Abstract: A001-I , a species-specific repetitive sequences isolated from Alstroemeria aurea , was used in fluorescence in situ hybridization to detect the fate of A. aurea chromosomes in a series of its hybrids in this study. We could clearly detect the change of the number of A. aurea chromosomes in its related hybrids except for Chromosome 1 , the longest chromosome of A. aurea . This could be helpful to select materials in further Alstroemeria breeding.

Key words: Alstroemeria aurea, Species-specific sequence, Fluorescence in situ hybridization
