摘要： 为了探讨黑龙江省南部稻区水稻品种对稻曲病的抗性级别及稻曲病田间发病情况，采用自然感病辅以人工接种的方法，调查分析了62份常规粳稻田间稻曲病发生病穴率、病穗率、稻曲球粒数等指标。结果表明：病穴率范围为0.89%~90.00%，平均病穴率22.49%，病穗率范围为0.04%~14.11%，平均病穗率2.63%，病情指数范围0~5.02，平均病情指数1.08，筛选得到‘松粳14’、‘W01’、‘W38’等3个免疫品种，42个抗性品种，抗性品种共占87.10%，总体抗感比为54:8。黑龙江省南部稻区大多数水稻品种对稻曲病具有抗性，品种间对稻曲病存在抗性差异，生产上应该提倡种植抗性强的品种以防止病害发生。

Abstract: To discuss the resistance level and the occurrence of rice false smut in rice planting area of southern Heilongjiang, the natural infection and artificial inoculation were used to analyze the hole disease rate, spike disease rate and false smut balls of 62 conventional japonica rice varieties. The results indicated that: the hole disease rate range was 0.89%-90.00%, the average hole disease rate was 22.49%; the spike disease rate range was 0.04%-14.11%, the average spike disease rate was 2.63%; the disease index range was 0-5.02, the average disease index was 1.08.‘Songjing14’,‘W01’and‘W38’were selected as immune varieties and 42 varieties were identified as resistant varieties, which accounted for 87.10% of the total, and the total ratio of resistant to susceptible varieties was 54:8. Most rice varieties in southern Heilongjiang were resistant to rice false smut, and the resistance difference existed among rice varieties.
