Jumbo is a new tetraploid annual ryegrass bred by the famous University of Florida ryegrass breeder, Dr. Gordon Prine. Jumbo is a new generation tetraploid that combines superior rust resistance with great cold tolerance. It is a late maturing variety maximizing the growing season. Jumbo impresses with its vigorous growth and high yields throughout the South. The variety is suited for mechanical harvesting (silage) as well as grazing.
Annual ryegrass establishes very rapidly, which gives high productivity in the planting season. This species is mainly used for overseeding warm season pastures in the fall. Annual ryegrass is capable of producing high forage yields in a very short period of time.
