The shape is one of the essential components of the visual quality of ornamental plants. It is the result of their architectural construction, depending on growth and branching processes under the effect of the genetic and environmental determinism. The market currently demands compact and branched plants. To meet this demand, the plant shape can be controlled by the genetic way, with a better understanding of the heritability and the heredity of the architectural components, and by the environment (climatic and cultural). Within the framework of the project ARIAGE, in rose bush, the heritability of the main architectural components was moderate, leaving open the possibility of controlling the architecture by the environment. Two levers are thus available to control the plant shape, the variety brreding by the breeder and the environmental monitoring of the plant by the horticulturist.
