Abstract :In this study , the crosses by using diallel method between six bread wheat cultivars were made in 2000 growing season in Konya in order to determine suitable bread wheat. Parents and crosses and to obtain heritability and of yield and yield compo-nents. The crosses and parents were grown in 2001-2002 growing season. Plant height, spike lenght, number of spikelet per spike, kernel number per spike, grain weight per spike were measured, counted, weighted and analysed in all parents and their hybrid progenies. On each observed characters, general and specific combining ability, heterosis and heterobeltiosis, broad and narrow sense heritability of parent and crosses were caculated by using diallel method. Correlations between characteris-tics were obtained. Both additive and non additive gene effects were estimated for spike lenght non additive gene effects and low narrow sense heritability degrees were determinated for grain weight per spike. Gün-91 was obtained suitable parents for spike lenght, grain weight per spike, number of spikelet per spike, kernel number per spike and short length.
