  • The closest marker to each QTL is shown and its location is indicated by the linkage group number followed with its map position. Only QTLs with LOD score > 2.4 are reported. The QTLs with the largest effects have been designated as EDI, FLF, FLG, and FLH and are indicated between parentheses. For each trait and environment, the relative contribution of each QTL was estimated by analysis of variance components. Because of the epistatic interaction between FLF and FLG (see text) the relative contribution of their interaction was included in the model and it is shown (FLF × FLG). The additive allele effects of FLF and FLG have been added together. The additive allele effects are estimated as the mean differences between the two RIL genotypic groups carrying the Cvi and Ler alleles (a positive value implies Cvi allele increasing the corresponding phenotypic value; a negative value, Cvi allele decreasing). Allele effects are shown in the original scale of measurement (days for flowering time and number of leafs for leaf numbers). For each trait, the QTLs interacting with the environments are indicated by * (P < 0.005). NS, not significant.
