The field experiment was carried out in the selected area of Pristoe village, Shumen area in the period 2017-2019. The 2test was set by the block-plot design method in four replications with a plot size of 15 m2, after sunflower predecessor. The purpose of the study was to establish the productivity and quality of some common wheat varieties, grown in North-Eastern Bulgarian region. The varieties 'Avenue’ 'Joker’ 'Apache’ and 'Neven’ were tested. The indices; length of spike (cm), number of spikelets per spike number of grains per spike, grain yield (kg/ha), thousand kernel (grain) weight (g), test weight (kg), vitreousness (%), wet gluten content (%), gluten deformation index (mm) were reported. The results showed that the highest grain yield was obtained from Avenue variety - 7900 kg/ha, followed by Joker - 7400 kg/ha and the lowest one - from Neven variety 6600 kg/ha. The highest values of test weight and the vitreousness content was reported for Neven (84.7 kg and 89.6%) respectively. Joker variety show the best values of the investigated technological properties of the grain among the tested varieties wheat.
