A technique for estimating the spreading angle of wheat roots is described and various methods of testing and sampling are discussed. The use of gravel beds with 3 or 4 replicates consisting of a single 1‐m row per variety or line and samples of 5 to 10 plants per row is recommended. High correlations were found between varietal means of spreading angles and lodging rates from a series of field trials grown under various environmental conditions. Spreading angle estimates may serve as a method of selecting for lodging resistance.
