where this is mentioned in the description.
For perennial ryegrass, varieties are categorized into early-maturing, mid-maturing, and late-maturing based on the evaluation of the rate at which key developmental stages occur, primarily the onset and completion of heading. In breeding practice, this indicator is determined by the number of days from the start of spring vegetation to the onset of the generative phase.
The maturity group of a variety is a determining factor when planning agrotechnical measures, as the nutritional value of green biomass directly depends on the plant's growth stage. The use of varieties with asynchronous growth rhythms allows for the creation of a continuous green conveyor, optimization of mowing campaign timelines, and the appropriate selection of components for perennial grass mixtures.
