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
Screening of Bremia resistance by plant breeding company, inoculation 5-7 days after sowing, scoring of resistance 18 days after sowing.Phenotypic data CGN2017
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
