Variety traits

Maturity group — Italian ryegrass

Lolium multiflorum Lam.

The maturity group of Italian ryegrass is determined by the timing of the heading stage and the rate of spring regrowth in comparison with standard varieties. This indicator is used to plan mowing schedules and manage the quality of forage mass.

In the reference 116 varieties crop Italian ryegrass, where this is mentioned in the description.

The classification of Italian ryegrass varieties into maturity groups is based on the biological characteristics of plant development rather than a fixed number of days until seed maturation. Varieties are categorized as very early, medium-maturing, and late-maturing depending on the rate of spring regrowth and the time of onset of the heading stage.

This trait is of decisive importance for agrotechnical planning, allowing for the distribution of harvest workload and preventing a sharp decline in the nutritional value of the stand due to simultaneous over-maturation. Early-maturing varieties provide the earliest possible green mass, whereas late-maturing varieties maintain a vegetative state longer, contributing to high productivity under intensive mowing throughout the season.
