The 1000-seed weight is a key indicator of rapeseed seed quality and a primary parameter for calculating the precise seeding rate when planning target plant density.

where this is mentioned in the description.
Rapeseed typically exhibits a 1000-seed weight range from 2.5 to 5.0 g for spring forms and from 4.0 to 7.0 g for winter varieties and hybrids. This indicator serves as an index of seed plumpness, size, and nutrient reserves, which directly affects germination energy and the success of initial seedling development.
Accurate accounting of this parameter is necessary to prevent thinning or excessive crop density, as the seeding rate is calculated based on the target number of plants per hectare and the specific seed weight. A positive correlation is often observed between the 1000-seed weight and crop yield, although the value of the trait strongly depends on the nutritional conditions and moisture availability of plants during the seed-filling period.
