On the basis of fleshy roots, field-collected, virus-infected plants the sweet potato cultivars Tainung 63 and Okinawa 100 yielded 34.2% and 55.9% less in a nethouse experiment than the healthy control plants derived from shoot tip culture, respectively. Virus-infected plants gave yield reduction of 24.5%, 30.5%, 31.8% and 35.6% for cultivars Tainung 57, Okinawa 100, Hung-hsin-wei and Tainung 63 in the field test, respectively. The dry matter Content, crude protein content and sugar refractometer reading of virusinfected plaits were significantly higher than the healthy control under field conditidns but there were no such differences in the nethouse test for crude protein content and sugar refractometer. No internal corking of fleshy roots was detected in the virus-infected materials used in this study. On the basis of stem and leaf, the virus-Infected plants gave a significantly lower, yield than the healthy under the nethouse condition and the leaf size was also reduced. But in the field test, the yield showed no difference. The dry matter content was increased and crude protein content decreased significantly in infected plants.
