Progress of rice resistance research in China was reviewed in the study based on exploitation of wild rice, breeding of hybrid rice, new resistant rice variety, stress resistance gene, relation between hormone and rice resistance, effects of Si and Ca on yield increase, providing reference for research of rice yield improvement.
CO39, its near_isogenic lines, having single blast resistance gene, C101LAC, C101A51, C104PKT, and C101PKT, and its resistance gene pyramid lines BL121, BL241, and A57_119, grew in the blast nursery at IRRI. The seeds...

CO39, its near_isogenic lines, having single blast resistance gene, C101LAC, C101A51, C104PKT, and C101PKT, and its resistance gene pyramid lines BL121, BL241, and A57_119, grew in the blast nursery at IRRI. The seeds were sown in four batches with two weeks interval between batches, using IR50 and IR72 as spread rows and susceptible controls. For moist leaf, spraying water was proceeded every two hours from 8:30 am in sunny days. Blast disease was scored and pathogen was isolated every two weeks. DNA samples of 310 isolates were used for diversity analysis by Pot 2_based PCR (Pot 2, a dispersed retrotransposon of the fungus).
