Research Interests

Plant breeding is currently facing new issues related to global warming and the need to limit environmental impacts of agriculture. Many traits of interest in plant breeding have a complex genetic architecture that is still poorly known. Development of genotyping, then sequencing approaches as well as the access to new other “omics” information make it now possible to better decipher trait architecture and to develop new breeding approaches. My main subjects of research are related to the development of methods and experimental designs for QTL (Quantitative Trait Loci) detection and marker-assisted selection, with a specific focus on multiparental and hybrid designs and applications on Maize. With the advent of high-throughput genotyping approaches, my subjects of research are now more specifically oriented towards:

  • Association mapping and its combination with Linkage Mapping. I am interested in understanding parameters influencing detection power () and in the development of methods to better decipher group specific QTL effects (1).

  • Genomic selection. Recent projects deal with the optimization of calibration sets to improve prediction accuracy (, 2, 3), the impact of group structuration on prediction efficiency (4, 5). I am also studying the potential of genomic predictions to identify interesting sources of favorable alleles in genetic resources and to better manage diversity in breeding programs (6, 7, 8, 9, 10).

  • Hybrid breeding. I contributed to develop an original multiparental design to identify loci involved in the GCA and SCA components of hybrid value for silage related traits and evaluate the possibility of replacing testcross evaluation by genomic predictions calibrated in an incomplete factorial to revisit recurrent reciprocal breeding schemes (11, 12, 13, 14). More generally I am interested in understanding the impact of heterotic group structuration on hybrid performances in order to better understand/predict heterosis.

Most of my research is done in collaboration with private breeding companies mostly on Maize but beyond Maize my objectives are to develop methods and tools applicable to other species, such as “OptiMAS”   , a decision tool for implementing marker-assisted selection. Beyond Maize, I am therefore also contributing to projects on different other species (Tomato, Cucumber, Linus, Legumes…).

Main ongoing / recent project responsibilities and community implication

  • Coordinator of the WP4 of the Amaizing Project (ANR investment for the Future, 2011- )
  • Co-coordinator of Promaïs SAMMCR projects (2010- ) related hybrid breeding.
  • Co-coordinator of the INRAE network “R2D2” on the implementation of genomic selection in plant and animal breeding
  • Member of the CTPS, Maize section (2015-2019).
  • Alternate member of the scientific council of INRAE “Plant Biology and Improvement” (present BAP) division (2012-2016)
  • Associate editor for Theoretical and Applied Genetics (2016 -) and Crop Science (2008-2010)
  • Member of the scientific committee of the Eucarpia Biometrics conference (2012-)

Teaching

  • I give lectures on QTL detection, Marker-Assisted Selection and Genomic Selection to different Masters in AgroCampus Ouest, AgroparisTech. I contribute to the Master of plant Breeding of the CIHEAM, Zaragoza, Spain on the interest of Biotechnologies in Maize breeding.
  • I also regularly contribute to courses given for scientists from public institutes or private companies organized by ASFIS, with the framework of projects (Amaizing, Selgen) or organized internally by private breeding companies on QTL detection/GWAS/MAS/GS.
