Cabbage lines (A) and scoring criteria (B) against blackleg disease. Three-month-old cabbage plants were inoculated to test their response to two Leptosphaeria maculans isolates 03–02 s and 00–100 s. Middle-aged leaves with yellow squares were infected. Infected leaves were scored two weeks after inoculation on a scale from 1−9 based on visual scoring criteria, where a score of “1” represents the least infected and “9” represents the most infected cabbage plants. In our previous assessment of seedling resistance, the lines BN4059 and BN4072 were susceptible while BN4098 and BN4303 were resistant (Robin et al., 2017a).
