In an environment where the adoption of improved varieties resulting from plant breeding programs is limited, it is essential to identify end-user preferences beforehand. A participatory survey was conducted in eight localities in Korhogo and Bouaké regions (central and northern Cote d'Ivoire respectively) to identify producers' preferences and increase the adoption of improved varieties. The study involved 160 producers and consumers through focus group discussions and individual interviews.
Sweetpotato is mostly grown on small plots (<1 ha) of land (89.2%), with women (66%) as the main producers. In the Bouaké region, sweetpotatoes are grown on mounds (100%), whereas in Korhogo they are grown on ridges (86.2%). The main food products or forms of preparation from roots are fries (34.7%), boiled (34.3%), mashed (12.4%), and sweetpotato stew (9.1%). Major constraints, including low price of roots (26.3%), low productivity (16.2%), and post-harvest storage issues (14.5%), were identified as affecting sweetpotato production.
The selection of new varieties should be oriented towards high-yielding varieties with high dry matter content, deployed stems, and roots of round, oblong, or elliptical shape with good culinary characteristics (dry matter, sweet taste, dry texture, absence of fiber). Plants must be drought resistant, be tolerant to poor soil, diseases, and pests, and have a good yield. The color of skin and flesh of the sweetpotato, although constituting criteria of choice, are not essential for the acceptance or the rejection of a variety by users. © 2023 The Authors.

在植物育种计划所产生的改良品种的采用受到限制的环境下，事先确定最终用户的偏好是至关重要的。在科霍戈和布瓦凯地区（分别位于科特迪瓦中部和北部）的 8 个地方进行了一项参与式调查，以确定生产者的偏好并增加改良品种的采用。该研究通过焦点小组讨论和个人访谈涉及了 160 名生产者和消费者。
甜薯主要在小块土地（<1 公顷）上种植（89.2%），女性（66%）是主要的生产者。在布瓦凯地区，甜薯种植在土堆上（100%），而在科霍戈地区则种植在垄上（86.2%）。根部的主要食品产品或制备形式是薯条（34.7%）、煮（34.3%）、泥状（12.4%）和甜薯炖菜（9.1%）。主要的限制因素包括根部价格低（26.3%）、生产力低（16.2%）和收获后储存问题（14.5%），这些因素影响了甜薯的生产。
新品种的选择应倾向于选择高产、高干物质含量、分枝和根呈圆形、椭圆形或椭圆形、具有良好烹饪特性（干物质、甜味、干质地、无纤维）的品种。植物必须抗旱、耐瘠薄土壤、病虫害，并具有良好的产量。甜薯的皮肤和果肉颜色虽然是选择的标准，但并不是用户接受或拒绝一个品种的必要条件。 © 2023 作者。John Wiley & Sons Ltd 代表化学工业协会出版的《食品科学杂志》。
