Infection types of PI 306540 × PI 272557 derivatives lines (1) Pi23-15 (SrTm5), (2) Pi54-3 (SrTm5), (3) Pi57-32 (Sr60), (4) Pi57-39 (Sr60), (5) Pi57-57 (no resistance gene) and (6) Pi57-31 (no resistance gene) in response to Puccinia graminis f. sp. tritici races TTKST and TTKSK (Ug99). R resistance, S susceptible. Numbers below leaves present the average pustule size. Asterisks indicate the existence of significant differences between plants with either SrTm5 or Sr60 compared to plants without either gene (***P < 0.001)
