The molecular CAPS-marker was developed which permits to identify the Viviparous-1 gen of Agropyron. The variant of wheat-agropyron hybrid № 209 was revealed, which contain the Viviparous-1 gen from Agropyron. It was shown, that this variant has higher resistance to root sprouting, than other studied variants of wheat-agropyron hybrids. The isolated variant may be used as donor of Viviparous-1 gene of Agropyron for its introgression to soft wheat genome thought suggested molecular marker.
