By SVN019: Experiments at the experimental field station "Jablje" located near Ljubljana. Sowing: 4/42008, 90 plants per accession were transplanted to the field on 25/4/2008. Planting density was 30 cm x 30 cm, plants were arranged in four-row stripes.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
By SVN019: Meloidogyne hapla and M. ethiopica resistance test in pots in growth chambers, 11 hours light/25°C, 13 hours dark/20°C, air humidity 60%. Extracted egg and second stage juveniles (Pi = 3000 per plant) were used to inoculate seedlings. After 45 day after inoculation the roots of lettuce test plants were examined for the extent of nematode multiplication (Pf). Reproduction factor (Rf) = Pf/Pi. Rf < 1 = resistant/tolerant, Rf > 1 = susceptible.ECPGR CCDB Lettuce data from AUT046, DEU146, GBR006, GBR017, NLD037 and SVN019 extracted 2018-12-03.
