Description	The sequences of the closely linked barley dehydrin genes Dhn4 and Dhn7 are both known to vary allelically. Here we associated allelic constitution at Dhn4/7 with frost sensitivity across a panel of diverse barley varieties. The combined presence of a 6bp insertion in exon1 of Dhn4 and a 30bp deletion in exon1 of Dhn7 was restricted to six row winter and intermediate varieties. The alternative combination was present in two row winter and spring varieties. The genetic linkage between Dhn4 and Dhn7 was confirmed by segregation analysis. The potential of the former allelic combination as a marker for enhanced frost tolerance was tested in a sample of F5 derivatives of a cross between the two row winter type variety Monaco and the six row winter type variety Okal. Plants with the Okal allele combination showed significantly higher frost tolerance than those with the alternative type.
