Quantile plots comparing sheath blight disease ratings (0 = no disease to 9 = 90% or more infected) between the Rice Diversity Panel 1 (All-RDP1) and the O. sativa subpopulations, aromatic (ARO), aus (AUS), indica (IND), temperate japonica (TEJ) and tropical japonica (TRJ). The ratings were from the field (a, b) and microchamber disease index (DI) (c, d) studies conducted in Arkansas, USA (a, c) and Nanning, China (b, d). Dots indicate full ranges of observed data; green diamonds indicate means ± se; lower and upper sides of red quantile boxes indicate the 25th and 75th percentiles, respectively; horizontal red lines in boxes are medians, vertical lines indicate the 5th and 95th percentiles. Different lowercase letters indicate differences between subpopulation means for that trait based on Tukey-Kramer multiple mean comparison tests and α = 0.05
