The inheritance of plant height, tiller number per plant, spike height and 1000-kernel weight was studied using a Jinks-Hayman diallel analysis in a 8×8 wheat (Triticum aestivum L.) cross population with the following bread wheat cultivars: Cumhuriyet (1), Kasifbey (2), Ziyabey (3), Marmara (4), Basribey (5), Malabadi (6), Yüregir (7) and Seri-82 (8). The data analysis showed that the additive variance component (D) was significant for plant height, spike height and 1000-kernel weight at 1% level. The F parameter which is effect of dominant and recessive genes has a positive value for all four traits studied and was significant for plant height at 1% level. Dominance variance component (H1), corrected dominance variance component (H2) and dominancy level variance component (h2) were significant for all four traits studied. The Wr-Vr graphs indicated overdominance can be inferred for tiller number number per plant, spike height and 1000-kernel weight while partial dominance could be inferred for plant height.
