Підвищення конкурентоспроможності органічної селекції рослин: сорти, адаптовані до змішаних посівів

Expected Outcome

Project results are expected to contribute to all of the following expected outcomes:

• the efficiency and competitiveness of the organic crop breeding sector are boosted by providing organic breeders with a comprehensive toolbox to develop varieties specifically adapted to intercropping and suitable for organic production;
• an improved understanding of key target traits for developing varieties adapted to intercropping farming systems is available to researchers and breeders, benefiting all agricultural systems;
• the foundation for the development of future crop varieties that enhance benefits derived by intercropping, such as improved pest/weed management, increased nutrient and water use efficiency, improved pollination, improved soil fertility, reduced soil erosion and nutrient leaching, and enhanced productivity, is established.

Scope

Plant breeding has focused on maximising yield in single species stands for monocropping systems, leading to highly productive yet specialised varieties. As a result, most varieties on the market may not perform well in intercropping systems, where productivity and benefits often depend on the interactions between crops. To support farming practices that promote agrobiodiversity, there is a need to develop varieties specifically adapted to intercropping. However, selecting varieties specifically for intercropping remains a practical challenge for breeding.

Proposals should:

• provide novel insights into interactions and mechanisms that influence intercrop performance by advancing understanding of plant traits affecting both inter- and intraspecific interactions and their impact on crop outcomes. The approach should consider eco-physiological processes and ideally encompass both aboveground crop interactions and belowground dynamics between intercropped roots and soil organisms;
• develop new organic breeding approaches that prioritise enhancing crop performance within multi-species systems, emphasising the importance of competition, complementarity and facilitation mechanisms between crops;
• identify crop combinations and superior–performing variety combinations that consistently yield well together;
• provide inputs for the development of future testing and selection criteria, as well as tools and methods for evaluating the performance of specialized genotypes in intercropping conditions, laying the groundwork for breeders and bodies entrusted to establish these frameworks.

Particular attention should be given to aspects related to the regulations for the use and development of Organic Heterogeneous Material (OHM) and/or Organic Varieties Suitable for Organic Production (OVSOP) as innovative categories of plant reproductive material.

If applicable, proposal may advance pre-existing breeding material towards the development of OHM and/or OVSOP for intercropping, making use of the knowledge and tools developed within the project.

Proposals should build on the results of relevant projects funded under Horizon 2020 and Horizon Europe and ensure collaboration with relevant ongoing projects.

Proposals are encouraged to consider, where relevant, the data, expertise and services offered by European research infrastructure in the environment, biological and food domains.

Proposals may provide financial support to third parties (FSTP) to, for instance, develop, test and demonstrate the new organic breeding approaches for intercropping.

The projects under this topic are relevant to the EU policies related to the EU Vision for Agriculture and Food, to the EU Action Plan for the Development of Organic Production , to the EU biodiversity strategy for 2030 (notably target 8) and to the Kunming-Montreal Global Biodiversity Framework (target 10).
