1000-seed weight of rapeseed

Brassica napus var. napus

A key parameter of rapeseed seed quality that determines seed size and plumpness. The indicator is used to accurately calculate the seeding rate, as seed weight directly affects nutrient reserves and the uniformity of emergence.

In the reference 107 varieties crop Rapeseed, where this is mentioned in the description.

For rapeseed, 1000-seed weight values depend on the biological form of the plant. In spring rapeseed, this indicator is typically 2.5–5 g, while winter rapeseed forms larger seeds weighing 4–7 g. A decline in these values below established thresholds often indicates shriveled seeds caused by environmental stressors such as drought, disease, or pest damage.

High seed weight is critical for rapeseed agronomy as it correlates with the energy reserve required for germination in the topsoil layer, which is prone to rapid drying. Furthermore, this indicator is the primary criterion for converting seeding rates from mass to seeds per area, which allows for achieving target plant density and ensuring technological precision in dosage by seeding equipment.
