Other claims from this paper (4)
- Observation All plants of the susceptible cultivar Elisa showed highly susceptible reactions to both Berkeleyomyces pathogens after inoculation.
- Observation All La Brillante plants were resistant to both pathogens even under harsh inoculation conditions, indicating high penetrance of the trait.
- Observation The F2 population inoculated with B. rouxiae fit a 3:1 resistant/susceptible segregation ratio, indicating monogenic dominant resistance.
- Observation Nationwide surveys in Brazil indicated similar incidence and overlapping geographical distribution of B. basicola and B. rouxiae across major lettuce-producing areas.
