Twenty two winter wheat varieties were tested for the period 2001–2006. The aim was to follow the response of these varieties under various growing conditions with regard to some quality parameters and to determine which of them were able to realize better their quality potential under changeable environments. The varieties were grown by the Latin square design (6 replicates, each of 15 m2). The following characters were examined: test weight (TW), wet gluten content (WGC), sedimentation value (SDS), dough resistance (DRes), valorimeric value (Val) and loaf volume (LVol). The most variable by years (85.4%) is dough resistance and test weight was most stable (2.42%). Aglika, Slaveya and Lazarka varieties showed high stability of each quality index. The new varieties Slaveya and Lazarka possessed very good combination of high quality and high ecological stability and can be therefore considered an excellent breeding achievement in this respect.
