Abstract
In 2005-2007,physiological races of rice blast in Liaoning Province were identified.Monospore strains of pyricularia grisea Saccardo isolated from Liaoning Province were identified by using 7 Chinese different varieties(T).171 monospore strains were divided into 7 groups and 40 physiological races.The tests showed that ZA and ZF were dominant groups in Liaoning Province.In recent years,the occurrence frequency of high virulent races of indica and japonica races increased,and that of low ones were decreased.The races of ZG disappeared in 2006.
