QTL=quantitative trait loci; cM=centimorgan; Supp=supportive interval; LOD=likelihood-ratio test statistic; Position=maximum peak in cM, relative to the first locus on each chromosome; Additive effect=regression coefficient of the QTL at the specific position from the multiple regression analysis. Positive additive effects indicate that the PB 15520-1 (resistant parent) allele increased the value of the trait; SE=standard error; R2=coefficient of determination between the respective QTL and the phenotypic observations from the whole data set; Adj σ2g=adjusted genetic variance. Here, marker names were coded for ease of analyses, and their full names are in the supplementary material (see).
