PURPOSE: To obtain the subject nucleic acid marker hybridizing with either one of specific RFLP probes, positioned at a prescribed distance from a rice blast resistant gene Pi-ta, etc., effective for promoting the development and breeding of superior species, facilitating the resistance test of rice plant and useful as genetic resource, etc. ;CONSTITUTION: This nucleic acid marker is hybridizable with either one of RELP probes separated from the genom DNA of rice, e.g. XNpb289, XNpb196, XNpb319, XNpb239-1, XNpb154, XNpb88, XNpb26l, RUBss and XNpb3l6 and positioned at a distance of ≤2.0 centi-Morgan (CM) from rice blast resistance gene Pi-ta or Pi-ta2.;COPYRIGHT: (C)1995,JPO
