Estimating the term…
The present invention provides nucleic acid markers for rice blast resistance genes, which are isolated from the rice genomic DNA, are DNA sequences having a total length of up to 2 kb, with two identical sequences of at least ten bases at the both ends thereof and are located within a distance of 2.0 cM from rice blast resistance genes Pi-b, Pi-ta or Pi-ta.sup.2 . According to the present invention, it becomes possible to easily isolate rice blast resistance genes and related genes from rice cultivars containing Pi-b, Pi-ta.sup.2 or Pi-ta, 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 the way to create new resistance genes.
A nucleic acid marker for rice blast resistance gene Pi-b, which is:
A nucleic acid marker from rice blast resistance gene Pi-ta.sup.2 or Pi-ta.sup.2 , which is:
