The Rostov region is the northern area of winter barley cultivation in the SFT, that explains the deviations of its sowing areas during the years. Therefore, the development of more frost resistant cultivars is of great importance today, and their implementation into production will allow stabilizing the amount of harvesting areas under the crop. Thus the article gives the results of assessment of frost resistance and intensity of early spring germination of collection samples of winter barley in the Azov-Blacksea Engineering Institute (Zernograd). The samples of the world collection of ARRIR (Saint-Petersburg) and new varieties and lines of research institutions of the south of Russia were used for the study as initial material. The trial assessment on frost resistance and intensity of early spring germination of winter barley was received in 2011 and 2012, when the temperature on the depth of the nods was 12-130 С below zero. It has been determined that on average during the years of study the varieties and lines of domestic breeding possessed high frost resistance and rapid rates of early spring germination. These are the cultivars of Krasnodar RIA (‘Radikal’, ‘Bastion’, ‘Samson’, ‘Line 385-1’ and ‘Line 388-2’), of All-Russian RI of grain crops (‘Tigr’, ‘Zhiguli’, ‘Larets’) and of Stavropol RI (‘Andryusha’). The cultivars ‘Tsiklon’, ‘Vavilon’, ‘Sekret’, ‘Mikhaylo’, ‘Rubezh’ (KRIA), ‘Timofey’, ‘Polet’ (ARRIGC), NB 03435 (US) and SGL-97/04/05 (Czechia). These samples are widely used in hybridization to develop frost resistant varieties with high regenerative ability.
