摘要: The chromosomal sites of 5S and 45S rDNA genes were revealed by fluorescence in situ hybridisation, used as landmarks to resolve the ambiguous taxonomic status tetraploid Vicia amoena var. (Fabaceae). Comparisons number location loci V. sericea, pseudorobus, dumetorum, pisiformis cracca confirmed that var or a closely related diploid, was likely progenitor tetraploid. However, contains chromosomes bearing which are probably derived from another species, such suggesting it is an allotetraploid product interspecific hybridisation event. This corroborated with genomic DNA not only showed more than one chromosome set, but also its constituent sets have undergone considerable reorganisation.
