A dataset containing data from a greenhouse experiment with maize in the Phenoarch platform (INRAE, France, Cabrera-Bosquet et al. 2016). It consists of one experiment with 1,671 plants grown in a greenhouse under two water scenarios, well-watered (WW) and water deficit (WD). There are two populations of genotypes, panel 1 and panel 2. Panel 1 contains 60 genotypes with 14 replicates: 7 in WW and 7 in WD. Panel 2 contains 30 genotypes with 8 replicates, 4 in WW and 4 in WD. The studied trait is the leaf area extracted from the pictures over time (LeafArea). Plants were pictured every day for 33 days. This dataset was kindly provided by Llorenç Cabrera-Bosquet and Claude Welcker.
