| Abstract | ||||
| Nine faba bean genotypes have been selected under different drought stress conditions throughout faba bean breeding program at Fs generation. These genotypes were evaluated comparing with the commercial cullivar Giza-461 at Fs generation for the performance of yield and its components and genetically verify for drought tolerance. The obtained results from the green house experiment indicated that genotypes no.,4 , 5 and 7 gave the highest values for yield and its components. Moreover, the biochemecal genelic results verify that the genotypes no.4,5,7.8 and 9 gave the highest values for isozyme activities, either for isozymes accompanied with yield and its components or those associated with drought tolerance. Also, the results of isozyme banding patterns showed thai genolypes no., 4 and 5 gave the highest gene expression for the genes associated with both drought or yield and its components. Generally, it could be concluded that genotypes no., 4 and 5 were the best genotypes of faba bean breeding program. where gave the maximal productivity under drought conditions. | ||||
