Description

During the NitroSorg project, high-throughput characterization tools will be developped for protein content and digestibility, but also starch and tannin content and endosperm texture that can affect this digestibility (WP2). These tools will be used to evaluate of the current variety offer, a panel representing global diversity, and the lines currently used in selection to develop selection strategies at Eurosorgho, RAGT2n and CIRAD (WP1). Finally, on a small panel of varieties, an analysis of kafirin (sorghum storage protien) composition, an exhaustive analysis of in vitro protein digestibility and in vivo as part of poultry feeding will be performed (WP3). These analyses should allow us to assess the relevance of the high-throughput screening tools used and will lead to the definition of the target ideotypes for poultry feeding. In the long term, these results will contribute to the selection of sorghum varieties with an increased content and digestibility of proteins of their grain, and indeed an improved nutritional value.
