| Abstract:
A temptative forecast is proposed on possible evolution of breeding goals for new ornamentals while considering the major changes at international level. Following points have been discussed: the increase of consumption and the development of new production area, the changes of consumers' tastes, possibilities offered by genetic transformation as well as plant breeders' right. It is anticipated that diversification through the use of new genus and species will increase and for some of them new breeding programs will be launched to propose better suited varieties. Consumers' tastes will be strongly influenced in the long term by an increasing concern in quality of products and environmental protection resulting in a stronger request for disease and pest resistant plants that need not to be sprayed for instance. Selection against the most detrimental viruses will complement sanitary certification techniques to answer the demand for virus tested plant material in the European Union. Among possible techniques, genetic transformation has been chosen as a case study; a comparison has been established between information given in publications and plants proposed for field trials in several countries. Several fixed goals have been reached; results from others are still expected like virus resistance, modification of aromatic constituents, alteration of the carotenoid pathway. Plant protection through Plant breeders' right is rather favorable to the development of new varieties even if the patenting of transgenic plants might limit the access to genetic resources. | |
