摘要

Resistance of 17 major rice cultivars in Hangzhou region of China against southern rice black-streaked dwarf virus was tested in the paper. The results showed that the incidence rate of southern rice black-streaked dwarf virus had certain positive correlation with quantity of white-backed planthopper (Sogatella furcifera) and resistance among various cultivars was significant. Two varieties, Yueyou 9113 and Tianyouhuazhan, were most susceptible; Yongyou 8, Jiayou 2 and Xiushui 134 had best resistance and could be used as disease-resistant varieties to prevent the disease.
