The results showed that there is a significant relation between yield and plant height (r = 0.786**) in cultivar Yıldırım; number of spike per m2 (r = 0.903**) in cultivar Bülbül-89; spike lenght (r = - 0.506**) in cultivar Yesevi-93; number of grain per spike (r = 0.301**) in cultivar Tarm-92; 1000 kernel weight (r = - 0.838**) in cultivar Obruk-86; protein content (r = 0.275**) in cultivar Yıldırım; winter damage (r = - 0.487) in Tarm-92; cold damage (r = - 0.357**) in Tarm-92.
