  abstract = {{O}ngoing global climate changes imply new challenges for agriculture. {W}hether plants and crops can adapt to such rapid changes is still a widely debated question. {W}e previously showed adaptation in the form of earlier flowering in pearl millet at the scale of a whole country over three decades. {H}owever, this analysis did not deal with variability of year to year selection. {T}o understand and possibly manage plant and crop adaptation, we need more knowledge of how selection acts in situ. {I}s selection gradual, abrupt, and does it vary in space and over time? {I}n the present study, we tracked the evolution of allele frequency in two genes associated with pearl millet phenotypic variation in situ. {W}e sampled 17 populations of cultivated pearl millet over a period of 2 years. {W}e tracked changes in allele frequencies in these populations by genotyping more than seven thousand individuals. {W}e demonstrate that several allele frequencies changes are compatible with selection, by correcting allele frequency changes associated with genetic drift. {W}e found marked variation in allele frequencies from year to year, suggesting a variable selection effect in space and over time. {W}e estimated the strength of selection associated with variations in allele frequency. {O}ur results suggest that the polymorphism maintained at the genes we studied is partially explained by the spatial and temporal variability of selection. {I}n response to environmental changes, traditional pearl millet varieties could rapidly adapt thanks to this available functional variability.},
