Резюме
Breeding lines from durum wheat (Triticum durum Desf.) with increased cold tolerance
are produced by the screening method. Cold tolerance is impeded in 3 consecutive years at
different conditions on hardening and temperature regimes of freezing. It is compared with
cold tolerance of some cultivars of durum wheat and common wheat. The cold tolerance of
the studied screening lines is also compared to check varieties of the specific scale used to
winter wheat cultivars.
