Abstract
Three hundred and fourty－eight soybean accessions have been identified for re－sistance to SMV by inoculation with SMV 3,a strong virulent strain in Northeast China.The results showed that 113 accessions were highly resistant to SMV3,account for32.47%.113 accessions were moderately resistant to SMV3,account for 32.47%.122 ac-cessions were susceptible to SMV3,account for 35.06%.Resistant accessions were mainlyoriginated from Northeast China and Huang Huaihai areas.There were few resistant acces-sions from South China in our evaluation.Resistant accessions were mainly from Liaoning,Shandong,Shanxi provinces and Beijing,U.S.and South Korea.Symptoms are differentin different varieties when inoculated with the same SMV strain,showing there are interac-tion between soybean varieties and SMV strains.Top necrosis symptoms were observed inintroduced varieties from abroad,indicating symptoms may relate to geographical origin ofthe accession.Some varieties with known resistance gene introduced from U.S.were identi-fied for the resistance to SMV3 and the relationship of resistance gene between Chinese ac-cessions and U.S.accessions was discussed.关键词
