The basic idea of evaluating the root crown of field crops is to estimate the growth, development, and architecture of principal roots near the base of the shoot. Root crowns may be evaluated directly in the field, or rinsed and stored for more detailed analysis in the lab. In our experience a number of important root traits may be rapidly assessed from roots excavated and phenotyped.
