    • 13 varieties (2 OFSP, Apomuden and Bohye) released

    • Various institutions, programs and projects: CSIR (CRI, SARI, SRI), MOFA, KNUST, BNARI, UCC, UDS, UG-Legon, TU, FARA, RTIMP, WAAPP, WACCI, SASHA, RAC, Systems Research Efforts (CRP1.1, 1.2)

Sweetpotato Breeding in Ghana

  • Population improvement linked to participatory varietal development

  • Sweetness is thought to constrain demand for sweetpotato in W. Africa, so we are breeding for low sugar sweetpotato

  • Is this what we’relooking for?

Constraints: Drought can be a constraint in any AEZ, but tends to be worse in savanna AEZs, SPVD tends to be worst in forest zone, soil fertility tends to be low in most places.

Detailed assessments are underway with partners to identify value chain and seed system interventions
