High Resistance. Plant varieties that highly restrict the growth and development of the specified pest or pathogen under normal pest or pathogen pressure when compared to susceptible varieties. These plant varieties may, however, exhibit some symptoms or damage under heavy pest or pathogen pressure.
Intermediate Resistance. Plant varieties that restrict the growth and development of the specified pest or pathogen, but may exhibit a greater range of symptoms or damage compared to high resistant varieties. Intermediately resistant plant varieties will still show less severe symptoms or damage than susceptible plant varieties when grown under similar environmental conditions and/or pest or pathogen pressure.
Physiological races Bl:1-15 of Bremia lactucae (downy mildew) in lettuce are agronomical no longer relevant in Europe, as to the best of our knowledge these races are no longer observed in practice in Europe nowadays. Therefore reference to the races Bl:1-15 is no longer made in resistance claims with regard to B. lactucae. From May 1st 2014 onwards, the resistance claim of a variety refers only to Bl:16-31.
P.s.: Although race Bl:19 is to the best of our knowledge also no longer observed in practice nowadays, reference to the race Bl:19 will continue to be made in resistance claims with regard to B. lactucae to simplify the notation of the resistance claim. In practice this means that for example Bl:16-31 should be understood as Bl:16-18,20-31.
