Epidemic characteristics of soybean mosaic virus disease and inheritance of host resistance to SMV G₅-H strain

The epidemic characteristics due to soybean mosaic virus (SMV) on soybean cultivars and the inheritance mode of host resistance to G₅-H strain of SMV were examined. The disease symptoms caused by artificial inoculation with the field collected inoculum of SMV were mosaic symptom which exhibit the crinkling chlorosis in most of cultivars tested, but specifically variety “Kwanggyo” showed necrotic symptom which exhibit veinal necrosis, stem dicoloration and bud necrosis. The mosaic symptoms were recoved considerable degree as the growth stages of soybean are advanced even if in the susceptible cultivars, where as the necrotic symptoms developed more severly. The resistance to G₅-H strain of SMV in the F₁’s and F₂’s which derived form the cross combinations between resistant and susceptible cultivars were considered to be controlled by a single recessive gene.
