摘要
1996～ 1998、1999～ 2 0 0 2年分别采用苗期喷雾接种及穗期注射接种两种鉴定方法对 2 6 4份水稻区试新品种 (组合 )进行了抗稻瘟病性人工接种鉴定 ,共鉴定出抗性材料 74份 ,其中表现高抗的材料 9份 ,表现抗的材料 30份 ,表现中抗的材料 34份 ,分别占总鉴定品种数的 3.4 1%、11.36 %和 12 .88%。
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.
