Data : Breeding progress for pathogen resistance is a second major driver for yield increase in German winter wheat at contrasting N levels

This is the experimental data set of Zetzsche, et. al. (2020, Scientific Reports: doi.org/10.1038/s41598-020-77200-0 based on a three-year field trial (2014/15, 2015/16, 2016/7) of 178 German elite winter wheat cultivars. The table (QLB_BRIWECS_WW_fieldtrial_adjustMeans_treatments.csv) subsumes the adjusted mean values of four fungal disease scores (average ordinates) and six yield-related traits investigated at four treatments (T1: 110 kg N ha-1, no fungicides; T2: 110 kg N ha-1 + fungicide; T3: 220 kg N ha-1, no fungicides; T4: 220 kg N ha-1 + fungicide) of two replicates each over three years. Data of each trait are considered independent for all four treatments. Details of the plant material, the experimental site, the trail design as well as the phenotyping of the diseases and agronomical traits are given in the material and methods section of the related publication. Further metadata on the plant material and the trial design are provided in the Supplementary information of the publication.
