xLogarithm of odds (LOD). A LOD threshold was determined by a 1,000-permutation test at α=0.05, which is 2.51 and 2.19 for isolate 40412 and 2457, respectively.

wPhenotypic variance explained by the locus.

vAdditive effect. The positive value indicates that Socheong2 provides the resistance allele.
