White mustard is a stably diploid species with a chromosome set of 2n = 2x = 24. In breeding research, tetraploid forms (4n) are artificially created to study their impact on productivity and to improve economically valuable traits.

crop White mustard,
where this is mentioned in the description.
White mustard belongs to diploid organisms, characterized by a constant chromosome set of 2n = 24. This value is the species standard and determines the genetic stability of the crop under production conditions.
In scientific practice, methods of experimental polyploidy are used to create forms with an altered chromosome set, such as tetraploids. These studies are aimed at increasing seed yield, oil content, and resistance to stress factors, although the results obtained are evaluated based on agronomic indicators rather than ploidy level.
