Le sorgho grains sucr\u00e9s [Sorghum bicolor (L.) Moench] contribue \u00e0 la diversification des ressources alimentaires et nutritionnelles des populations du Burkina Faso. Ses grains sucr\u00e9s sont consomm\u00e9s au stade grains p\u00e2teux. Plusieurs \u00e9tudes ont permis d\u2019\u00e9valuer les connaissances paysannes et la diversit\u00e9 g\u00e9n\u00e9tique de cette ressource phytog\u00e9n\u00e9tique. Cependant, le manque d\u2019informations sur la stabilit\u00e9 g\u00e9n\u00e9tique du sorgho grains sucr\u00e9s au regard de sa culture en association avec plusieurs autres types de sorgho constitue un frein \u00e0 la gestion efficace de ses ressources g\u00e9n\u00e9tiques. La pr\u00e9sente \u00e9tude vise donc \u00e0 d\u00e9terminer la relation g\u00e9n\u00e9tique entre ce sorgho et deux autres types de sorgho cultiv\u00e9s au Burkina Faso. Ainsi, 34 accessions de sorgho constitu\u00e9es de 14 accessions de sorgho ordinaire, 10 accessions de sorgho \u00e0 tige sucr\u00e9e et 10 accessions de sorgho grains sucr\u00e9s ont \u00e9t\u00e9 caract\u00e9ris\u00e9es en 2018 \u00e0 l\u2019aide de 15 marqueurs microsatellites nucl\u00e9aires (SSRs) et de 08 marqueurs chloroplastiques (CCMP). Ces analyses mol\u00e9culaires avec les marqueurs SSRs ont r\u00e9v\u00e9l\u00e9 une importante diversit\u00e9 g\u00e9n\u00e9tique au sein des diff\u00e9rents types de sorgho. La distance minimale de Nei a montr\u00e9 de faibles valeurs comprises entre 0,02 et 0,12 entre les types de sorgho. La diff\u00e9renciation inter-types de sorgho a \u00e9t\u00e9 importante (Fst 0,25). Seul l\u2019indice de diff\u00e9renciation g\u00e9n\u00e9tique entre le sorgho grains sucr\u00e9s et le sorgho \u00e0 tige sucr\u00e9e a montr\u00e9 une diff\u00e9rence significative. La structuration a montr\u00e9 principalement deux groupes h\u00e9t\u00e9rog\u00e8nes. Des huit marqueurs CCMP, seuls deux ont r\u00e9v\u00e9l\u00e9 un polymorphisme \u00e0 150 et 200 pb. Cette \u00e9tude est primordiale pour une gestion p\u00e9renne des ressources g\u00e9n\u00e9tiques du sorgho grains sucr\u00e9s.<\/p>\n<\/section>\n
