Quality traits in winter wheat: Comparison of stability parameters and correlations between traits regarding their stability

Fluctuations of environmental conditions increase variability in both grain yield and quality of wheat (Triticum aestivum L.). In order to evaluate stability, different stability parameters of the static or the dynamic concept can be applied, which could be negatively correlated. While correlation analysis of the mean performance between traits is common, correlations between stability estimates for quality traits have not been investigated, to the best of the authors’ knowledge. Therefore, indirect, rheological and baking traits, and grain yield from two datasets were analysed, and the mean performance, each three stability parameters of the two different concepts (static and dynamic) were calculated over all environments within each dataset.
