Abstract EN
For the purpose to improve the productivity of its reforestations and to palliate the deficit recorded in its woody sector.
Morocco as other Mediterranean countries bad proceeded hv means of the forest research since a quarantine of years to the introduction and the acclimatization of species able to resist to the irregular and hard climate of the countrv and provide satisfactory- outputs .
The first experiences realized in a twenty arboreta have shown that a certain number of pine and eucalyptus species, could be adapted to Morocco and could give good outputs despite the diversity of climatic and edaphie conditions.
On the basis of these results and in the aim to use both of the interspecific and infraspecifie variability, the National Forest Research Center has installed several provenance tests of the main species so as to identify for each zone of reforestation the best source of seed in terms of adaptation levels and production The research in genetic and forest tree improvement is increasingly considered as essential to the maintenance and to the increase of the competitiveness of the forest sector in many countries.
The general context justifying the installation of improvement program exceeds nevertheless largely the economic framework.
The sustainable development and the conservation of the genetic diversity are two principles to which subscribed Morocco and that heckle particularlv geneticist improvers.
Thus, important program research have been defined to reply to these goals.
The present study is a synthesis statement of the different realized works concerning genetic improvement of forest trees in Morocco since the creation of die Forest Research Station in 1949.

des essences susceptibles de resister au eliniat dur el irrcgulier du pays tout en t'oumissaut des rendements satisfaisants.
I .es premieres experiences realisces dans line \Iingtaine d'arboreta out montre quTm certain nombre d'especes de pins el d' eucalyptus s'adaplent ties bien an Maroc et qu'elles peuvent donner de buns rendements malgre la diversite des conditions climatiques et edaphiques.
Sur la base de ces resultats le Centre National dc la Recherche Forestiere a installe un resean de plantations comparatives d'especes et de pro\'enances at'in d'exploiter a la ibis la variabilite inter et intraspecifique et de deceler pour chaqne zone de rehoisement la on les provenances les medicares aux niveaux adaptation et production (elasseincnt des provenances selon leur adaptability et kill" productivite).
La recherche en genetique et amelioration des arbres forestiers esl de plus en plus consideree comme esscntielle au maintien et a raccroissement de la coiupetitivite du secteur forestier dans de nombreux pays.
Le eontexte general justiliant la mise en place de programme d'amelioralion depasse toutefois largemeiit le cadre eeonoinique.
Le developpemeni durable et la conservation de la diversite genetique sont deux prineipes auxqiiels souscril le Maroc et qui inlerpellent particiilierement les geneticiens ameliorateurs.
Ainsi, de vastes programmes de recherche out etc mis sur pied pour repondre a ces objectil's.
La presente etude constitue un bilan synthetiquc des differents travaux realises en matiere d'amelioration genetique des arbres forestiers au Maroc depuis la creation de hi Station de Recherche Forestiere en 1949.
