dc.descriptionCommon bean (Phaseolus vulgaris L.) is an important legume in Tanzania, providing food, nutrition, and income. Since 2017, Tanzanian bean production has increased significantly, driven by factors such as changing dietary preferences, market and consumer demands, population growth, and urbanization. However, adoption of improved bean varieties remains low (14%) due to limited information about farmers’ trait preferences for improved varieties. This study evaluated farmers’ preferences for common bean varieties using the tricot (triadic comparison of technology) approach, in trials across three diverse agroecosystems of Tanzania. Eighteen bean genotypes were tested with 372 farmers. Each farmer evaluated three genotypes, ranking them in order of preference, providing reasons for their choice. Men’s participation (53.9%) was higher than women’s (46.1%) in common bean trial establishment, management, and Participatory Variety Selection (PVS), indicating a greater involvement of men in bean production in Tanzania. Genotypes NUA 48, NUA 64, Sweet Violet, and VTT923-23-10 were identified as the top-performing genotypes in terms of yield and farmer preference. High yield, market preference, and disease resistance were key selection criteria. Cooking suitability with banana and compatibility for intercropping emerged as important farmer preferences, reported for the first time in Tanzania, suggesting the importance of incorporating these traits in future variety development. Gender-specific trait preferences were also observed, with women prioritizing post-harvest traits, while men and youth focused on agronomic attributes and marketability, respectively. These findings underscore the importance of incorporating culturally preferred, high-performing agronomic traits into breeding programs, and ensuring equal participation in variety selection by women, men, and youth. Such inclusive approaches are crucial for enhancing improved bean variety adoption rates and boosting crop productivity. Beyond the tricot approach to varietal selection, this study provides deeper insights into gender-differentiated trait preferences and contextual factors influencing adoption, offering evidence to guide more demand-driven and inclusive bean breeding strategies.
