Table IV.
QTLs detected for ascorbic acid (expressed relative to fresh weight or to dry matter weight) in the RIL-cherry population derived from the cross between a cherry tomato line S. lycopersicum cv cerasiforme (C) and a large fruited line (L)
The bins correspond to the chromosome fragment on the IL-pen map where the confidence interval of the QTL mapped. The parental species whose allele increased the trait is indicated (L, S. lycopersicum; C, cerasiforme). The average and sd of the families according to their genotype (CC or LL) are indicated. R2 is the variation explained by the QTL and LOD, the probability associated with the most likely location of the QTL detected by interval mapping. The presence of a QTL for dry matter weight (dmw) or fruit weight (fw) in the same trial in the bin is indicated. Mean values are shown with sd in parentheses. ns, Not significant.
