“…Its high popularity is due to the introduction of mutants with extended flowering time into commercial breeding. The so-called “bud-bloomers” (or “bud-flowering” phenotypes [2]) were probably derived from two British clones collected in 1936 and 1948 and several individuals found in natural populations in 1970 in the Netherlands [1]. Today, bud-bloomers make up the major market share of C .…”

BackgroundCalluna vulgaris is one of the most important landscaping plants produced in Germany. Its enormous economic success is due to the prolonged flower attractiveness of mutants in flower morphology, the so-called bud-bloomers. In this study, we present the first genetic linkage map of C. vulgaris in which we mapped a locus of the economically highly desired trait “flower type”.ResultsThe map was constructed in JoinMap 4.1. using 535 AFLP markers from a single mapping population. A large fraction (40%) of markers showed distorted segregation. To test the effect of segregation distortion on linkage estimation, these markers were sorted regarding their segregation ratio and added in groups to the data set. The plausibility of group formation was evaluated by comparison of the “two-way pseudo-testcross” and the “integrated” mapping approach. Furthermore, regression mapping was compared to the multipoint-likelihood algorithm. The majority of maps constructed by different combinations of these methods consisted of eight linkage groups corresponding to the chromosome number of C. vulgaris.ConclusionsAll maps confirmed the independent inheritance of the most important horticultural traits “flower type”, “flower colour”, and “leaf colour”. An AFLP marker for the most important breeding target “flower type” was identified. The presented genetic map of C. vulgaris can now serve as a basis for further molecular marker selection and map-based cloning of the candidate gene encoding the unique flower architecture of C. vulgaris bud-bloomers.

“…Munson, 1984. This is made easier if they can be grouped under some botanical category (since all are basically natural products) which will also cover wild, not yet cultivated, plants (McClintock, 1986). T o cite just one example, plants of Erica tetralix L. with untypical racemose inflorescences instead of the usual umbel, have been grouped under forma racemosa (McClintock, 1982).…”
