“Developing precision breeding-by-demand toolboxes: The grass pea case study”

Dr M. Carlota Vaz Patto

Genetics and Genomics of Plant Complex Traits Laboratory (PlantX Lab)

Consumers worldwide are increasingly concerned with food quality, environmental sustainability and, after COVID19 pandemic disruption of long food supply chains, with food security. Protein-rich and environmentally friendly legumes, locally produced, like grass pea (Lathyrus sativus L.), are an excellent answer to these concerns. Although Portugal holds promising food legumes genetic resources, a reduction in local production and consumption in the country, as well as in Europe most traditional markets occurs.

Reduced investment in breeding, particularly in nutritional/organoleptic quality, resulted in overall unattractiveness of current varieties not only to farmers/processors but also to consumers and to this national resource underuse.

To increase food legumes consumption and cultivation, breeding objectives and market preferences should be better aligned.

With the development of high-throughput genetic and phenotypic technologies, it is now possible to address breeding in a more integrated way. At the PlantX Lab, we collect and integrate multiple layers of biological information (metabolomics, phenomics, genomics) through statistical genomics, assuring an improved understanding of this complex biological system, and higher prediction accuracy for target phenotypes, such as yield and quality (through genotype-to-phenotype prediction models). During this presentation, I will revise the work developed on grass pea agronomic, biotic and abiotic stress resistance genetic basis and introduce the more recent nutritional and organoleptic quality studies on the same species.

The developed molecular toolbox based on these prediction models will be important for food legumes genotyping, product screening (e.g. quality assessment of legume batches), and marker-assisted selection for routine implementation of quality breeding objectives within the more often focused agronomic improvement.
