Fig 8

External (A, B, C) and internal (D, E, F) phoma stem canker symptoms on DH line A30 (A, D), cultivars Bilbao (B, E) and Adriana (C, F). A30 with no known Rlm resistance genes and no quantitative resistance (QR), Bilbao (Rlm4) with resistance gene Rlm4, Adriana (Rlm4 + QR) with Rlm4 and QR. Leaf petioles were inoculated with conidia of Leptosphaeria maculans isolate v23.11.9, which is virulent against Rlm4. Inoculated plants were kept at 20°C with 12h light/12h darkness and sampled at 49 days after inoculation.
