Two Point Data
Yr15/Xgwm273
Locus 1
Yr15
Locus 2
Xgwm273-1B
Gene
Yr15 (Triticum)
Gene Class
Reaction to Puccinia striiformis Westend.
Trait marker
Yes
Chromosome
1B
Species
Triticum aestivum
Reference
ReferenceDubcovsky J MAS Wheat. Bringing Genomics to the Wheat Fields. Disease resistance. Stripe Rust Resistance. Yr15 MAS Wheat. Marker Assisted Selection in Wheat.
Remark
Xgwm273-1B is distal to Yr15.
When a translocated alien fragment is in a wild-type Ph1 background it no longer recombines with wheat chromatin (or only at very low frequencies). Therefore, the segment is inherited as a whole, so if there is a molecular marker located within the fragment containing the translocated gene, the genetic distance to the gene would be zero, even when the physical distance could be very large.
