Abstract: During the period 2008 – 2010, on the plot of land with Сinnamonic Forest soil in the Agricultural Experimental Station of Irrigative Agricultute, Pazardzhik, a field experiment was set after the block method in four replications. We tested the productive capacity of 14 wheat varieties selected in three regions of the country – Sadovo, General Toshevo and Karnobat. The aim of this study was to determine which varieties can be easily adapted to the conditions of the Upper Thracian Plain. The three-year study showed that the meteorological conditions and, most of all, the rainfalls have the most significant impact on the productivity of the varieties. In the first year we had the highest grain yield, the highest absolute and hectoliter weight of all varieties. On average for a period of three years the highest yield was obtained from Todora 671 kg/da, followed by Bolyarka 611 kg/da, Miryana – 600 kg/da, Geya 1 – 583 kg/da and Prelom – 570 kg/da.
