Lodging in oilseed rape

Brassica napus var. napus

Lodging in oilseed rape is a significant agronomic trait, evaluated using scoring scales prior to harvest to determine crop resistance and potential yield losses.

In the reference 767 varieties crop Rapeseed, where this is mentioned in the description.

The evaluation of oilseed rape lodging is conducted visually using 5-point or 9-point scales, where higher scores correspond to resistant upright plants. The methodology involves recording the degree of stem inclination, the pattern of their arrangement, and the ability to recover after early lodging, often using challenge conditions such as high-density stands or excessive nitrogen fertilizer rates.

This trait directly affects the efficiency of mechanical harvesting, the quality of oilseeds, and the uniformity of their maturation. The risk of lodging is closely related to plant height, which makes the development of short-stemmed and medium-height varieties a key breeding objective. Additional factors for stem resistance include balanced potassium and magnesium nutrition, as well as the optimization of crop stand density.
