Mokusekko 3, a Chinese landrace, is an important genetic resource for resistance to Barley Yellow Mosaic Virus (BaYMV). Using this genotype as a cross parent, the resistant varieties including Misato Golden were developed. Misato Golden carries one partial dominant resistance gene (Ym) which is tightly linked to the esterase-isozyme-geneblock Est1-Est2-Est4 on chromosome 3, as found previously in hybrid populations (KONISHI et al. 1989). Whereas, in Mokusekko 3, another gene(s) in addition to Ym is responsible for resistance to BaYMV, which is related to the marker gene K for hooded lemma on chromosome 4.
