Combining ability and genetic components of six soybean parents and their F₁ and F₂ half-diallel crosses were measured in Etay El-Baroud Agriculture Research Station during 2017, 2018 and 2019. mean square due to genotypes; parents, crosses and parent vs. crosses were significant for all studied traits in both generations, except parent vs. crosses for protein and oil contents in F₁ and both number of seeds/pod and 100-seed weight in F₂. Mean squares due to general and specific combining ability were significant for all studied traits in F₁ and F₂, except SCA for number of seeds/pod in F₂. The ratios of GCA/SCA were higher than the unit for all studied traits in both F₁ and F₂ generations. Mean squares due to additive (a) and dominance (b) components were significant for all studied traits in both F₁ and F₂. The two parents Dr101 and Giza111 and the three crosses Giza111 x Giza83, Dr101 x Giza83 and Dr101 x Giza111 gave the highest seed yield/plant. Dr101 expressed negative ĝ_i effect for maturity period and positive ĝi effect for most yield traits in both generations. The cross combinations of Giza111 and Dr101 with Giza83 had the significant positive Ŝ_ij effect for seed yield/plant in both F₁ and F₂. The additive genetic variance (D), dominance genetic variations (H1) and (H2) were highly significant for all traits in both F₁ and F₂ hybrids except additive type for number of seeds/pod in F₁. Pedigree method consider an excellent method to select superior lines in the early segregated.
