Breeding for coffee and cocoa root resilience in low input farming systems based on improved rootstocks

Project description

Resilient rootstocks for low-input coffee/cocoa farming systems

Climate change seriously affects fruit tree crops. Thanks to grafting, rootstocks can confer enhanced tolerance to abiotic and biotic stresses. The EU-funded BOLERO project will develop phenotyping tools, apply them to evaluate coffee/cocoa root system architecture (RSA) traits, decode the microbiome of coffee/cocoa plants and interface with the root exudates with large-scale metabolic modelling. The project will use these resources to build predictive models of RSA traits in terms of genotypic data and microbiome composition and abundance to increase coffee/cocoa breeding. BOLERO will propose fast and low-cost breeding strategies to create rootstocks, test them in low-input coffee/cocoa farming systems and assess the agronomic performances and profitability of grafted plants in Vietnam.

Objective

Fruit tree crops (FTC), represented by more than 50 species grown on over 100 M Ha, are strongly affected by climate change (CC). Thanks to grafting, rootstocks can confer enhanced tolerance to abiotic and biotic stresses, providing a valuable solution to expand food production. BOLERO aims to i) develop phenotyping tools, ii) employ them to score root system architecture (RSA) traits of coffee/cocoa, including grafted plants, under controlled and on-field conditions, iii) decode the microbiome of coffee/cocoa plants and the interface with the root exudates with large-scale metabolic modelling, and iv) use these resources to build predictive models of RSA traits in terms of genotypic data and microbiome composition and abundance to accelerate coffee/cocoa breeding. This data compendium will be used in combination with a data hub to survey the genetic diversity in FTCs and use it to dissect the genetic basis of RSA traits and their plasticity. BOLERO will propose fast and low-cost breeding strategies to create rootstocks, which will be tested in low-input coffee/cocoa farming systems. The agronomic performances and profitability of grafted plants will be assessed in Vietnam. BOLERO will rely on the knowledge of the large scientific community in Europe, the support of national institutes in tropical countries, and the expertise of industries to lead a multidisciplinary study for rootstocks selection with Coffee as a model, Cocoa as proof of concept, and propose tools and techniques transferable easily to all FTCs. BOLERO will develop and demonstrate for the first time at a large scale the open-source seeds initiative. BOLERO will therefore contribute to the Biodiversity and Farm to Fork Strategies, through significant impacts on the way FTCs are bred and on the use of beneficial soil biota and biodiversity, leading on adaptation to CC, inputs used and soil carbon sequestration.

Fields of science (EuroSciVoc)

CORDIS classifies projects with EuroSciVoc, a multilingual taxonomy of fields of science, through a semi-automatic process based on NLP techniques. See: https://op.europa.eu/en/web/eu-vocabularies/euroscivoc.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.

Net EU contribution

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
