By NLD037: Experiments at the experimental field station "Nergena" in Wageningen. Sowing: 14/3/2008 and 30 plants per accession were transferred to the field on 23/4/2008. Two 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/ .2008
Multiplication, glass house. Temperature 15-18oC, no artificial light. - no treatment:sowing date 28/3, planting date 26/4, with vernalization germinated seed:sow.d.14/2, plant.d.26/4, with foliar gibber.sprays 20ppm: sow.d.28/3, pl.d. 26/4Phenotypic data CGN1989
Tests with 14 NL and 6 Czechoslovakian races. 20 Seedling or 5 leaf discs on moistened filter paper. Inoc.5E4 sp/ml. Temp 15oC. Scored after 8-12d. Accessions heterogeneous to NL1 or NL3: only resistant plants were scored for other races. RPhenotypic data CGN1989
