Abstract :In this study, the inheritance of various yield traits in the population of 4x4 full diallel crosses of one variety (Cakmak-79) and the three local populations (Ahmet, Dallı and İri) in durum wheat were investigated.In this research; plant height, spike length, spikelet number per spike, kernel number per spike, kernel weight per spike and grain yield per plant were observed in all parents and their hybrid progenies. Additive gene actions were found to be significant for spike length, while both additive and non-additive gene action was determined to be significant for plant height, spikelet number per spike and kernel number per spike, non-additive gene actions were found to be significant for kernel weight per spike and grain yield per plant. GCA effects were obtained to be significant for kernel number per spike, kernel weight per spike and grain yield per plant in Çakmak-79 cultivar, for plant height, spike length, spikelet number per spike, kernel number per spike and kernel weight per spike in Dallı wheat and for plant height and spike length in İri wheat. The hybrid combinations which had significant heterosis and heterobetiosis effects were found for all traits observed. Narrow-sense heritability value ranged from 0.17 and 0.61 for all traits while spike length had the highest narrow-sense heritability value (0.80).Keywords : Diallel analiz, makarnalık buğday, verim özellikleri, GKK, ÖKK, resiprokal etki, kalıtım derecesi, heterosis, heterobel-tiosis
