In its natural state, meadow fescue is a diploid species with a chromosome set of 2n = 14. For breeding purposes, artificial autotetraploid forms with a chromosome number of 2n = 4x = 28 have been created.

crop Meadow fescue,
where this is mentioned in the description.
The species Festuca pratensis Huds. is characterized by diploidy, manifested by the presence of 14 chromosomes in somatic cells. This value is a species constant for natural populations of the plant.
Within the framework of breeding programs, research is being conducted on the development and study of tetraploid forms possessing 28 chromosomes. The use of tetraploids is aimed at correcting morphological parameters and increasing productivity; however, diploid cultivars remain dominant in commercial meadow fescue cultivation.
