This research aimed to study the impact of modifying the varietal composition of the wheat crop by proposing a varietal map for it, on the economic efficiency of production, the national economy, the most important economic resources and agricultural production requirements. The main results of the research are as follows: The suggested map of wheat varieties leads to an increase in the average productivity of feddan and the total revenue of feddan by about 2.7%. It will also increase the net revenue of the feddan, the return on the water unit by about 11.5% of their average under the current average productivity. It will also lead to an increase in the total production, the total production value, and the self-sufficiency rate of wheat by about 2.7% of the average of each of them under the current average productivity of wheat. Moreover, it will reduce about 2.7% of the economic resources and agricultural production requirements used under the current average productivity of the Feddan. In light of the research findings, it is recommended to: apply the previously mentioned suggested map of wheat varieties in Egypt, work to encourage specialized research centers and institutes to improve the productivity of the wheat crop by raising the productivity of the varieties recommended by the suggested varietal map on the one hand, and producing new varieties that are higher in productivity on the other hand
