This study aimed to identify cassava quality attributes preferred by users along the food chain, in order to provide breeders with criteria for prioritisation. Survey and consumer-testing studies were conducted within Apac and Luwero districts in Uganda. Additionally, sensory evaluation by trained panellists was conducted to determine descriptors for assessing quality of boiled roots. Results revealed softness of boiled roots and in-ground storability as key attributes influencing varietal preference besides high yield, non-bitter roots, disease resistance, early maturity and drought resistance. For some attributes like in-ground storability, preference differed significantly between locations and showed differentiation by gender. Local varieties were found to be superior in quality attributes. From sensory evaluation, twenty-one descriptors associated with appearance, texture, taste and aroma of boiled roots were determined. Findings from this study are vital for breeders to adopt gender-responsive approaches in order to develop varieties that meet the needs and preferences of end users.
本研究旨在确定食物链上用户偏好的木薯品质属性，以便为育种者提供优先排序标准。在乌干达的阿帕克和卢韦罗地区开展了调查和消费者测试研究。此外，由经过培训的小组成员进行了感官评价，以确定用于评估水煮块根品质的描述词。结果显示，除了高产、无苦味块根、抗病性、早熟和抗旱性外，水煮块根的柔软度和地下贮藏性也是影响品种偏好的关键属性。对于一些属性，如地下贮藏性，不同地点的偏好差异显著，且存在性别差异。发现地方品种在品质属性方面更具优势。通过感官评价，确定了21个与水煮块根的外观、质地、味道和香气相关的描述词。本研究的结果对于育种者采用性别敏感方法以培育满足最终用户需求和偏好的品种至关重要。
