Résumé : Although the main targets of sorghum breeding programmes remain grain yield and quality in order to ensure human (in Africa) and animal (in other parts of the world) nutri$on needs, the yield and quality of the vegeta$ve biomass has been gaining more and more aHen$on as its interests in animal nutri$on, bioenergy and biomaterial increase. In this context, there is a cri$cal need to deepen our understanding of these traits in order to op$mize the efficiency of the development of new varie$es. A Backcross Nested associa$on mapping (BCNAM) design was developed to maximize the mapping resolu$on of the genomic regions of interest and provide the sorghum community with relevant gene$c materials for breeding in the context of the Sudano-sahelian region. The specific aim of this study was to iden$fy the genomic regions controlling stem yield and its biochemical composi$on.
