This study was carried out during two winter successive seasons 2017/18 and 2018/19 to determine the effect of salinity stress on yield and yield components in F₃ and F₄ segregating populations of the two bread wheat crosses (Sakha 93 x Gemmaiza 9) Cross1 and (Sakha 93 x Giza 168) Cross II. The results showed highly significant differences between means of the two crosses and families for most the traits in F₃, and 100 grain weight in F₄ generations. The differences between salinity levels were highly significant for all traits in both F₃ and F₄ generations. The interaction between crosses × families was highly significant for all traits, except for number of grains/spikes in F₃, while it was highly significant for number of grains per spike and weight of 100 grain in F₄. The interaction between crosses × salinity levels was highly significant for all traits in F₃, while it was highly significant for weight of 100 grain in F₄. As for the interaction between families, salinity levels were highly significant for most traits in F₃, while F₄ were highly significant for weight of 100 grain. The interaction between crosses × families × salinity levels, were highly significant for most traits in F₃, while in F₄ were highly significant for weight of 100 grain. Highest values of H and GA were found for grain yield / plant and weight of 100 grain under salinity conditions in F₄ generation. These traits would be improved by direct selection under saline soil conditions.
