Bread Wheat is considered the important winter crop in Egypt and World. Great efforts of wheat breeders and geneticists must be continue to increase the productivity of unit area to face the gap between the production and consumption in Egypt. Increasing wheat production under abiotic stress condition i.e. drought stress has become important during recent years, since wheat production in these areas with optimum growth conditions does not meet the needs of ever increasing population of Egypt. Genetic information regarding important economic characters of wheat under drought stress is required to develop breeding strategies for drought prone areas. So that, this study concentrates on estimating these genetic information under both normal and drought conditions to use these information at breeding program for drought tolerant.
