Quality and quantity of winter wheat varieties in 22 years’ time range
Keywords:wheat, quality, quantity, long term trial
The Nagygombos experiments of the Szent István University, Gödöllo ̋, Hungary have always been a testing area for various agronomic technologies as well as a research site for evaluating the performance of crop varieties. 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 trial. The 120 kg/ha N plant nutrition applications of the respective crop years were processed in the evaluation. Amount of grain yield, protein %, wet gluten content 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 content was influenced mainly by the crop year. The study may support a conclusion that certain varieties have shown a higher stability in technological quality manifestation regardless to the amount of their grain yield. Alföld 90, Yubileynaya 50, Mv Magdaléna and Mv Toldi varieties proved to be the best quality varieties in this research series.
