Title: Nucleic acid markers for rice blast resistance genes and rice blast resistance genes isolated by the use of these markers

Abstract: The present invention provides nucleic acid markers for rice blast resistance genes Pi-ta and Pi-ta.sup.2, which hybridize with any RFLP probes isolated from rice genomic DNA and are located within a distance of 2.0 cM from rice blast resistance genes Pi-ta or Pi-ta.sup.2. According to the present invention, it becomes possible to easily identify rice blast resistance genes and related genes from rice cultivars containing Pi-ta or Pi-ta.sup.2, thus promoting development and breeding of superior cultivars. It becomes also possible to easily carry out a resistance test of rice. This will open up way to create new resistance genes.
