| Abstract:
Dendranthema pacificum (Nakai) Kitam and other Dendranthema species were collected from the wild in Japan and also from the trade in the United States. They were evaluated in the greenhouse for growth and flowering responses and subjected to random amplified polymorphic DNA (RAPD) analysis. Genetic diversity of D. pacificum was observed by using molecular markers and also by greenhouse forcing evaluation. Both the morphology and the RAPD analysis indicated that Dendranthema pacificum accession 1-7 collected in the trade in the United States could be a hybrid between D. pacificum and other species with ray florets. Selection of D. pacificum as a new bedding plant should consider compactness of the plants, the number of runners produced, and also flowering time. | |
