Ploidy — Italian ryegrass

Lolium multiflorum Lam. ssp. italicum (A. Br.) Volkart

The ploidy of Italian ryegrass determines the classification of varieties into diploid (2n=14) and tetraploid (2n=28) forms, which differ significantly in morphology, forage quality, and agronomic characteristics.

In the reference 190 varieties crop Italian ryegrass, where this is mentioned in the description.

Diploid varieties of Italian ryegrass are characterized by smaller cell size, higher tillering capacity, and the formation of a dense sward. They demonstrate increased tolerance to trampling, better competitiveness against weeds, and adaptability to extreme conditions, including waterlogged soils.

Tetraploid varieties have larger cells, which leads to the formation of wider leaves and a higher concentration of water-soluble carbohydrates, improving the palatability of the forage for livestock. These forms exhibit an erect growth habit and require higher seeding rates due to their larger seed size, although they are sensitive to overgrazing and environmental stress.
