In order to investigate the intraspecific variation of Prunus yedoensis
(Someiyoshino) and interspecific relationship among P. yedoensis,
P. lannesiana (Oshimazakura) and P. pendula (Edohigan), DNA fingerprinting
study was conducted by using two different kinds of probes, M13 repeat
sequence and (GACA)4 synthetic oligonucleotide. In this study, 68 plants of
P. yedoensis grown in 46 prefectures in Japan were investigated.
All the P. yedoensis individuals investigated showed the completely same
banding pattern, indicating their clonal origin from a single plant. On the
other hand, each of P. lannesiana and P. pendula individuals investigated
showed a unique banding pattern, suggesting a considerable amount of genetic
variation in these two species.
About 90% of bands in DNA fingerprints of P. yedoensis were detected in either
P. lannesiana or P. pendula. This result supports the hypothesis that
P. yedoensis is an interspecific hybrid between P. lannesiana and P. pendula.
From those results, it is concluded that P. yedoensis was produced only once
through hybridization between P. lannesiana and P. pendula, and that this particular
hybrid plant has been spread vegetatively all over Japan.
