Breeding Legume populations for low-inputs systems

MEJORA GENÉTICA DE POBLACIONES PARA UNA AGRICULTURA DE BAJOS‐INSUMOS

Departament of plant breeding

Legumes, in general, have not benefited from heterosis. In most legumes, the absence of enough natural cross-fertilization is a major bottleneck. If insect-aided outcrossing is understood better, legumes would be major beneficiaries. Our aim is to develop specific breeding approaches integrated with bee-pollinator management to 1) obtain cultivars characterized by heterosis-mediated high productivity, resilience and pollinator-friendliness; and 2) to progress in application-oriented basic questions for a better exploitation of heterosis in legumes. To achieve this, our work design and develop hybrid technology based on the understanding of the plant-pollinator inter-play for the management of bee pollen vectors for insect-aided cross-pollination using tools from pollination ecology, plant breeding and bioinformatics. It is focused on Vicia faba as a model plant because it is a partially allogamous species pollinated by managed and solitary bees and showing significant heterosis in yield stability and resilience.
