"Giallume" is a disease of rice caused by the rice giallume virus (RGV), a nonspecific strain of the barley yellow dwarf virus. The study of the inheritance of resistance to giallume in rice (Oriza sativa L.) was carried out on the basis of two susceptible/resistant crosses. The test plants, artificially inoculated at the first-leaf stage using the aphid Rhopalosiphum padi (L.) as vector, were classified on the basis of symptom expression. It was impossible, under the conditions of this experiment, to clearly identify the heterozygotes. The data agree with the hypothesis of one incompletely dominant gene governing resistance.
