Abstract :In this study, it was aimed to calculate the harmonization ratio before and after the flowering period (GFPtt/VPtt) in barley depending on thermal times, to determine the vegetative period (VP) and grain filling period (GFP) values for higher grain yield (GY) capacity and the possibility of using these qualities as adaptation and selection criteria and to determine the relationship between HR and GY calculated according to phenological periods depending on thermal times under Kahramanmaraş conditions. The experiments were carried out in Kahramanmaraş, located in the Eastern Mediterranean Region of Turkey, between 2014 and 2016 under the conditions of 9 genotypes for 2 successive years according to the randomized completed block design with 3 replicates. Phenological traits such as VP, GFP, GY and days to maturity (DM) were measured in relation to thermal times. According to the results, genotypes were found to be significantly different in terms of harmonization ratio in barley. Considering the two-year averages, the highest grain yields were determined as Samyeli (534.3 kg da-1) and Şahin-91 (532.8 kg da-1). The lowest grain yields were determined as Kendal (404.9 kg da-1) and Sur-93 (416.9 kg da-1). According to the results, barley genotypes were found to be significantly different in terms of harmonization ratio. The highest harmonization ratios were determined as Samyeli (0.753) and Kendal (0.672), the lowest harmonization ratios were determined as Şahin-91 (0.486) and Athena*Yabani (0.558). Although there was a general relationship between grain yield and harmonization ratio, some genotypes had values outside this trend.
