Abstract

Abstract

To determine the resistance of rice new varieties against rice blast and rice false smut, 101 new rice varieties were evaluated synthetically using the methods of artificial inoculation in the greenhouse and natural infection in the field. The results indicated that rice varieties exhibited the similar resistance under the greenhouse and the field conditions. The results showed that 43 new rice varieties showed middle resistant to rice blast, such as FJSM-25(Yuanyou 2105)、FJSM-26(Yuanyou 919)、FJSM-70(Chunyou 84), 33 new rice varieties showed middle resistant to rice false smut, such as FJSM-21(Lüliangyou 2740)、FJSM-23(Ruiyou 178)、FJSM-24(Yiyou Jia 7). To combinethe both results, 9 rice varieties showed good resistant both to rice blast and rice false smut, such as FJSM-1(Guangyou 1029)、FJSM-11(Tianfengyou 110)、FJSM-25(Yuanyou 2105). Our investigation showed that the occurrence of rice blast and rice false smut on same plants in field is significant high, the frequency of rice varieties co-infected by rice blast and rice false smut were more than 92%.
- new rice varieties (Oryza sativa),
- rice blast (Magnaporthe oryzae),
- rice false smut (Ustilaginoidea virens),
- resistance evaluation
