Abstract
A Chinese landrace of barley, Mokusekko 3, is completely resistant to all the present strains of Barley yellow mosaic virus (BaYMV) and Barley mild mosaic virus (BaMMV), and has at least 2 resistance genes, rym1 and rym5 . However, rym1 has not been used for BaYMV-resistance breeding of barley in Japan so far. In our previous study, rym1 was completely resistant to BaYMV-I, -II, BaMMV-Ka1 and -Na1, and was acceptably resistant to BaYMV-III. Complete resistance of Mokusekko 3 was due to the interaction between rym1 and rym5 . To estimate pyramiding effects of these genes using DNA markers, we investigated the resistance reaction of lines with or without these genes to BaYMV-I and -III. All the pyramiding lines showed complete resistance to BaYMV-I and -III. This study anticipated the resistance to BaYMV-III of Mokusekko 3 by the multiple effect of the rym1 and rym5 genes
