Lodging in Festulolium critically affects seed productivity, causing pollination disruption, delayed maturation, and reduced caryopsis quality. The degree of resistance is assessed visually in points or as a percentage of the crop area.

where this is mentioned in the description.
To assess the degree of lodging in Festulolium, 5-point or 9-point scales are used, where higher values correspond to an upright stem position. Crop damage is also measured as a percentage of the plot area; the critical lodging threshold that reduces seed quality is considered to be between 15–20% and 45% or higher.
The primary causes of lodging are excessive nitrogen fertilization exceeding 75–90 kg/ha a.i. and heavy rainfall during the maturation period. Lodged plants exhibit a 2–4 day delay in maturation and the formation of shriveled caryopses, which, combined with difficulties during mechanical harvesting, leads to significant seed yield losses.
