Abbreviation	Fr
Character affected	Cold tolerance
Gene	Fr1 (Triticum) Fr-A2 (Triticum) Fr-B2 (Triticum) Fr2 (Triticum)
Locus	Fr-A2 S2269949 Fr-B2
Comment	Frost tolerance or resistance is the ability of a plant to survive freezing temperatures, and is an important part of winter hardiness. A lack of frost resistance is considered as a major factor limiting cultivation of winter wheat (Wurschum et al., 2017).
