GrainGenes Gene Report: Fr-B2 (Triticum)

[Submit comment/correction]

Gene	Fr-B2 (Triticum)  [ Marker Report ]
Gene Class	Frost resistance
Locus	Fr-B2
Reference	Toth B et al. (2003) Mapping genes affecting flowering time and frost resistance on chromosome 5B of wheat Theoretical and Applied Genetics 107:509-514.
URL	Fr-B2 gene at Komugi: Catalogue of Gene Symbols for Wheat
Comment	QTL mapped on chromosome 5BL, linked to Xgwm639-5B (this QTL explained 12-31% of the variance in frost tolerance). Xgwm639-5B mapped close to Xmwg914-5B, and to Xbcd508-5B, a marker located at the peak of the Fr-A2 QTL. This data suggests that this locus is more likely orthologous to Fr-2 than to Fr-1 (Toth et al., 2003).
