The "Allegro" variety belongs to the Festulolium family and represents a perennial grass with high feed value. In the autumn period after sowing, the plant has a semi-upright form, leaves of medium length and width, and in the spring retains the same structure, reaching a height of about 100–120 cm.
The yield of this variety is consistently high: green mass is 250 to 300 centners per hectare, and seeds are 7–9 c/ha. Crude protein content is at the level of 11%, and crude fiber is 26%. These indicators make "Allegro" attractive for the production of bulky feeds and silage preparations.
The variety is distinguished by good winter hardiness, high germination (≈88%) and seed purity of about 98%. It is easily silaged due to the high content of carbohydrates at the stage of coming out of the sheath. "Allegro" is suitable for use as a forage grass and pasture material, providing stable feed for animals even during cold periods of the year.
