Asymmetrical local adaptation of maize landraces along an altitudinal gradient

Evolutionary Applications, 2008
AbstractCrop landraces are managed populations that evolve in response to gene flow and selection. Cross‐pollination among fields, seed sharing by farmers, and selection by management and environmental conditions play roles in shaping crop characteristics. We used common gardens to explore the local adaptation of maize (Zea mays ssp.
