Because of IITA's interest in cassava utilization by humans and livestock, selection for acyanogenesis will be an important objective of the cassava-breeding program. Selection for acyanogenesis will be based on finding cassava lines that lack the glucoside, glucosidase, and/or the glucoside and ...

A cause de l'interet que porte I'IITA a l'utilisation du manioc par I'homme et Ie betail, un objectif important de son programme de recherche sur la genetique du manioc visera a la selection de plants pour leur acyogenese. A cette fin, on tentera de decourvrir des Iignees de manioc depourvues de ...
