Water deficits and high air temperatures occur frequently in southeastern Europe, especially at the grain filling period of winter and spring malting barley. The objective of this paper was to study the grain and malt properties of 32 two-rowed winter and 32 two-rowed spring barley genotypes under moderate and severe drought conditions during grain filling. In moderate drought conditions, spring barley produced 28% lower yields than winter barley and had better mechanical grain characteristics, 2% less grain protein and 3.22% more fine extract. In severe drought conditions, winter barley had yields that were almost two and a half times higher than those of spring barley as well as better mechanical grain characteristics, a lower grain protein content and a higher fine extract content. In agroecological conditions in which stresses caused by drought and high temperatures are possible, both forms of malting barley, winter and spring, should be grown.
