Abstract :The crosses between three bread wheat cultivars and 10 lines insert ignore into journalissuearticles values( 30 hybrid combinations ); were made by line x tester method to determine the bread wheat crsosses and parents with high quality for Central Anatolian Condition .Crude protein and gluten contents, sedimentation values were measured in all parents and their hybrid grogenies. General and specific combining ability, heterosis and heterobeltiosis, broad and narrow sense heritability of parents and crosses were calculated by using the line x tester method. Non-additive gene affects and low narrow sense herita-bility degress were estimated for crude protein, and gluten contents and sedimentation values of grain.The average values of heterosis for all characteristics were positive ,while the average values of heterobeltiosis for all characteris-tics were negative . As a result suitable combinations and parents to be used in quality breeding in bread wheat were determined.Based on tree carastarictic since 2, 5 and 7 nubbered lines with kıraç 66 variety had possitive and signifi-cant GKY variance these can be recmmended in quality breeding programmes for breadwheats
