“…Recently, Dery et al . (2021) related consumer preference to sensory attributes in Ghana and Nigeria, identifying three different consumer segments preferring different varieties based on combinations of appearance, sweetness, flavour and texture. The relationship of physicochemical properties to the consumer preference clusters remains to be reported, but may help to guide selection efforts, when available.…”

“…There appeared to be indications of preference clusters for chunk fries, with an OFSP variety preferred due to sweetness and colour by a significant proportion of the population, and less sweet, white‐fleshed varieties preferred by others, similar to the findings recently reported by Dery et al . (2021). The authors noted that differences in preference for boiled sweetpotato were masked by frying, and overall acceptance increased in fried samples.…”

“…This review was conducted to complement detailed studies involving producers, processors and consumers to develop a product profile for chunk fried sweetpotato in West Africa, where fried sweetpotato is increasingly important. The studies, conducted in Nigeria and Ghana used gender disaggregated surveys and consumer preference mapping complemented by descriptive sensory analysis to identify and characterise preferences for chunk fried sweetpotato in Ghana and Nigeria (Ssali et al ., 2021; Dery et al ., 2021). Consumer preferences are paramount to the adoption of improved varieties, and chunk fry product profile(s) will help guide ongoing sweetpotato breeding efforts in the region (Thiele et al ., 2021).…”

“…This review of the state of knowledge of fried sweetpotato in West Africa was undertaken to set the stage and underpin the design of subsequent field and laboratory research aimed at developing a product profile to guide breeding for high quality fried sweetpotato in the region (Ssali et al ., 2021; Dery et al ., 2021). In West Africa, frying of sweetpotato in the form of large wedges or ‘chunk fries’ is predominant over other forms such as chips (often referred to as crisps in England and the Commonwealth) and ‘French fries’.…”

Somatic embryogenesis (SE) and organogenesis are crucial in the development of disease free plants and genetic engineering. An investigation was conducted on the ability of treatments containing a combination of 2,4-D and Kinetin to induce either SE or organogenesis from cultured sweet potato cv Brondal leaves. Ten treatments were evaluated and each treatment had an exclusive combination of 2,4-D (at 0.05, 0.1, 0.2, 0.5 or 1 mg/L) to kinetin (at either 0.1 or 0.5 mg/L). Callus initiation occurred earlier in treatments containing higher hormonal concentrations. The 2,4-D to Kinetin ratio had a highly significant ( p = 0.001 ) effect on callus growth and proliferation. Increasing 2,4-D to Kinetin ratio promoted profuse explant callusing while increasing Kinetin to 2,4-D ratio suppressed callusing but encouraged organogenesis, in particular shoot production (treatment containing 0.05 mg/L 2,4-D and 0.5 mg/L Kinetin). Embryogenic calli were formed seven weeks after leaf culture in the treatment containing 0.5 mg/L 2,4-D and 0.1 mg/L Kinetin. The embryogenic calli that developed from this treatment emerged from previously nonembryogenic calli. Plantlets produced via the SE pathway proved to be weak and unviable and died within four weeks of germination. In contrast, plantlets produced under organogenesis were strong, grew vigorously, and could be subcultured several times. This disparity may be accounted for by the fact that the cv Brondal embryos that developed under SE were not exposed to an embryo maturation staged before plantlet germination was initiated. The maturation stage would have assisted embryos to reach physiological maturity and a desired level of desiccation, both being critical elements in embryo to plantlet conversion. In this experiment, cv Brondal regeneration from leaf explants was successfully achieved via organogenesis using 0.05 mg/L 2,4-D and 0.5 mg/L Kinetin, and tentative steps towards development of SE based regeneration protocol were established using 0.5 mg/L 2,4-D and 0.1 mg/L Kinetin.

Sweetpotato (Ipomoea batatas L.) is an important staple crop cultivated in over 100 countries, and the storage roots and vines provide food for humans and livestock. Sweetpotato consumption and demand for its value‐added products have increased significantly in the last two decades and have led to new cultivar development, expansion in acreage, and increased demand in the United States and its export markets. Despite the known nutritional components and other health benefits, further research is needed to characterize the genetic diversity and chemical composition related to their storage root qualities, essential in developing consumer‐preferred cultivars that offer host plant resistance against pests and pathogens. There is a critical need for research on non‐pesticidal control approaches that can provide safe, effective, economical, sustainable, and environmentally sound pest and disease management techniques, especially for socially disadvantaged small farmers in the United States. Moreover, climate change can significantly impact future production practices and yield and may directly or indirectly affect crop pests, weeds, and diseases. In this review, we discuss the current status, challenges, and future approaches associated with sweetpotato production practices; health‐promoting properties of sweetpotato cultivars; value‐added products; genetic diversity and germplasm; pest and disease management; weed and water management; pollination ecology; and other agronomic and cultural practices that may impact sustainable sweetpotato production by small‐scale, organic, and large‐scale growers.
