5AL |
v:Hobbit,ma:Mapped to the mid-region of 5AL, 2.1 cM distal from Xcdo504-5A and Xwg644-5A and proximal to Xpsr426-5A,ma:Mapped 2 cM proximal to Xwg644-5A and Vrn-A1,ma:and flanked by deletion points 0.67 and 0.68 |
Comment:
Studies using Vrn-1 induced and natural mutants suggest that differences in frost tolerance previously associated to Fr1 are actually pleiotropic effects of Vrn-1 {10708}.

dv:Triticum monococcum. Frost tolerant parent G3116, frost susceptible parent DV92,ma:The QTL mapped on chromosome 5AL had a LOD score of 9 and explained 49% of the variation in frost tolerance. Closest markers: Xbcd508-5A and Xucw90(Cbf3)-5A. These markers are 30 cM proximal to Xwg644-5A, which is closely linked to frost tolerance locus Fr-1. Eleven different Cbf transcription factors were identified at the Fr-A2 locus,ma:QTLs for frost tolerance in the Fr-2 region were also identified in wheat chromosome 5B (Fr-B2 {10079}) and in barley chromosome 5H(Fr-H2 |

ma:QTL mapped on chromosome 5BL, linked to Xgwm639-5B (this QTL explained 12-31% of the variance in frost tolerance) {10075}. Xgwm639-5B mapped close to Xmwg914-5B, and to Xbcd508-5B, a marker located at the peak of the Fr-A2 QTL {10075}. This data suggests that this locus is more likely orthologous to Fr-2 than to Fr-1 |
