Abstract

Identification of molecular markers for the flower type in the ornamental crop Calluna vulgaris.

The establishment of a marker-assisted selection system for the economically important ‚bud-flowering‘ phenotype in the ornamental crop Calluna vulgaris is of great interest to practical
breeding companies, as it would allow selection at the juvenile stage.
Segregation analyses revealed a monogenic recessive inheritance of the bud flowering trait. Since in C. vulgaris only sparse molecular data are available, the search for molecular markers in a segregating backcross progeny was accomplished using PCR techniques based on random primers. Two candidate RAPD markers in coupling of the trait of interest were identified. Results on their applicability in different populations and independent varieties are presented. Their transformation capability to sequence characterized amplified region and single strand conformation polymorphism markers are described and discussed in the context of marker-assisted selection strategies in breeding of ornamental crops.
