The genotypes containing the SUB1 QTL are marked in bold, and HT, T, S and HS denote highly tolerant, tolerant, susceptible and highly susceptible, respectively. The values presented are the mean ± s.e.m. (n = 5 for columns 1–4 and n = 10 for column 5) shown in parentheses, and values sharing the same letter in a column are not significantly different (P < 0.05) according to Tukey’s multiple range test.
