To evaluate the lodging resistance of hulless oats, a five-point scale is used, where low scores correspond to high resistance. For a more objective characterization, methods of analyzing stem morphological parameters are employed, including the Atkins-Korostelev method, which determines the weight per unit length of the straw, and the calculation of indices for the length-to-diameter ratio of the lower internodes.
In hulless oat breeding, a negative correlation has been identified between plant height and lodging resistance. Striking a balance between productivity and stem strength remains an important task, as tall-growing varieties have a higher propensity for lodging, which necessitates the consideration of morphometric indices when evaluating varietal traits.
