Description: Selection for straightness in natural stands of cottonwood can be effective in improving straightness of open-pollinated progeny. Straightness appears to be highly heritable, but it is subject to imprecise evaluation. This can be largely overcome by repeated application of an imprecise scoring system using a minimum of two views per tree separated by 90 degrees.

Keywords: Clone, crook, heritability
