According to combined variance analysis statistically significant differences (P<0.05 or P<0.01) were determined for all examined traits of genotypes in two years. According to results of analysis G21 in first year and G5 in second year had a highest grain yield. G4, G8 and G5 (Dinç) were determined as higher yielding genotypes, also they showed similar performance for both two years, while G19 and G21 had a high yield but different peformance, so they could be suitable for specific areas. Results indicated that G9 was the best for 1000 kernel weight and test weight and G21, G3, G4 were the best genotypes for grain yield, sedimentation, protein content respectively in the first year; G14, G12 and G15 were classified as best for grain weight in spike, sedimentation and 1000 kernel weight respectively in second year. Positive and high correlation were determined between number of spike in square meter and grain yield; also between protein content and sedimentation; negative correlation between grain yield and protein content. According to results of present study, G21 was determined as candidate for registration as cultivar because of it`s high grain and appreciate quality traits, also number of spike in square meter could be used as parameter to select high yielding genotypes in breeding programs.
