Crop year impacts have been studied in a long-term trial of the Nagygombos experiments of the Szent István University, Gödöllő, Hungary. The present paper is intended to give an overview of 18 winter wheat Triticum aestivum L. varieties tested during the time range between 1996 and 2018. All of the varieties were studied under similar agronomic conditions, each of them for min 3 years in a series of a polyfactorial replicated field trials. The 120 kg.ha-1 N plant nutrition applications of the respective crop years were processed in the evaluation. Amount of grain yield, protein (%), wet gluten and farinographic values of the varieties examined were compared. The results obtained suggest that most of the varieties had a rather high variation concerning yield figures, however protein, and farinographic indicators proved to be more stable characteristics. Wet gluten values were influenced mainly by the crop year. The study supports an evidence that Fusarium graminearum infection of the trials was in accordance with the pre-harvest moisture conditions of a crop year. The study may support a conclusion that certain varieties have shown a higher stability in quality manifestation regardless to the amount of their grain yield. Alföld 90, Jubilejnaja 50, Mv Magdaléna and Mv Toldi varieties proved to be the best quality varieties in this research series.
