The evolutionary potential of Baker's weediness traits in the common morning glory, <i>Ipomoea purpurea</i> (Convolvulaceae)

Abstract

We found that increased weediness in the common morning glory is more likely to occur through selection on reproductive output and competitive ability rather than through selection on growth rate. Assessing Baker's traits in a quantitative genetics framework can provide a solid perspective on their evolutionary potential and a unique framework within which to determine how weeds will respond to different environmental stresses and/or scenarios of global climate change.
