Abstract
Repeated DNAs have been isolated from Petunia hybrida and their distribution and organisation in different Petunia species
studied. Several sequences examined can be used as probes to distinguish species with 14 chromosomes from P. parviflora, which has 18. In addition, three sequences can distinguish white-flowered species (P. axillaris, P. parodii) from pink-flowered
species (P. violacea, P. inflata). One sequence which is detected only in species with 14 chromosomes was found to be
present in tandemly-arranged, AT-rich 168 base-pair repeats. The use of these sequences in phylogenetic studies and somatic
cell genetics is discussed.
