QTL nomenclature is given as in the likelihood profiles. PVE denotes the percentage of total phenotypic variance explained by the QTL. The additive effect (2a) is the phenotypic difference conferred by homozygous replacement of a W138 allele for a wild species allele. The sum of QTL additive effects is denoted as ∑. Standard errors are given for the estimate of 2a. The P-values give the probability of a locus contributing to the multiple regression model fit, according to an F distribution. The difference between parental lines accounted for by a QTL is given as ΔP, in units of measurement.
