【摘要】 通过田间自然诱发和牙签嵌入法人工接种相结合的鉴定方法，对收集的86份吉林省主栽水稻品种进行了纹枯病鉴定，以明确其对该病的抗性表现。自然诱发鉴定筛选出30份中抗以上的水稻品种，人工接种鉴定筛选出25份中抗以上的水稻品种，两种鉴定结果同时筛选出17份中抗的水稻品种。对这两种鉴定结果进行比较，符合率为88.4%。该研究为抗纹枯病水稻品种的选育提供参考依据。更多还原

【Abstract】 By combining the identification methods of natural induction and toothpick inoculation in fields, we tested86 commonly cultivated rice varieties of Jilin Province for their resistance to sheath blight. The identification method of natural induction identified 30 rice varieties with moderate or higher resistance, the identification method of artificial inoculation identified 25 rice varieties with moderate or higher resistance. Both methods identified 17 rice varieties conferring moderate or higher resistance to sheath blight. The coincidence rate of the two identification methods was 88.4%. This study can provide valuable information for breeding with sheath blight resistance of varieties.更多还原
