White fonio（Digitaria exilis[Kippist] Stapf）是一种未充分研究的小米作物，原产于西非，主要通过传统做法在该地区种植。该物种具有气候适应能力，生长迅速，营养丰富，并为农村社区提供生计和粮食安全。通过与几内亚Fouta Djallon地区的小农户合作，本研究调查了fonio地方品种的多样性和选择如何在生活记忆中发生变化。这项研究提供了深入了解气候和社会文化变化如何影响fonio品种和其他土著作物的种植，以及为什么他们应该被保护和进一步参与农村发展计划。exilis）是伊萨种主要作物，为西非成千上万的人提供食物。几内亚的富塔贾隆高地地区是其种植的热点，具有已知的高遗传多样性。我们的研究利用民族植物学访谈和植物标本和种子收集的数据，与来自该地区15个社区的农民合作，旨在调查地方品种的多样性和fonio在当前农业系统中的流行程度，目前，在过去的50年里，共有24个已命名的fonio品种被记录和描述，沿着其他常见的种植粮食作物。这包括两个已经消失的品种，现在已经不再种植。我们还描述了种植，谷物加工和食品制备的方法。由于生活记忆中的社会和环境变化的后果，种植福尼奥地方品种和其他作物的优先级和受欢迎程度已经发生了变化。fonio地方品种的多样性是为了适应历史气候变化而保持的，人们越来越倾向于生长期更长、产量更高的品种，而不是早季品种。
Societal Impact StatementWhite fonio (Digitaria exilis[Kippist] Stapf) is an understudied millet crop, indigenous to West Africa and cultivated in the region largely through traditional practices. This species is climate‐resilient, fast‐growing, nutritionally rich, and provides livelihoods and food security to rural communities. Through collaboration with smallholder farmers in the Fouta Djallon region, Guinea, this study investigates how the diversity and selection of fonio landraces has changed in living memory. This research provides insight into how climatic and socio‐cultural changes affect the cultivation of fonio varieties and other indigenous crops, and why they should be conserved and further involved in rural development programmes.SummaryThe millet crop white fonio (D. exilis) isa staple crop feeding thousands of people across West Africa. The Fouta Djallon highlands region of Guinea is a hotspot for its cultivation, with known high genetic diversity.Our study utilises data from ethnobotanic interviews and plant specimen and seed collections, working with farmers from 15 communities in this region with the aim to investigate the diversity of landraces and popularity of fonio within the current agricultural systems, in the present, and changes over the past 50 years.A total of 24 named varieties of fonio were recorded and described, along with other commonly cultivated food crops. This includes two lost varieties now no longer cultivated. We also describe the methods for cultivation, grain processing and food preparation.The priority and popularity of cultivated fonio landraces, and other crops, has changed, due to the consequences of social and environmental change in living memory. The diversity of fonio landraces are maintained as an adaptation to historical climatic changes, and there is an increasing preference towards varieties with a longer growing period and more reliable high yield to the detriment of early season varieties.
