The purpose of the study is to investigate four winter wheat cultivars (Triticum aestivum L.). The areas were found to be heavily weeded with Lamb’s (Chenopodium album), Amaranth (Amaranthus retroflexus L.), Field mustard (Sinapis arvensis L.) and Wild oats (Avena fatua L.). The studied cultivars are characterized by good productivity as the average yield for the group is 773.7 kg/da. Avenue cultivar showed the highest grain yield - 861 kg/da. It was found that the tested cultivars are characterized by good baking qualities. The average wet gluten content is 27.6%. It has been found that foreign cultivars are significantly attacked by Powdery mildew (Erysiphe graminis De candolle), Brown (Puccinia recondita Rob. Et Desm. f. sp. tritici) and wheat stripe (yellow) rust (Puccinia striiformis West.) and Septoria tritici leaf bloth (Septoria tritici Rob. ax Desm.).
