摘要：The present research was carried out to determine water-stress tolerance of malting barley genotypes (Durusu, Firat, Atilir) grown under (winter planting), different water conditions [no water- stress (I_(100)); strong water-stress (I_0)] in the years 2016 and 2017. Variance analyses revealed significant differences between the genotypes (P<0.01). As the average of two years, the greatest yield was obtained from no water-stress x genotype interaction (I_(100)xDurusu) with 5613.50 kg ha~(-1), the lowest yield was obtained from strong water stress x genotype interaction (I_0x Atilir) with 3848.82 kg ha~(-1). Again as the average of two years, the greatest chlorophyll content was obtained from no water- stress x genotype interaction (I_(100)xDurusu) with 45.23 spad, the lowest value was obtained from strong water stress x genotype interaction (I_0x Atilir) with 35.80 spad. The greatest crop water stress index was obtained from strong water stress x genotype interaction (I_0x Atilir) with 0.47, the lowest value was obtained from no water-stress x genotype interaction (I_(100)xDurusu) with 0.24. The lowest protein content was obtained from no water-stress x genotype interaction (I_(00)x Durusu) with 9.36 %, the greatest value was obtained from strong water stress x genotype interaction (I_0xAtilir) with 12.98 %. The Durusu genotype with optimum water use efficiency and prominent with crop water stress index, chlorophyll, chlorophyll content and low protein content both in no water-stress and strong water stress treatments was identified as water stress-resistant and the genotype was considered to have reliable characteristics potentially to be used in further water stress-resistance studies. On teh other hand Atilir (malting barley) genotype was identified as water stress-sensitive. As a result decreased protein content and total protein content in plants under no water-stress treatments.
