摘　　要：为了搞清我国当前小麦对秆锈病的抗病性状况,于2008-2009年对来自全国小麦主要生产种植区15个省份的182份小麦生产品种和后备品系进行了苗期与成株期抗秆锈病鉴定。结果表明,在供试的品种(系)中,114份对秆锈病表现抗性,占供试材料的62.64%,其中来自东北春麦区、北方冬麦区和黄淮海冬麦区的品种(系)对秆锈病抗性较强;部分地区材料对秆锈病的抗性较差,其中江苏省的13份品种(系)全部感病。这说明虽然我国当前小麦生产品种和后备品系对秆锈病的抗性普遍较强,但仍然存在相当数量的感病品种,秆锈病发生与流行的威胁依然存在。182 wheat cultivars(lines) from fifteen provinces of China had been identified for resistance to stem rust at seedling and adult stage during 2008 to 2009.The results indicated that 114 wheat cultivars(lines) were resistant,accounted for 62.64% of all tested materials.Among them,cultivars(lines) from the Northeast spring-wheat region,the Northern winter-wheat and Huang Huai Hai winter-wheat region showed good resistance,cultivars(lines) from some provinces lack resistance,and even all thirteen cultivars(lin...
