Two hundred and eighty six lines from tetraploid wheat (Triticum turgidum L. var. durum) landrace “SafraMa’an” were selected randomly during 1994-1995 growing season. The entire populations with three commercial check cultivars (Acsad 65, Hourani 27, and Amra) were evaluated at Maru Agriculture Research Station during 1995-1996 growing season for 16 characters including grain yield per plant. The objectives were to assess the magnitude of phenotypic variations for several traits in tetraploid wheat “SafraMa’an” and to evaluate the potential usefulness of some of the traits identified. Results showed wide range of phenotypic variation for most characters. Mono-morphism was common for juvenile growth habit, whereas the rest of the characters exhibited polymorphism in varying degrees. Considering all characters, the average diversity (H) for “SafraMa’an” landrace was 0.65  0.047. There were 10 lines superior to best check (Hourani 27) for grain yield per plant. Subsequently, the population lines were clustered into six distinct groups at a distance of about 0.55 based on their similarity for all traits. Acsad 65 and Amra were located in separate clusters whereas Hourani 27 cultivar was presented in cluster with most lines of “SafraMa’an”. Thirteen lines from the population showed a bluish green cast or glaucousness characters. Glaucous lines have greater kernels per spike. In contrast, this character showed no significant association with grain yield per plant despite the greater grain yield per plant obtained for the glaucous lines. The results are important for the breeding and selection of this crop.
