Title – Ornamental character of scented geraniums by genetic transformation

Claim 1A method of genetically modifying a plant of the genus Pelargonium to modify at least one ornamental characteristic of said plant, the method comprising the steps of, transforming a live Pelargonium plant or live tissue thereof with the T-DNA of the Ri plasmid of Agrobacterium rhizogenes, and propagating the resulting transformant to obtain a plant for ornamental use.
Claim 5A method of genetically modifying a Pelargonium species or variety having a unique scent comprising transforming live plants or live tissues of said species or variety with the T-DNA of the Ri plasmid of Agrobacterium rhizogenes, and propagating the resultant transformants to obtain plants characterized by improved ornamental characteristics.

Method for the transformation of a live Pelargonium plant or live tissue with T-DNA of A. rhizogenes. The transformation is aimed at modifying an ornamental characteristic or the scent of a geranium plant.
