Maize (Zea mays)

Maize belongs to the Poaceae family and performs C4 photosynthesis. It is the third most important grain crop world-wide after wheat and rice. Scientific evidence suggest a single domestication event of maize in southern Mexico around 9000 years ago.

In 2018 in the EU 67.4 million tonnes of maize grain was produced (4th largest production region globally, A further 229 million tonnes of ‘green’ maize (Eurostat) was harvested as an energy rich feed for livestock.

Target production increases of 10% due to enhanced photosynthesis have been estimated to increase value by up to €18 billion.

The maize collections for characterisation within CAPITALISE include:



(provider SSSA) a multi-parental population (MPP) built by the intercross of eight diverging parental lines resulting in recombinant inbred lines (RILs) harnessing high diversity and high recombination frequency; Recombinant intercrosses (RIXs), a set of heterozygous genotypes deriving from the intercross of RILs, will be produced and used within the project.



(provider IPK) a set of 10 maize lines with contrasting photosynthesis traits already well characterized for photosynthetic performance and induction kinetics and with sequencing-based markers.



(Provider CEA) 6,000 mutants, with insertions identified by Mu-Illumina sequencing from the Barkan Lab. US
