小麦赤霉病的抗性鉴定方法,一直是人们关注的问题。许多学者对穗部赤霉病的接种方法、鉴定标准等方面作了研究;对穗部以外的部位如叶片、叶舌、叶鞘等的接种鉴定虽有研究,但尚未得出明确结论。为此,我们对离体叶片接种时期、接种方法和鉴定指标进行了研究,旨在提高育种效率,为早期鉴定、筛选材料提供方法和标准。本试验以苏麦3号等12个小麦品种为供试材料,菌株则系从鄂麦9号上分离的GibberellaZeae武昌菌株。

Resistance of wheat scab has been identified as a problem of concern. Many scholars have made studies on the methods of inoculation and identification of scab and other identification criteria. The studies on inoculation of parts other than the panicle, such as leaves, ligules and leaf sheaths, have not been conclusive yet. To this end, we in vitro leaf inoculation methods, inoculation methods and identification of indicators were studied to improve breeding efficiency, early identification and screening materials to provide methods and standards. Twelve wheat cultivars, such as Sumai 3, were used as tested materials in this experiment. The strain was derived from the strain of Gibberella Zeae Wuchang isolated from Emai 9.
