The presented work provides the results of experiments with winter wheat during the growing season 2016/2017, which were established at the field research station of Mendel University in Žabčice. Eight winter wheat varieties were grown on two sites with different water regimes in the soil (optimal conditions - Obora/water-limited conditions - Písky). The varieties were evaluated for the number of spikes per area, thousand seed weight and grain number per spike. Then the grain yield per hectare and harvest index (which was calculated as the ratio of biomass and grain) were evaluated. In the water-limited conditions, there was a decrease in all monitored characters. The site had the largest influence on the number of spikes per area where the average number of spikes per area under water-limited conditions fell by 23 %. The second most affected was thousand seed weight which was decreased by 19 %, and the least affected character was grain number per spike, which was changed by 11 %. The harvest index was lower on water-limited field. The weight of biomass was reduced by 24 – 34 % and weight of grain was reduced by 50 % for evaluated varieties. The average yield at the site with optimal conditions was 10,4 t per ha and at water-limited conditions site it was 6,1 t per ha. According to the results of this harvest year 2017 varieties Patras, Gordian and Cimrmanova raná were found as suitable for worse conditions. On the other hand varieties Tobak and Hyfi seem to be unsuitable for stressful conditions.
