  abstract = {{T}he general interest for genetic resources is based on the opportunities offered by their utilization. {G}enetic resources are a necessary starting point for plant improvement. {U}p to now, reflection on the management of genetic resources considered a three-step linear model : conservation -> evaluation -> utilisation. {I}n this system, it is expected that genetic resources are kept in a gene bank, in the best possible way, i.e. using methods maintaining over time the initial genetic state of the accessions and conferring them the longest life possible. {I}n this system, important characteristics of conservation of genetic resources are stability and availability. {W}e present a choice of methods of conservation directed to the maintenance of genetic stability of accessions. {W}e present also methods of conservation in relation with the availability of the genetic material for the various utilizations by the plant breeder. {C}omplementary methods are now proposed for the conservation of genetic resources. {T}hese methods correspond to a modified version of the linear model, with interactions between conservation, evaluation and utilization. {T}hese new methods place less emphasis on the conservation of genetically well defined accessions but promote genetic mechanisms allowing evolution of these accessions. {T}his evolutionary conservation is obtained by management of experimental populations, or by "on-farm" management of landraces, relying on knowledge and activity of farmers, and on local breeding. {F}or the wild relatives of crops, an in situ management is to be considered. {U}sing some examples, we discuss the constraints of these new modes of genetic resources conservation and utilization.
