Evaluation of Resistance in Soybeans to Soybean Mosaic Virus Strains1

  1. Eui Kyoo Cho and
  2. Robert M. Goodman2



Virulent strains of soybean mosaic virus (SMV) cause a severe necrotic disease in soybeans [Glycine max (L.) Merr.] possessing resistance to less virulent SMV strains. Forty-six soybean cultivars or lines thought to possesss resistance to at least one SMV isolate were tested for reactions to seven SMV strains. Five lines developed in Korea (Suweon 86, Suweon 94, Suweon 95, Suweon 97, and Suweon 106) were immune to all seven SMV strains. The other accessions tested produced either systemic necrosis or mosaic symptoms in response to infection with one or more of the virus strains; 28 of these possessed resistance to some but not all strains.
