dc.description.abstract | Crop populations in smallholder farming systems are shaped by the interaction of biological,
ecological, and social processes, occurring on different spatiotemporal scales.
Understanding these dynamics is fundamental for the conservation of crop genetic
resources. In this study, we investigated the processes involved in sorghum and pearl
millet diversity dynamics on Mount Kenya. Surveys were conducted in ten sites distributed
along two elevation transects and occupied by six ethnolinguistic groups.
Varieties of both species grown in each site were inventoried and characterized using
SSR markers. Genetic diversity was analyzed using both individual-and
population-based
approaches. Surveys of seed lot sources allowed characterizing seed-mediated
gene flow. Past sorghum diffusion dynamics were explored by comparing Mount
Kenya sorghum diversity with that of the African continent. The absence of structure
in pearl millet genetic diversity indicated common ancestry and/or important pollen-and
seed-mediated
gene flow. On the contrary, sorghum varietal and genetic diversity
showed geographic patterns, pointing to different ancestry of varieties, limited pollen-mediated
gene flow, and geographic patterns in seed-mediated
gene flow. Social and
ecological processes involved in shaping seed-mediated
gene flow are further
discussed. | en_US |
