“…Regarding abiotic constraints, farmers in this class mentioned flood tolerance as a selection criterion for sweet potato, which differs from the current trend of several studies, including Sanoussi et al (2016) and Jogo et al (2021), who highlighted farmers' preference for droughtresistant varieties as important selection criteria. This disparity could be explained by the fact that farmers of this class probably cultivate sweet potato in flood-prone areas, exposing them to more flooding during the rainy season, as also reported by Ezin et al (2018).…”

“…In contrast, in regions where sweet potato is intercropped with other crops, farmers may choose varieties with longer maturity periods and lower yield potential like the white flesh sweet potato (Kapinga et al, 2003). In Mozambique, the adoption of OFSP varieties was influenced by agronomic traits and access to planting material (Jogo et al, 2021). In Ghana, unsweetened sweet potato varieties were preferred and OFSP varieties that are too sweet may not be successful (Baafi et al, 2016).…”

Summary Integrating farmers’ preferences into the breeding and dissemination of new genotypes is a effective approach to enhance their successful adoption by farmers. In the case of sweet potato, a staple crop in many parts of West Africa, there is a need for more research on the selection criteria used by farmers when choosing which varieties to grow. This study aims to highlight farmers’ selection criteria for sweet potato varieties in the main production areas in Benin. A total of 480 farmers from the top three sweet potato production areas were surveyed. The relative importance of various traits for sweet potato farmers was evaluated using best-worst scaling methods. Latent class analysis was applied to find groups of farmers with similar preferences. Best-Worst Scaling analysis revealed that high root yield, root size, marketability, and early maturing were the most important variety selection criteria. Latent class analysis revealed three farmers’ groups referred to as ‘Yield potential’, ‘Market value’, and ‘Plant resilience’ classes. ‘Yield potential’ farmers were more likely to be from Atlantique and Alibori departments; they significantly committed more acreage to sweet potato production. The ‘Market value’ farmers highlighted the variety of root size and commercial value as the main selection criteria and consisted of farmers with primary education levels from the Ouémé department. ‘Plant resilience’ refers to a group of Alibori farmers who prioritize environmental issues and primarily grow sweet potatoes for self-consumption. Our findings shed light on farmers’ preferences and suggested that heterogeneity in sweet potato selection criteria was highly influenced by various socio-economic factors and location.

“…The number and the characteristics of varieties were reported as key determinants in the decision of households to adopt OFSP varieties. 69 The importance of improving the availability of adapted OFSP varieties was mentioned during the period of OFSP potential recognition in East Africa. 20,21 The improved varieties generally came from farmers landraces [70][71][72][73][74] ; imported cultivars 46,51,75 ; and bred cultivars.…”

Orange‐fleshed sweetpotato production: Progress and perspectives for value chain development in West Africa

Africa and Asia bear the greatest cases of vitamin A deficiency whereas Orange-Fleshed Sweetpotato (OFSP) as a possible solution to vitamin A deficiency, brings income, food and nutritional security for smallholders involved in its production. Reports indicated low adoption of OFSP in West Africa due to poor value chains and wide adoption of White-Fleshed Sweetpotato (WFSP). Here, we reviewed OFSP interventions and programmes undertaken in West Africa, identified constraints limiting OFSP production, and updated the required actions for OFSP value chains development in West Africa. We reported 10 significant interventions and 20 released OFSP varieties within 4 countries. The main bottlenecks to OFSP value chains development are the lack of improved cultivars exhibiting high and stable yield potential, predominance of WFSP, non-exposition of whole population to OFSP varieties, limited number of improved OFSP varieties available, and inadequacy of improved OFSP varieties to smallholder preferences. The roles of donors, research institutions, local partners, and smallholder's contributions in increasing OFSP production and consumption are provided. This will fuel the development of strong OFSP value chains in West Africa.

The principal selection objective in crop breeding has for a long time been driven by agronomic gains like yield maximization and climate resilience. Nevertheless, the continued low adoption of new varieties and documented gender technology adoption gap has triggered re‐thinking of this strategy, with end‐user acceptability of released varieties a key strategy in breeding objectives. Using a mixed methods approach with a survey of 122 producers and focus group discussions with 200 male and female producers in two major sweetpotato (Ipomoea batatas (L.) Lam) producing districts in Uganda, this study set out to understand gender‐disaggregated traits that drive acceptance for improved sweetpotato varieties, as a guide to development of new varieties in the region. A generalized structural equation modelling (GSEM) approach is used to analyze how interrelated trait preferences shape acceptance for improved varieties, while in‐depth insights from a qualitative approach are used to further ground observed results. Traits such as high root yields, drought tolerance, and Vitamin A are shown to be key drivers to acceptance of improved varieties, while good taste and dry matter content dampen acceptance of improved varieties in favor of landraces. Male farmers are also shown to mainly prefer agronomic traits such as high yields and stress tolerance while women mostly prefer quality traits such as good taste, Vitamin A and high dry matter content. To achieve higher acceptability and adoption of improved varieties across the gender divide, new varieties need to not only consider agronomic gains, but also quality‐related traits such as taste and dry matter content.This article is protected by copyright.
