Repetitive DNA sequences have been isolated from a Sau3AI plasmid library of tetraploid Beta corolliflora (2n = 4x = 36), a wild relative of sugar beet (B. vulgaris). The library was screened by differential hybridization with genomic DNA of B. corolliflora and B. vulgaris. When used as probes for Southern hybridization of genomic DNA, six clones were determined to represent highly repetitive DNA families present only in the B. corolliflora genome. Five other sequences were highly repetitive in B. corolliflora and low or single copy in B. vulgaris. The insert size varied between 43 bp and 448 bp. Two sequences pBC1279 and pBC1944 displayed strong homology to a previously cloned satellite DNA from B. nana. With one exception, sequences are tandemly arranged as revealed by a typical ladder pattern after genomic Southern hybridization. The chromosomal distribution of five probes was determined by fluorescence in situ hybridization (FISH) of mitotic metaphases from B. corolliflora and a triploid hybrid between B. vulgaris and B. corolliflora. Three sequences were spread along all chromosome arms of B. corolliflora while one sequence was present on only six chromosomes. The chromosome-specific sequence pBC216 was found in close vicinity to the 5S rDNA located on B. corolliflora chromosome IV. This set of species-specific sequences has the potential to be used as probes for the identification of monosomic alien addition lines and for marker-assisted gene transfer from wild beet to cultivated beet.Key words: Beta vulgaris, FISH, repetitive DNA, species-specific sequences.
