Reciprocal crosses were made between seven different hexaploid wheat varieties. F1 hybrids and their parents were grown in a semi controlled green house in a randomized block design with two replications. General and specific combining abilities and general and specific reciprocal effects were determined for sodium dodecyl sulfate sedimentation test (SDS), percentage of grain protein, grain protein and non protein content per spike, 1000 grain weight and grain weight per spike. Genetic variability and significant general combining abilities were observed for all the studied traits except percentage of grain protein. Specific combining ability and heterosis in F1 hybrids when compared with the best parent presented some significant cases in all studied traits. General reciprocal effect was significant only for sodium dodecyl sedimentation (SDS) and specific reciprocal effect for SDS and 1000 grain weight. Regarding combining abilities results the cross between "Qualital" and "Capet" was proposed for breeding
