摘要: 采用室内人工注射接种法和田间自然诱发法评价福建省15个水稻新品种对稻曲病和穗瘟病的抗性。水稻品种对稻曲病的室内抗性评价结果表明,有3个水稻品种对稻曲病表现为中抗,如FJZD10-5、FJZD10-8,有4个品种表现为中感,8个品种表现为感病。水稻品种对稻曲病的田间抗性评价结果表明,有11个品种表现为中抗,如FJZD10-2、FJZD10-3,有4个品种表现为中感。水稻品种对穗瘟病的田间抗性评价结果表明,有7个品种表现为中抗,如FJZD10-6、FJZD10-7,4个品种表现为中感,4个品种表现为感病。在建阳、宁化和福安3个田间试验点,同时发生稻曲病和穗瘟病的水稻品种出现的频率分别为100%、73.33%和73.33%。未出现对稻曲病和稻瘟病均表现为抗病的水稻品种。

Abstract: The resistance evaluation of 15 rice new varieties to rice false smut and rice neck blast disease was tested in Fujian Province by using methods of artificial injected inoculation in greenhouse and natural inducing in field, respectively. The evaluation results of rice resistance to false smut in greenhouse showed that 3 varieties were middle resistance (MR), such as ‘FJZD10-5’,‘FJZD10-8’, 4 varieties for middle sensibility (MS) and 8 varieties for sensibility (S). However, the results of rice resistance to false smut in field showed 11 varieties for middle resistance (MR), such as ‘FJZD10-2’,‘FJZD10-3’, and 4 varieties for middle sensibility (MS). The evaluation results of rice resistance to neck blast in field showed that 7 varieties were middle resistance (MR), such as ‘FJZD10-6’,‘FJZD10-7’, and 4 varieties for middle sensibility(MS) and 4 varieties for sensibility (S). The frequency of rice varieties co-infected by rice false smut and neck blast in tested field of Jianyang,Ninghua and Fu'an were 100%, 73.33% and 73.33% respectively. Among the 15 rice varieties, no any variety showed resistance to both rice false smut and neck blast disease.

Key words: rice (Oryza sativa), rice false smut (Ustilaginoidea virens), rice neck blast(Magnaporthe grisea), resistance evaluation
