Abstract: This dataset comprises records collected during the seed regeneration routine of the barley collection hosted at the Leibniz Institute of Plant Genetics and Crop Plant Research (IPK) between the years 1946 and 2015. The following traits were recorded: (i) Flowering Time (FT) which corresponds to days after the 1st of January of each year for winter barley, and days after the sowing date for spring barley, (ii) Plant Height (PH) evaluated in cm, and (iii) Thousand Grain Weight (TGW) expressed in g. The dataset also compromises information respecting to accession identifiers, accession numbers, sowing date, harvest year and country as the geographic place reported by donors or collectors. The dataset and metadata are formatted using the ISA-Tab format (see subfolder /ISA-Tab). The files consist of original historical data, data derived from an outlier exclusion approach, and the computed best linear unbiased estimators (BLUEs) of accessions (see subfolder /BLUEs). The data analyses were performed using linear mixed models combined with an outlier detection approach based on rescaled median absolute deviation and Bonferroni-Holm test. The statistical approaches for processing the data were performed in R and the corresponding scripts are also included (see subfolder /R_Scripts).
