Experiment details

Experiment desciptionDataset remarkExperiment start yearExperiment end yearExperiment report
Multiplication in greenhouse, no artificial light. Three treatm: no treatment (sow.date:21/3), 48 day vernalisation germinated seeds (sd:9/2, temp:.5C) and foliar gibberellin sprays 20 ppm with wetter (sd:21/3,spr:9/5). Planting date:22/4.Phenotypic data CGN1988
Test potato aphid + lettuce aphid resist. Samples tested differ from CGNacces. Plants raised aphid free, planted in field 50x50cm., 4 repl. Natural aphid attack of July peak, sequential sampling of aphids per plant. Tests in several years.Phenotypic data CGN1980
Test lettuce root aphid resist. Samples tested differ from CGN acces. Seedl. unif. vigor in 5cm pots, 19oC, mercury vapor, add. light to 16h. Inoc.: 2 weeks aft. potting, 1 newly mature virginoparous aphid /pl. on roots. Scored 2 w. later.Phenotypic data CGN1980
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
Field trial. Sowing date 16/3, planting date 26,27/4/94. 23 reference varieties. Location de Goor. Planting distance 30x30. Mainly butterhead, grasse and stalk lettuce.Phenotypic data CGN1994
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
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
Screening of Bremia resistance by plant breeding company, inoculation 7 days after sowing, scoring of resistance 18 days after sowing.Phenotypic data CGN2014
