摘要
2012—2014年,对甘肃省内外23个育种及相关单位提供的1 226份小麦品种(系)进行小麦条锈菌分小种及混合菌系接种苗期及成株期抗病性鉴定。结果表明,成株期对当前流行的小麦条锈菌生理小种表现抗病的材料有374份,占总鉴定材料的30.51%;其中全生育期表现抗病的材料有87份,占鉴定材料总数的7.10%。筛选出了一批可供育种及生产使用的小麦抗源材料。
In 2012--2014, the resistance of wheat stripe rust races and mixed bacterial inoculation of 1 226 wheat varieties （lines） from 23 breeding and related units is identified at the seedling stage and the adult stage. The result indicates that the material of disease resistance is 374 samples, which covers 30.51% of total number of identification materials of the current epidemic of wheat stripe rust physiological rust at the adult stage. The material of disease resistance is 87 samples, accounting for 7.10% of total number of identification material at the whole growth period. A number of wheat resistant materials for breeding and production have been selected.
