Table III.

QTLs detected for ascorbic acid (expressed relative to fresh weight or to dry matter weight) in the BC-hab population

The bin corresponds 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; H, S. habrochaites). Data represent the dataset on which the QTL was observed (2001, 79 families; 2002, 68 families; m, normalized data from 130 families). The average and sd of the families according to their genotypes (LL or HH) are indicated. R² is the variation explained by the QTL and log of the odds (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 in the same trial in the bin is indicated. Mean values are shown with sd in parentheses. ns, Not significant.
