Abstract:

The natural identification of Shanghang Fujian to a representative of the 162 seedlings in field blast materials, leaf blast and panicle blast incidence survey, overall performance of Shanghang Fujian for the identification of resistance in more than 62 anti-material recovery system indoor seedling identification of different strains, 27 high resistance to the blast resistance of rice restorer lines with high generation of materials. Survey results showed that the seedling blast, leaf blast and panicle blast incidence rate was 3.01%, 12.42% and 26.21%, seedling blast and leaf blast, seedling blast and neck blast, leaf blast and panicle blast incidence correlation 0.69,0.67 and 0.78, respectively, have reached a significant level. Panicle blast incidence was significantly greater than the seedling blast and leaf blast and panicle blast incidence at different times higher. Grade 4-5 plague vaccine, later identified neck blast is likely to be susceptible or highly susceptible; In this study, identification of panicle blast to susceptible or highly susceptible, seedlings or leaf blast blast identified generally susceptible or high feeling. Key words: Hybrid rice restorer line rice blast resistance
