Map of the 4A-1 QTL region, genotype of the individuals selected as HIF founders and phenotype of the HIFs. a Genetic map of the 4A-1 QTL region. The red section indicates the highest probability interval for the QTL. b Trace of the log probabilities (LOGP) for this region for the dark (solid line) and light (dashed line) glasshouse data. c Illustration of the heterozygous regions in the HIF founders. d Illustration of the germination phenotype (GI) of the progeny of the five HIFs. The colors represent the frequency of the different genotypes: homozygous plants with the QTL (red), homozygous without the QTL (blue) and heterozygous (green). The areas representing the different classes are equivalent and the number of individuals tested within each class is given
