  abstract = {{R}ice ({O}ryza spp.) is an important food and cash crop in the {R}epublic of {B}enin. {H}owever, despite its production increase in recent years, the yield of cultivated varieties remains low, and the introduction of improved varieties threatens the rice diversity existing in traditional agriculture. {T}herefore, documenting the on-farm management of rice diversity, farmers' varietal preferences, and their perceptions of the performance of cultivated varieties and species are important prerequisites for the development of on-site breeding and conservation programs. {T}o fill these gaps in {B}enin, 418 rice farmers, belonging to 21 ethnic groups, were surveyed in 39 villages using participatory rural appraisal tools. {S}ubject to synonymy, 30 improved varieties and 68 local varieties were registered and their folk nomenclature and taxonomy were documented. {T}he north of {B}enin had the highest diversity of rice with the greatest number of traditional varieties, making this region the best place for an in situ conservation program. {T}he number of rice varieties maintained per village varied from 1 to 15 (six on average). {T}he foursquare analysis revealed that the improved variety {IR} 841 was by far the most popular variety. {M}ost of {NERICA} varieties were abandoned in the south, while the north still hosts a wide range of local varieties. {T}wenty-one reasons explained varietal abandonment by farmers, varying according to geographic areas and ethnic groups. {T}he seed system was both formal and informal in the study area. {T}he participatory evaluation revealed the necessity to create and introduce tolerant/resistant rice varieties to drought and flooding stresses in {B}eninese agriculture that meet farmers' preferences. {O}ur results showed that north {B}enin would be the most suitable place for in situ conservation of local rice diversity.},
