Ghana Sweetpotato Improvement Update Ted Carey Sweetpotato Support Platform –West Africa25-26 February 2013 Accra, Ghana The Sweetpotato Action for Security and Healthin Africa (SASHA) is a five-year initiative designed to improve the food security and livelihoods of poor families in Sub-Saharan Africa by exploiting the untapped potential of sweetpotato. It will develop the essential capacities, products, and methods to reposition sweetpotato in food economies of Sub-Saharan African countries to alleviate poverty and under-nutrition. SWEETPOTATO FOR PROFIT AND HEALTH INITIATIVE
Objectives • Sweetpotato Status • Sweetpotato Breeding and Varieties • Quality attributes Sweetpotato for Profit and Health Initiative: By 2020 456,750 households in Ghana benefit
Sweetpotato in Ghana • Status is rather poorly known • Not tracked on agricultural statistics • Tends not to be the highest priority crop • Sweetpotato R4D has a good track record • 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?
Sweetpotato Breeding Selection Sites and Target Zones in Ghana Target areas where sweetpotato Is currently important, or benchmark sites for CRP Systems research Breeding selection sites CRP benchmark sites CSIR - Savanna Agricultural Research Inst. CSIR – Crops Research Inst.
Selection sites are located where sweetpotato is important FARMERS MANCHORO,UPPER EAST REGION NUTIFAFE WOMEN’S GROUP, KPORKUVE, VOLTA REGION Baba Salifu, Komenda, Central Region
Some characteristics of selection sites in Ghana 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

Consumer Surveys • 300 consumers (100 in each region target region): 87% liked, but most didn’t eat often • Form: Boiled (43%); fried (35%); roasted (13%), raw (5%), mashed (4%) • Reason for liking: Sweetness (55%), nutrition (21%), satiation (10%), ease of cooking (7%), health benefits (3%), affordability (5%) • Reason for not liking: too sweet (20%), nausea (4%), stomach ache (4%), causes diabetes, malaria, cardiovascular diseases and bilharzia (40%)
Sufficient clean seed is essential for any effort at promotion
