By NLD037: Experiments at the experimental field station "Nergena" in Wageningen. Sowing: 19/3/2007 and 45 plants per accession were transferred to the field on 25/4/2007. 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/ .2007
Screening (2000-2002) by 7 comp. associated with Plantum NL, stand. NAKT method, 30 pl. per race per acc., scoring % resist. plants, in general seperate scores by two diff. comp. per race, using the means when scores not too conflicting.Phenotypic data CGN2000
Screening with standard NAKT method, 30 pl. per race per accession, scoring percentage resistant plants.Phenotypic data CGN2003
Field trial. Sowing date 19/3, planting date 25/4, plant distance 30 x 30, 45 plants per object. Location Nergena. 23 Reference varieties.Phenotypic data CGN2007
