This research was conducted in the trial area of Alfa Tohum Ltd.Şti in Gönen district of Balıkesir to determine the heritability of some agricultural characteristics by JinksHayman dialel analysis method on 6 bread wheat (Triticum aestivum L.) varieties. In this study, plant height, spike length, spike number, seed number per spike, seed weight per spike and thousand kernel weight were investigated on parents and F1 plants. As a result of the study, plant height, spike height, seed number per spike and seed weight in spike were dominant, spikelet number/spike and thousand kernel weight were additive and dominant in the traits. According to the results of the Wr-Vr graph drawn on the parents, partial dominance in the 1000 kernel weight and superior dominance in all other characteristics were determined. The highest herritability at narrow and broad sense was estimated as 0,550-0,967 for 1000 kernel weight characteristics. The highest heterosis and heterobeltiosis values were determined as 48.54% - 44.34% in Esperia x Maden hybrid.
