Variety traits

Leafiness — Perennial ryegrass

Lolium perenne L.

An indicator of the proportion of leaf mass in the total yield of perennial ryegrass, which determines its nutritional value. In highly leafy cultivars, the value of this trait exceeds 70%.

In the reference 23 varieties crop Perennial ryegrass, where this is mentioned in the description.

The leafiness of perennial ryegrass is measured as the percentage of leaf blades and sheaths in the total air-dry plant mass. In breeding practice, accessions with values ranging from 67.2% to 72.9% are considered highly productive, with values above 70% characterizing the crop as highly leafy.

A high proportion of leaves ensures an increased content of protein and sugars, which is critical for feed quality. Intensive formation of vegetative tillers contributes to maintaining leafiness; however, as the plant transitions to the flowering phase and forms generative stems, this indicator decreases, requiring timely mowing of the grass stand.
