Prediction and management of Genome and Population Diversity in forest trees

Equipe Prédiction

Objectives

  • To gather knowledge about structure and polymorphism of forest tree genomes.
  • To study genetic architecture of traits under selection (natural and artificial) using quantitative genetics, linkage and association mapping. Traits studied: growth, phenology, pest resistances and wood properties.
  • To develop prediction models for the phenotype integrating explicitly genome structure, function and dynamics (linkage, dominance, epistasis …).
  • To characterise forest natural population dynamics and diversity in connection with conservation programs and strategies of improved material deployment.
  • To develop selection methods adapted to the needs of forest sector and in the frame of sustainable management of forest diversity: from low cost strategies to genomic selection.

________________________________________________________________

Species

  • If Poplar is a model species for which all the objectives are developed, some of these objectives are also developed on larch, ash tree, wild cherry, pine and Douglas fir. Low cost selection methodologies are considered for orphan species (Sorbus spp., Acer spp. ...) which do not benefit from a dedicated breeding program.

Additional keywords

  • High throughput phenotyping, Heterosis, Participatory breeding, Genotype x Environment interaction, Molecular markers.
