PlantaComp : Genetic experimental network of the French National Institute for Agricultural Research

Since several dozens of years, numerous genetic experiments of forcstry species wereinstalled through France. Genetic breeders of French national Institut for AgriculturalResearch actively participated in the implementation of this network, recently baptizedPlantaComp. The initial objectives of these tests werc to analyze the expression of geneticvariability and to study genetic parameters in order to create improved materials ofreforestation. This network aggegates tests comparing species, provenances, progenies andclones.PlantaComp is a remarkable storage of genetic diversity and thus pr€sents a srongstake in pr€servation of the biodiversity. Furthermore, the setting-up of the same genetic unitsin varied environments, and the follow-up over long periods of these trials, allow to haveaccess to precious information on the plasticity and the adaptation of this material in front of avariable environment, which mimes the impact of the announced climate change. Finally,these genetic experiments, installed in a rigorous way in contrasted environments andfollowed regularly for several years can also serve as a support for studies concerning otherthemes: following-up of invasions of insects, efficiency of the use of the water, the detectionof QTL...To make the most of the potential of this network, and so face the new stakes in theforestry sector, French National Institut for Agricultural Research showed one's willingnessto organize this network. So, PlantaComp could be valued through national or internationalprojects, included severat partners, linked with emergent issues of forestry research (climatechange but also production of biomass, biomolecule) while staying most closely withpteoccupations of the profession (selection of improved material).
