摘  要:2015~2019年采用苗期人工接种,田间病圃异地自然诱发鉴定方法,对1 545份吉林省水稻区试品种(系)进行了稻瘟病抗性鉴定和评价。结果表明,5年苗瘟、叶瘟、穗瘟的平均抗病率分别为55.47%、76.57%和43.24%,说明吉林省区试水稻品种抗性较好。从不同时期的发病情况看,叶瘟的抗性水平高于苗瘟和穗瘟,即从分孽期到抽穗期,对稻瘟病的预防和防治存在较大空间。From 2015 to 2019, 1 545 varieties(lines) of the regional test in Jilin province were identified and evalu-ated by artificial inoculation at seedling stage and natural induction identification in the field disease nursery. Theresults showed that the average disease resistance rates of seedling blast, leaf blast and panicle blast were 55.47%,76.57% and 43.24%, respectively, indicating that the resistance of rice varieties in regional trials in Jilin Provincewas better. And the resistance of leaf blast was higher than the seedling blast and spike blast in different period stag-es, that is, there was a large space for the prevention and control of rice blast from tillering stage to heading stage.
