Abstract Genetic diversity of eight faba bean (Vicia faba L.) varieties was investigated using different types of molecular markers (RAPD, ISSR, SSR, EST, STS) and morphological traits. Both cluster analysis and principal coordinate analysis (PCOORDA) was conducted in order to study the genetic diversity using both morphological traits and molecular markers. The results showed that molecular markers can be used to obtain reliable determination of genetic diversity than morphological traits. Poor correlation (r = 0.32) was obtained between morphological and molecular markers and this problem could be solved by using a lot of morphological characteristics. It can be concluded that both cluster analysis and principal coordinate analysis showed more or less the same results but the principal coordinate analysis give better resolution than cluster analysis in the study of genetic diversity. It can be noted that biochemical markers (seed storage protein content) is efficient marker to study the genetic diversity in faba bean and significant association could be observed between morphological and biochemical markers. The variety ’Giza 843’ seems to be genetically different from the other faba bean varieties and is consider to be drought tolerant variety. On the other hand, ’Giza 3’ variety could be consider as faba bean drought susceptible variety according to all types of markers that have been used in this study (i.e. morphological, biochemical and molecular markers).
