single flower injection ascospore, as well as the collection of wheat ears to the room, in vitro scissors instillation bacilli, statistical analysis of the number of spikelets, identification of varieties of resistance and other methods.
