摘　　要：对51份春小麦品系材料进行了抗锈性苗期混合菌、成株期分小种及混合菌鉴定。结果表明,对目前流行的条锈菌优势生理小种成株期表现抗病的有34份,占鉴定材料的66.67%,其中表现免疫近免疫39.22%。分小种鉴定的结果为:对条中32号免疫的材料有40份,占78.43%;对条中33号免疫的材料有38份,占74.5%。51 spring wheat strain of our breeding room were identified stripe rust resistance for mixture isolates at the seeding stage,physiological races and mixture isolates at adult stage.The results showed that 34 strain performanced resistance to the current epidemic stripe rust at the adult stage,accounting for 66.67% of the total identification materials,in which the immune completely and immune nearly performance of the 39.22%.40 strain performanced immune completely to CY32,accounting for 78.43%.38 strain performanced immune completely to CY33,accounting for 74.5%.
