CREA’s Genomic Models Component Successfully Validated.

The CREA’s Genomic models component was implemented in the DataBio’s platform as C22.03. In the last year of the project DataBio, the potential of the CREA’s C22.03 (Genomic models) was successfully validated in sorghum crops to improve health-promoting compounds used to manufacture specialty foods as documented in PubMed (PMID: 31653099 and DOI: 10.3390/genes10110841) and in the below diagram.

One key breeding problem modelled was predicting the performance in the antioxidant production of new and unphenotyped sorghum genotypes. The key antioxidants traits investigated were polyphenol (FEN), flavonoids (FLA), condensed tannins (TAN), and total antioxidant concentrations (TAC). The four GS models implemented in this performed comparably across traits, with accuracy ranging from 0.49 to 0.58 which are considered high enough to sustain sorghum breeding for antioxidants production and allow important genetic gains per unit of time and cost.
