By NLD037: Experiments at the experimental field station "Nergena" in Wageningen. Sowing: 15/3/2010 and 30 plants per accession were transferred to the field on 27/4/2010. Three rows with 30 cm inter-plant distance.ECPGR CCDB Lettuce data from AUT046, DEU146, GBR006, GBR017, NLD037 and SVN019 extracted 2018-12-03. This data and also some more evaluation and utilization data (not in EURISCO) are available from https://ecpgr.cgn.wur.nl/LVintro/ildb/ .2010
Field trail for the characterization of 189 accessions. Sowing date: 15-3-2010, planting date: 27-4-2010, planting distance 30 cm, 30 plants per accession, Location: Nergena, Wageningen.Phenotypic data CGN2010
Lettuce variety descriptions made available by the Netherlands Inspection Service for Horticulture up and until 2013. Descriptions are included for varieties that matched the CGN accession name.Phenotypic data CGN2013
