MAZE DH library field experiments
1015 doubled-haploid (DH) lines derived from three European maize landraces (516 KE, 67 LL, 432 PE) were phenotyped for line perse and testcross performance in up to eleven and seven environments, respectively. In total, 25 morphological, agronomic and early-development-related traits were measured. For a detailed description of the data, see Hölker et al. (2019):

Data of line per se evaluations for 9 traits in up to 11 environments for 899 double-haploid lines (471 KE, 402 PE, 26 LL), as used for the GWAS analyses in Mayer et al. 2020 are available via https://doi.org/10.6084/m9.figshare.12137142. The dataset is described in detail in Mayer et al. 2020.

MAZE DH library platform experiments
Early root growth for 939 doubled-haploid DH lines derived from three European maize landraces (490 KE, 23 LL, 426 PE) was measured under different temperature regimes using the genotyping platform GrowScreen-PaGe (Gioia et al. 2016).

CornFed DH populations
The testcross performance of 1652 doubled-haploid (DH) lines from the CornFed project that were genotyped with the Illumina MaizeSNP50 array and phenotyped for five agronomic traits in four to six European environments was evaluated. Five phenotypic traits were recorded in both panels, namely biomass dry matter yield (DMY, dt/ha), biomass dry matter content (DMC, %), plant height (PH, cm), days to tasseling (DtTAS, days), and days to silking (DtSILK, days). Data analysis and genomic prediction in multiparental populations was described by Lehermeier et al. (2014). The phenotypic data are available here:
