QTL analysis of OPS phenotype with fenitrothion treatment in the F₉, F₁₀, and F₁₁ RIL populations. (a) The logarithm of odds (LOD) graphs for fenitrothion treatment using RILs in each population (left). The gray line represents an LOD threshold = 3, and the red line represents an LOD threshold based on a permutation test with 1000 iterations. Right panel represents plot phenotypes versus marker genotypes analysis corresponding to graphs. (b) Summary of QTLs identified in (a). The same QTL marker was obtained in the F₉, F₁₀, and F₁₁ RIL generations. PVE indicates phenotype variation explained. Marker intervals were estimated based on confidence intervals (1.5-LOD).
