Many changes in our society (urban planning, life style, economic crisis…) impact on the ornamental plant chain. Moreover, political awareness on the risk of chemicals used in plant protection (including the recent adoption of the Labbé Law) imposes a change in people behaviour and management of these plants. The whole chain of the ornamental plant breeding and distribution has been aware for many years of the change and the need to develop new breeding programs for ornamental plants. These changes are in progress but take time; for example, the breeding of new varieties of rose is a long, challenging and labour process. In rose breeding, disease resistance is today one of the main traits but combined with other major traits of ornamental plants such as flower colour, fragrance and architecture. To help the breeders, new research projects have been developed in collaboration with private companies in order to understand the genetic determinism of disease resistances and to develop new tools for resistance characterisation.
