^p.53, "Oryza officinalis from Sukothai, Thailand, is a good source of resistance to several pests and diseases; it has been used in a number of crosses to derive high-yielding lines with multiple pest resistance."
^p.520, "An accession of O. officinalis from Thailand showed high resistance to RTD (62), although it is not yet known whether this resistance is due to resistance to the vector, to the viruses themselves, or to some combination of these resistances. Results from recent research indicate that resistance to RTD is present in many wild rice species (R. Ikeda, personal communication), and perhaps some will show resistance to RTBV."
