Lodging in flax involves the tilting or laying of stems on the soil, which critically reduces yield and complicates mechanized harvesting. A 5-point scale is used to assess variety resistance, where 5 points correspond to upright plants.

The assessment of flax resistance to lodging is carried out visually on a 5-point scale. At 5 points, plants maintain a vertical position, whereas scores of 1–2 points indicate severe lodging, making mechanical harvesting practically impossible due to the tilting or complete flattening of stems against the soil.
The primary agronomic causes of lodging are excessive nitrogen nutrition, which provokes excessive stem growth while lignin is deficient, as well as placing the crop after predecessors with high nitrogen content in the soil. Lodging degrades the quality of fiber and seeds, hinders the drying of crops, and promotes the development of diseases; therefore, selection for stem strength is a key direction in flax breeding.
