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 (Dhillon et al., 2010)
Fr1 mapped to the mid-region of 5AL, 2.1 cM distal from Xcdo504-5A and Xwg644-5A and proximal to Xpsr426-5A (Galiba et al., 1995) and 2 cM proximal to Xwg644-5A and Vrn-A1 (Snape et al., 1997). Fr1 was flanked by deletion points 0.67 and 0.68 (Sutka et al., 1999).
