Abstract
Barley is an essential crop in the Trakya region and it grows for feed and malting in the region. The experiments were carried out in the 2016-2017 growing cycle and composed of 36 two-rowed and 36 six-rowed barley genotypes in alphalattice blocks with three replications. The characters such as grain yield, net blotch, scald, plant height, days of heading, 1000-kernel weight (TKW), test weight (TW) and protein ratio and relationship among them were investigated in the study. The genotypes were screened for scald and net blotch under natural epidemic conditions. According to the results, there were significant differences among genotypes for the parameters investigated in the study. The means of grain yield for two-rowed and six-rowed genotypes were 8576 kg ha-1 and 8454 kg ha-1 respectively. In two-rowed genotypes mean 1000-kernel weight was 51.2 g, test weight 72.9 kg and protein ratio 11.6%. In six-rowed genotypes mean TKW was 37.0 g, TW 69.5 kg and protein ratio 10.8%. In two-rowed genotypes based on double-digit scores, a total of 11 barley genotypes highly tolerant to Net blotch (Pyrenophora teres) scored between 11 and 33. Net blotch effect on grain yield, 1000-kernel weight, test weight and protein ratio were slightly negative for two-rowed genotypes. Scald leaf disease negatively affected 1000-kernel weight (r=-0.391*) and test weight (r=-0.482**). Scald leaf disease also negatively affected grain yield. In the study, 5 genotypes from the 2-rowed experiments and 2 genotypes from a 6-rowed experiment were selected for breeding studies based on parameters investigated.
