Pea MUlti-STress adaptation and biological regulations for yield improvement and stability

 Pea Must

Research

Context and Issues

  • Develop novel pea varieties and optimize plant-symbiotic interactions for stabilizing seed yield and quality, in the context of pesticide reduction and climate change
  • Enhance national and international research and competitiveness of the French breeders and pea production

Objectives

  • Undertake a program of genomic selection targeted to low-input cropping systems
  • Discover molecular determinants of disease, insect and frost partial resistance in pea and faba bean
  • Investigate the potential of architecture and plant-symbiote interactions in breeding for multiple stress tolerance
  • Provide enhanced platforms for gene validation in pea
  • Devise best breeding strategies towards optimized yield and stress tolerance

Methodology

  • Federate actors gathering various complementary competencies (quantitative genetics, breeding, genomics, biochemistry, biotechnology, plant /pathogen, pests and symbiots interactions, agronomy, socio-economy)
  • Use associated phenotyping platforms (PPHD Dijon, DIAPHEN Montpellier, UE Epoisses, UE Le Rheu, UE Mons, UE Clermont-Theix, UE Lusignan, UE Toulouse, SNES) and national sequencing and genotyping platforms (GENOTOUL, GENTYANE, GENOSCOPE)

Main Results

  • Acquire original basic knowledge on the genetic control of multiple stress tolerance (QTL cloning, impact of plant architecture, phenology and symbiotic interactions on multiple-stress tolerance)
  • Develop unique tools for gene identification: high throughput sequence-based genotyping, translational genomic tools, association genetics panels, TILLING and VIGS platforms, user-friendly databases
  • Develop enhanced breeding methods and lines, optimizing yield under varying stress conditions
