The grain quality of 38 wheat accessions from different geographic areas has been evaluated. The accessions originated from Eastern Europe have statistical significant higher values of sedimentation value and Pelschenke test than those from Western Europe.
Hierarchical cluster analysis was used to determine the similarity or diversity among the studied accessions. The unique as Lut.1985 H 165 and Albatross Odesskiy (UKR) had high sedimentation value, Pelschenke test and Quality index. The most genetic diverse were the accessions from the third cluster at level 2.5 d.u. The Kansas line SB-140-5 and CLLF/BEZ//SU92/C113645 /3/NAI60/4EMU/5/DYBR 83-6, with high quality -joint breeding of USA / TUR were genetic similar but the most diverse from the others. This gives them priority as suitable genetic material to be included in the effective breading programs for high quality.

Key words: wheat accessions, Pelschenke test, protein, quality index, sedimentation value
