Genotyping of 10 blast resistance genes,which were cloned from 22 leading rice cultivars or new bred rice strains grown mainly in Shanghai,was carried out by using molecular marker detection technology for clearing these genes' distribution in the 22 rice cultivars or strains. The results showed that 22 rice cultivars or strains all contained rice blast resistance genes <i>Pi 36</i>、<i>Pi 37</i>、<i>Pi-d 2</i> and <i>Pib</i>,while the distributions of <i>Pi-k</i>^<i>h</i>、<i>Pi 9</i>、<i>Pi 2</i>、<i>Pi-ta</i> and <i>Pikm</i> were different in above different rice cultivars or strains. And all the rice samples detected did not contain <i>Pi 25</i>.
