| 摘 要： | 应用我省稻区的82个稻瘟病菌株接种,分析了吉林省历年种植的水稻品种的抗瘟性。结果表明:近几年新育成的品种抗瘟性已有较大的提高,九稻41、通丰8号和九稻33的抗性优异,抗谱在95%以上,九稻44、吉玉粳、丰选2号、九稻46、九稻42、九稻39、超产1号、超级稻1号和通粘8号等品种的抗谱也较高。同一品种对不同地区菌株的抗谱有较大差异,生产上可根据其在不同地区的抗性表现合理搭配种植。

Studies on resistance to rice blast in some rice varieties commercially grown in Jilin province |
| |
| Abstract: | To study the resistance to rice blast of rice varieties ever grown in Jilin province, 82 strains of rice blast collected in rice field in Jilin province were inoculated. The results showed that the resistance of newly released varieties was improved greatly. The resistance of "Jiudao 41", "Tongfeng 8" and "Jiudao 33" was superior. Their resistance spectrums were over 95%. The resistance spectrums of other rice varieties were also boosted to a high level, such as "Jiudao 44", "Jiyujing", "Fengxuan 2", "Jiudao 46", "Jiudao 42", "Jiudao 39", "Chaochan 1", "Chaojidao 1", "Tongfeng 8", etc. There was obvious difference in resistance spectrum of the same rice variety to different strains collected from different area. Therefore, rice varieties must be selected properly according to their resistance to local strains. |
