where this is mentioned in the description.
The origin of a hybrid ryegrass cultivar is recorded as a qualitative characteristic in variety testing documentation. It describes breeding methods, such as the hybridization of the parent species Lolium perenne and Lolium multiflorum, and is not a measurable quantitative indicator.
This passport trait determines the biological properties of the cultivar, including growth habit, regrowth rate, and winter hardiness. Agronomic qualities depend on the genetic contribution of the parental forms: types similar to perennial ryegrass create a denser turf, while Italian ryegrass types exhibit intensive growth.
