A half diallel cross among seven parents of wheat (Triticum aestivum, L) was carried out at Etay El-Baroud Agricultural Research Station in El-Behira governorate during the three successive seasons 2012/13, 2013/14 and 2014/15 growing seasons in randomized complete block design (RCBD) with three replications. Data were recorded for F1 and F2 generations for grain yield /plant (g), number of spikes /plant, number of grains/spike, 1000-grain weight (g), straw yield /plant (g), biological yield /plant (g) and harvest index (%). Mean squares for genotypes, parents, crosses and parent vs. crosses were significant for all the studied traits for F1 and F2 generations. General combining ability (GCA) and specific combining ability (SCA) mean squares were significant for all the studied traits in both generations. GCA/SCA ratios were largely exceeded the unity for all the studied traits in both generations. Wheat cultivar Sids 12 (P1) showed the maximum desirable GCA values for number of grains / spike and 1000-grain weight (g) in both generations. The parent line 1 (P6) followed by Sham 6 (P5) proved to be good combiners for grain yield /plant, straw yield /plant and biological yield /plant. The parent Line 2 (P7) proved to be the best  combiner for number of spikes /plant and harvest index. (Sahel 1 x Line  2) cross showed the maximum desirable SCA values for straw yield /plant and harvest index in F1 generation. As well as, for biological yield /plant in both F1 and F2 generations.  (Gemmeiza 11 x Line 2) cross showed the best SCA for grain yield /plant and harvest index in F2 generation. ( Gemmeiza 11 x Sham 6) cross gave the maximum SCA for number of spikes /plant and straw yield /plant in F2 generation. (Sids 12 x line 1) cross expressed the highest SCA for grain yield/plant and number of spikes /plant in F1 generation. (Sids 12 x Sahel 1) cross showed the maximum number of spikes /plant in F1 generation. For 1000-grain weight, (Sham 6 x line 1) and (Gemmeiza 11 x line 1) crosses gave the highest SCA in F1 and F2 generations, respectively.
