BGS 141, Reaction to barley yellow mosaic virus 5 (BaYMV), rym5
Stock number: BGS 141
Locus name: Reaction to barley yellow mosaic virus 5 (BaYMV)
Locus symbol: rym5
Previous nomenclature and gene symbolization:
Resistance to BaYMV = Ym (3, 5, 7).
Resistance to BaYMV 5 = ym5 (4).
Resistance to BaYMV 5 = rym5 (8).
Inheritance:
Monofactorial recessive (4).
Located in chromosome 3HL (7); rym5.h is approximately 2.5 cM distal from the Est1 (Esterase 1) locus (4, 7); flanked by molecular markers MWG838 and MWG010A at distances of 0.8 and 1.3 cM, respectively, in 3H bin 16 (1).
Description:
Plants with the rym5.h allele are resistant to Japanese strains I and II of BaYMV, but susceptible to Japanese strain III of BaYMV (2). In Germany, plants with rym5.h are resistant to strains BaYMV-1 and BaYMV-2 (6, 10). Although plants with rym5.h are resistant to BaMMV (barley mild mosaic virus) in Germany (6, 10), they are susceptible to the Japanese strain BaMMV-Na (6, 9).

Mutant used for description and seed stocks:
rym5.h in Misato Golden (OUJ848) from Mokusekko 3 (4).
