摘　　要：鸭茅是一种著名的温带牧草,容易感染锈病。本研究从植株感病率、感病严重度、病情指数和反应指数4方面对国内37份鸭茅种质资源(野生资源35份)进行锈病的病情调查及抗病性研究。研究初步揭示了鸭茅锈病的发病规律,研究结果显示02-106、02-107、90-130、02-115等4份材料对鸭茅锈病具有较好抗性,可作为育种材料进一步深入研究。Orchardgrass is a kind of famous forage in temperate zone with higher infection of rust disease.According to the infection analysis of rust in field,37 orchardgrass accessions（35 of them were natural accessions） were tested in the paper.The infection phenomenon of rust was investigated and the result suggested that accessions of 02-106,02-107,90-130,02-115 could moderately resist to both leaf and stem rust.All of the four accessions are of more value for rust resistance reproductive selection.
