Biological resources

MAZE DH library

In total, 1,015 doubled-haploid lines derived from three European flint maize landraces were generated: 516 from Kemater Landmais Gelb (KE), 432 from Petkuser Ferdinand Rot (PE), and 67 from Lalin (LL). The landraces were pre-selected for phenotypic variation in cold-related traits assessed in field trials and population genetic analyses.

MAZE MAGIC populations

One multi-parental dent MAGIC DH library segregating for drought and heat tolerance was established which comprises 500 DH lines derived from eight non-BSSS inbred lines.

Synbreed DH library

In total, 351 DH lines derived from six European maize landraces were generated: 19 from Campan Galade (CG), 50 from Gelber Badischer (GB), 54 from Strenzfelder (SF), 34 from Rheintaler (RT), 101 from Satu Mare (SM), and 93 from Walliser (WA). For a detailed description, see Brauner et al. (2019):

Multi-parental maize populations from the PLANT-KBBE CornFed project

Two panels of DH populations were established in the Plant-KBBE project CornFed: 11 DH populations for European Dent and 13 DH populations for European Flint maize. Each of the two panels consists of a central line (or common parent) that was crossed to founder lines that represent important and diverse breeding lines of the European maize germplasm. For a detailed description of this biological resource see Bauer et al. (2013).
