Eight economical Egyptian faba bean (Vicia faba L.) varieties had been evaluated under different drought stress levels and their seed storage protein content patterns under drought stress conditions had been studied and compared with pattern under normal conditions. Analysis of variance of the morphological trait revealed highly significant differences among both treatments and genotypes for the most of studied traits The susceptibility test for drought tolerance revealed that the variety ‘Giza 3’ showed the highest statistical significant susceptibility to drought stress and could be considered as susceptible variety for drought stress, while the variety ‘Giza 843’ was more tolerant to drought stress. Although ‘Giza 3’ variety gave the highest mean across all genotypes for the most of the morphological traits, it was the most drought susceptible variety. On the other hand, ‘Giza843’ gave medium mean across the genotypes but it was the most drought tolerant variety. Negative correlation between the morphological traits and the drought tolerance in faba bean. Using SDS-PAGE analysis, optical differences were obtained between the varieties ‘Giza 843’ (drought tolerant) and ‘Giza 3’ (drought susceptible) in their protein patterns. Many protein bands were obtained in the protein pattern of the variety ‘Giza 843’ that were not obtained in the protein pattern of the variety ‘Giza 3’ while some protein bands were observed in the protein pattern of the variety ‘Giza 3’ that were not present in the protein pattern of the variety ‘Giza 843’. Significant association could be observed between morphological traits and biochemical markers.
