R, MR, and S mean resistant, moderately resistant, and susceptible to disease, respectively
RL means resistant line and notation in parenthesis is pedigree number
Average lesion length was measured using 3 leaves mostly inoculated
HR: Highly resistant (< 1 cm lesion length) R: Resistant (1-5 cm), MR: Moderately resistant (5-10 cm), S: Susceptible (> 10 cm)
SD: Standard deviation
C.V.: Coefficient of variation
ns, *, and ** mean no significant, significant at p < 0.05, and p < 0.01 by t-test, respectively
Day after seedling
Brown rice yield of Unkwang was a standard
