    To evaluate the quality of bread wheat produced in farmers' areas around the country, from each 10,000 metric tons of wheat delivered to collection stations or commercial silos, a 3kg sample was taken as per standard sampling method. Each 3 kg sample was divided into 3 samples of 1 kg each. 34 1 sample was locally kept as control at the place of origin and the other two samples were dispatched to Cereal Chemistry and Technology Unit, Cereal Research Department at SPII in Karaj. At the laboratory, one sample was used for laboratory analyses and the other one was kept as control. Wheat quality analyses for 1000 KW, hectoliter weight, moisture content, protein content, protein quality, wet gluten, dry gluten, gluten index, falling number, water absorption and grain hardness were performed according to ICC standard analysis methods. The results indicated that form the total 11.8 million metric tons of wheat purchased in 31 provinces around the country, 69.68% of the samples were highquality, 27.96% were average and 2.35% considered as low quality wheat. In comparison to the previous years in last decade, which the ratio of high quality wheat never exceeded than 25%, this result is indicating a unique rare agronomical event which can be caused by the good climatic conditions , good adaptability of new wheat varieties and good fields managements.
