Gene-flow investigation between garden and wild roses planted in close distance.

ABSTRACT: Rose is a major ornamental plant, and a lot of cultivars with attractive morphology, color and scent have been generated by classical breeding. Recent progress of genetic modification produces a novel cultivar with attractive features. In both cases, a major problem is the gene-flow from cultivated or genetically modified (GM) plants to wild species, causing reduction of natural population. To investigate whether gene-flow occurs in wild species, molecular analysis with DNA markers with higher efficient technique is useful. Here we investigated the gene-flow from cultivated roses (Rosa×hybrida) to wild rose species planted in close distance in the field. The overlapping flowering periods and visiting insects suggest that pollens were transported by insects between wild and cu
