  Winter wheat is one of the most popular arable crops in Hungary and worldwide. Its cultivation dates back thousands of years and it is one of the most versatile crops. Its most important role lies in human nutrition, as it is an important staple food for mankind. The global population boom has led to an increasing demand for food raw materials of sufficient quantity and quality. The most important quality parameters for winter wheat are protein content, gluten content, gluten content, starch content and Zeleny index.
  In this comparative genotype experiment, the quality parameters and the relationship between the quantity and quality of winter wheat of different genotypes were investigated in two different rainfall years: a drought year (2021/2022) and a rainfall year (2022/2023). The obtained results show that in the rainy year, the genotypes had significantly higher yield averages and on average higher values for moisture and protein content. Pearson's correlation analysis was used to examine the relationship between the quantity and quality of yield for each genotype in both growing seasons and averaged over the two growing seasons. It was found that quality parameters were negatively correlated with yield quantity when averaged over the two examined years and genotypes.
