RFLP analysis of resistance to the barley yellow mosaic virus complex

Interaction between Barley Yellow Mosaic Disease-resistance Genes rym1 and rym5, in the Response to BaYMV Strains

“…It was partially and acceptably resistant to BaYMV-III. Chromosomal locations of rym1 (Miyazaki et al 2001) and rym5 (Graner et al 1995, 1999, Miyazaki et al 2001 on RFLP linkage map have been identified. A new (7HS) QTL for BaYMV resistance was also identified in Mokusekko 3 (Miyazaki et al 2001).…”

Screening barley germplasm for resistance to a new isolate of barley yellow mosaic virus (BaYMV)

“…More recently, Graner and Bauer [5] [7]. A new ym5 gene conferring resistance to the new virus BaYMV-2 was also mapped at 1.1 cM of MWG10.…”

“…A new ym5 gene conferring resistance to the new virus BaYMV-2 was also mapped at 1.1 cM of MWG10. Additional crosses like L541 x W122/37.1 (ym5) [7] …”

A CAPS Marker that Distinguishes the Barley Yellow Mosaic Disease Resistance Locus rym1 Derived from Chinese Landrace ‘Mokusekko 3’

“…Konishi et al 10 have indicated that at least two resistance genes, rym1 and rym5, confer resistance to BaYMV in 'Mokusekko 3'. A restriction fragment length polymorphism (RFLP) marker linked to rym5 has already been reported 5,6 as have the location of the rym1 and rym5 loci in 'Mokusekko 3' 11 . Further, Okada et al 14 have reported that the rym1 is completely resistant to BaYMV-I, -II, BaMMV-Ka1 and -Na1 and that it is acceptably resistant to BaYMV-III.…”

“…Several marker systems for identifying Barley Yellow Mosaic disease resistance have been reported 1,2, [4][5][6]8,10,11,15 . However, only one study has developed a selection method for the rym1 locus 11 and this marker system is an RFLP-based marker and, therefore, inadequate for breeders.…”
