Abstract
Rice necrosis mosaic virus was observed in rice cultivarTaichung (Native) 1 at maximum tillering stage. The disease was transmitted by sap and soil.Nephotettix virescens, Nephotettix nigropictus andNilaparvata lugens failed to transmit the disease. Thermal inactivation point, dilution end point and ageingin vitro have been studied. Yield reduction due to this virus varied from 12·7 to 100% on different rice cultivars tested. Disease was more common in upland and directly seeded crop. The virus produced granular x-bodies in inner epidermis of leaf sheath of infected plants.
