It was investigated the responses of BaYMV resistant genes to Korean BaYMV(Barley yellow mosaic virus) strains. BaYMV was distributed dominantly with about 51% detection ratio among the three investigated virus such as BaYMV, BaMMV(Barley mild mosaic virus) and SBWMV(Soil-borne wheat mosaic virus) in ELISA test. Double infection with BaYMV and BaMMV was detected also higher as 38.8%, however, BaMMV sole infection ratio was lower with only 1.4%. The 11 BaYMV resistant genes were tested their responses to four Korean BaYMV strains, BaYMV-N, H, I and M. Generally, rym 3 genes showed resistant to Korean BaYMV strains and rym 4m and 5a also was better. Three genes, rym 1+5(Mokusekko-3), rym 3(Ea 52, Baitori) and rym 5a(Solan) showed resistant responses to BaYMV-N type. In -H strain test, seven genes that rym 2(Mihori Hadaka 3), rym 3(Ea 52, Haganemugi, Baitori), rym 4m(Diana, Franka), rym 5a(Solan), rym 7(Hor 3365), rym 9(Bulgarian 347), rym 12(Jochiwon Covered 2) were considered as resistant. The three genes that rym 1+5, rym 3 and rym 5a was effective to -I strain, and rym 3, rym 4m and rym 5a showed resistant to -M strain.
