| Abstract: | Two hundred and sixty-four new rice varieties were tested to identify resistance to the blast by using two kinds of inoculation methods from 1996 to 1998 and 1999 to 2002. There were 74 rice varieties showing resistance to Pyricularia oryzae. Among of them, nine rice varieties showed high resistance to the pathogen, thirty were resistance and thirty-five showed intermediate resistance. The proportion of resistant varieties in difference type was respectively 3.41%, 11.36% and 12.88% among total rice varieties. |
