Only pairwise recombination estimates for visible markers were used to make this particular map. Most of the recombination data were supplied by Maarten Koornneef and David Meinke. Molecular data involving RFLP markers and recombinant inbred lines were excluded from this map because their inclusion resulted in maps that were inconsistent with available data for visible markers. This map should be viewed as simply an estimate of gene locations based on available genetic data. In most cases, the orientation of closely-linked genes has not been clearly established.
Higher values indicate more contradictions and therefore greater uncertainty in map location.
