Screening for resistance against Pemphigus bursarius (Lettuce root aphid 1999;2003), Erysiphe cichoracearum (Powdery mildew 1999;2003-2004), Sclerotinia sclerotiorum (Pink rot 1999-2001;2003-2004) and Bremia lactucae (Downy mildew 2001).Phenotypic data CGN1999
Old filed observations.Phenotypic data CGN1987
Lettuce multiplication. Glashouse without artificial light. Two treatments: - no special treatment, sowing date : 8/3, planting date : 6/4, - with foliar gibberellin sprays 10 ppm, sow.date: 8/3, plant date 6/4.Phenotypic data CGN1982
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
Multiplication. 8 or 16 plants per object. Vernalisation date 24/2/97, sowing date 7/4/97, planting date 28/4/97.Phenotypic data CGN1997
Multiplication and characterisation, sowing date with vernalisation 23/2, for greenhouse 8/4, planting date 8/5.Phenotypic data CGN1998
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 by 6 companies associated with Plantum NL, about 20 pl. per acc., inoculating the 3th-4th true leaf with aphids in different stages, scoring after 10-15 days the production and colonisation.Phenotypic data CGN2008
Screening by 7 companies associated with Plantum NL, standard NAKT method, 30 pl. per race per acc., scoring % resistant plants, in general seperate scores by two diff. companies per race, using the means when scores not too conflicting.Phenotypic data CGN2014
