66个水稻品种对稻曲病田间抗性的评价

摘要

The field resistance evaluation of 66 rice cultivars against false smut (Ustilaginoidea virens (Cooke.)Takah) was conducted by the method of natural inducing. The results showed that among the 66 rice cultivars there were 3 cultivars of high resistance,30 resistance, 14 medium resistance, 17 medium susceptivity,1 susceptivity, and 1 high susceptivity.%通过田间自然诱发鉴定了66个中稻品种对稻曲病[病原物为绿核菌(Ustilaginoidea virens(Cooke.)Takah)]的田间抗性水平.结果表明,66个品种中高抗稻曲病的品种只有3个,达到抗级的品种有30个,达中抗级的品种有14个,中感稻曲病的有17个,感稻曲病的有1个,高感稻曲病的1个.
