This is a synthetic variety derived from the crossing between plants selected from long-lived alfalfas that belong to intermediate-rest cultivars with a 42% composition of North American and Australian germplasm and 52% of Argentinian germplasm. The mother plants were chosen from fields under cropping or grazing in the south of the province of Córdoba, central area of La Pampa province, and east of San Luis province. The selection criterion used was the high forage production and persistence, plant vigour after 4 years of intake, absence of symptoms of crown and root diseases, and resistance to aphids.
It has very good persistence and adapts to the south of the province of Córdoba, central and western area of Buenos Aires province, La Pampa, San Luis and rest of the Argentinian Patagonia.
Suitable for haymaking (hays, silage or haylage).
