Enhanced resistance to bacterial blight and blast in IR64 mutant G978-18. a Resistant lines G978-18-8 and G978-18-16 compared with susceptible sister line G978-12-16 and IR64 (wild type) in inoculation tests against ten races of Xanthomonas oryzae pv. oryzae (Xoo) from the Philippines. Lesion length represents mean values of three replications. R resistant, S susceptible. Error bars indicate ±SE. b Disease reaction of G978-18-8, G978-12-16, and IR64 to Xoo strain PXO87 (race 3) and c enhanced resistance to blast isolate, Ca89 in G978-18-8 compared to wild-type IR64. CO39 is a susceptible check.
