aA, C followed by a number designates the linkage group where the QTL was detected. bLength of one LOD score confidence interval. cPeak effect of the QTL (LOD, limit of detection). dAdditive effect: positive additivity indicates that the QTL allele originated from the parental line EXPRESS; negative additivity indicates that the QTL allele originated from the parental line SWU07. ePercentage of the phenotypic variance explained by each QTL. f“-G” and “-C” represent trails performed in German and China, respectively and followed by year environment.
