Results of four-year studies of winter soft wheat (Triticum aestivum) of Western Europe breeding varieties and variety samples from Poland (STH-48, STH-393, STH-703, Symfonia, Elena, Sakva and Cobra), Hungary (MV-Palma, MV-Vilma), Germany (Tsentos), Sweden (Ragnal), Belarus (Kapylyanka – control standard variety) for yielding capacity and fungal disease resistance indices realized in the conditions of the Republic of Belarus were presented. The realized studies showed that in the conditions of Western region of the Republic of Belarus on wheat seedlings there was stated the development of powdery mildew (Erysiphe graminis), brown rust (Puccinia triticina) and root rots (in the majority of cases of Fusarium aetiology). Intensity of disease manifestation varied in all studied varieties. Among the varieties and variety samples of foreign breeding there were selected samples exceeding the control standard samples by the following agronomic characters: winter hardiness, cold resistance, lodging resistance, yielding capacity elements and crude gluten content in grains. Research results proved that all European samples did not show high indices of cold resistance. The highest yields and stability were typical for Sakva and VM-Vilma varieties. The highest productivity indices were stated for the following varieties: Syria (Sweden) – quantity of grain per head – 42,1 pcs., grain weight – 1,7 g; MV-Vilma – head length – 9,8 cm, grain quantity per head – 42,3 pcs, grain weight per head – 1,8 g. The highest crude gluten was stated for Sakva variety (38,7%)
