Abstract
Two doubled haploid rice populations derived from the F1 hybrids IR64/Azucena and IRAT177/Apuraj, and segregating for many agronomic traits, were used to map resistance genes to rice yellow mottle sobemovirus (RYMV) and blast (caused by Magnaporthe grisea). For the IR64/Azucena population, interval mapping revealed one locus associated with significant effects in RYMV resistance on chromosome 12. Significant resistance loci identified in the IR64/Azucena population are tabulated. Some loci were strain specific and others were common to different strains.
