Festulolium tiller density

x Festulolium Aschers. et Graebn.

Festulolium tiller density is a biological trait that determines the number of vegetative tillers per plant, which directly influences stand density, winter hardiness, and total crop productivity.

In the reference 4 varieties crop Festulolium, where this is mentioned in the description.

The trait is evaluated by counting the number of well-developed tillers per plant. In the first year of growth before winter dormancy, plants typically form 5 to 8 shortened vegetative tillers; however, tiller density increases significantly as the stand ages.

Tiller density values show high variability: in the second year of growth, values range from 6 to 90 tillers, and in the third year, from 33 to 160 tillers per plant. In breeding practice, certain varieties, such as 'Udzhyachny', have shown values reaching 280 tillers per plant.

High tiller density contributes to the formation of a dense sward and maximum biomass yield. This parameter depends on growing conditions: as the area of nutrition and the availability of mineral nutrients increase, tiller density rises, whereas thickened stands can lead to a decrease.
