Cold resistance, drought resistance and water and temperature regime of 43 Bulgarian and Turkish winter barley varieties and lines were determined in field and laboratory conditions during the period 2005-2009. 50% of the study material was found to have a good and high resistance to cold. The highest coefficient of drought resistance was found in 9 of the studied lines. Among the tested winter barley varieties and lines those with high and medium cold resistance were found to dominate the study group. The highest biological drought tolerance are Bulgarian lines DRF 206-2 and DRT 279-2 and the Turkish lines AVD-24 and MB-A 51. These lines may be included in the breeding program to create varieties with high resistance to cold and drought resistance.
