Appropriate selection of donor parent for breeding purposes needs sufficient knowledge about genetic diversity and germplasm classification. In order to investigation and classification of genetic diversity in 35 wheat (Triticum aestivum L.) genotypes, an experiment was conducted in University of Shahed based on randomized complete block design with 2 replications in 2009. In persent study 15 morphological characteristics such as days to 50% of flowering, plant height, number of stems per plant, number of productive tiller, number of internode, length of flag leaf, width of flag leaf, leaves angle, peduncle length, flag leaf distance to spike, spike length, number of grain per spike, awn length, 1000 grain weight and grain yield per plant were evaluated. The analysis of variance for all the traits indicated significant difference between studied genotypes (P<0.01). Range and correlation analysis between traits, showed considerable genetic variation among studied genotypes. Cluster analysis via Ward method for field data, classified all genotypes in four groups. The ANOVA analysis showed significant difference among the clusters for leaves angle. Factors analysis, extract 5 factors that be able to describe nearly %75 of total variance.
