Abstract
A rare phenomenon of the occurrence of novel non-parental chloroplast DNA (cpDNA) variants in natural sexual interspecific hybrids between Populus deltoides var deltoides and P. nigra, P. x canadensis is described. Restriction fragment variation of cpDNA in 17 P. x canadensis cultivars was examined and compared with that of representative samples of P. deltoides and P. nigra using 83 combinations of 16 restriction enzymes and six Petunia hybrida cpDNA probes. Twelve cultivars had one to five novel non-parental cpDNA fragments in the chloroplast genome region homologous to the 9.0-kb PstI cpDNA fragment of Petunia from the large single-copy region.
