A common weakness in standard participatory variety selections is that farmers are chosen without eye for their experience and the specific work they are doing and to which local social category they belong. Where this is considered usually very broad general categories are used such as age and sex., occupation, leve of education, farm size. Furthermore, when gender is brought in focus, the practice is mainly on having both men and women farmers in equal numbers evaluating the trials, disregarding their specific expertise or experience in farming. Another problem is that often farmers get chosen who feel comfortable talking and interacting within the sphere of a scientific evaluation, which emphasizes experience in reasoning and talking. This often excludes very skilled persons that however are not able or are normatively not allowed to communicate these skills and knowledge through language. But even if the respondent is good at talking it still does not include the tacit knowledge, the embodied skill and knowledge that people have. Breeders are however interested in detailed concrete hands-on information if they want to align with a demand led breeding approach such as the stage gate breeding approach that is now introduced in the CGIAR public sector breeding. Within the current reform to a stage gate breeding approach it is also crucial to get feedback from not only farmers but also processors/prepares and marketers who turn the RTB crop into an edible quality food product.

This is a short, full-colour guide intended for practitioners who are not yet familiar with tricot. It explains the rationale of tricot and gives an overview of the experimental cycle.

20+
This paper describes the application of large tricot trials in Nicaragua, Ethiopia and India. It demonstrates the potential of tricot to generate insights into variety adaptation, recommend adapted varieties, and aid smallholder farmers in responding to climate change. It is the first large-scale application of climate analysis on tricot data.

23+
24+
This paper shows that farmers provide accurate data in tricot trials. Their rankings converge with expert rankings for four traits. The variation between farmers still allows for accurate overall ranking of the varieties.

28+
This paper investigates the motivation of farmers who participate in tricot trials across three contrasting contexts: Honduras, Ethiopia and India. Farmers are motivated by a wide range of reasons, including intrinsic and extrinsic factors. They do not see it as a pastime, but also do not expect monetary compensation. They expect technical information and access to seeds as reward of their participation.

This paper provides an explanation of the tricot approach, how it compares to previous approaches, and some first applications. Note that it uses the Bradley-Terry model, which was replaced by the Plackett-Luce model in later publications.

35+
36+
This paper shows that tricot can be effectively combined with genomic selection for highly accurate selection in challenging production environments. Tested with durum wheat in Ethiopia, 3D-breeding doubled prediction accuracy compared to conventional methods, identifying genotypes with superior local adaptation across seasons to improve breeding decisions.
