Nash] is a cultivar that is adapted to USDA Plant Hardiness Zone 5 (HZ 5) and the upper part of Plant Hardiness Zone 6 in the Great Plains and Midwest, USA and potentially other regions where it has not been tested to date. It produces forage with high in vitro dry matter digestibility (IVDMD) that results in improved animal gains when utilized by beef cattle in well managed grazing systems in regions where it is adapted. In the same regions, Warrior could be used in mixtures with other grasses to produce biomass for bioenergy. Warrior is similar in maturity to Oto and Scout in both swards and space-planted nurseries. It is about 7 days earlier in heading date (date when inflorescence is fully exerted from the boot) than Rumsey and Osage in swards. Warrior is about 6 days later than maturity than Nebraska 54 when evaluated in swards. Warrior is a stable, improved random mated population and will be maintained and increased accordingly. Breeder seed will be jointly maintained and produced by USDA-ARS and the University of Nebraska-Lincoln with random-mated, isolated increase fields originating from the Syn 2 breeder seed produced from the cycle 3 polycross nursery. Foundation seed production of Warrior will be managed by Husker Genetics, the Foundation Seed Division of the University of Nebraska-Lincoln, Lincoln, NE. Foundation seed will be made available for certified seed production on a non-exclusive basis to seed producers who contractually agree to produce and market the seed only as certified seed using the cultivar name Warrior.

It produces greater forage yields than other adapted indiangrass cultivars when grown for hay in the western part of Plant Adaptation Region 251-5 (Prairie Parkland Temperate HZ 5). In comparisons to its parent cultivar, it produces improved animal gains when utilized by beef cattle in well managed grazing systems in regions where it is adapted. In the same regions, Scout could be used in mixtures with other grasses to produce biomass for bioenergy. Scout is 6 days earlier in heading date than Nebraska 54 in swards but is similar in maturity in space-planted nurseries. Scout is 8 days earlier in heading date than Rumsey and Osage, similar to Oto and Warrior, 20 days later than Holt, and 10 days later than Chief.

Indian grass grows 3-5 ft tall. Even as a young plant, it can be distinguished from other native grass species by the rifle-sight ligule at the point where the leaf attaches to the stem. The leaf blade also narrows at the point of attachment. The seed head is a single, narrow, plume-like panicle of a golden brown color. The seed is light and fluffy with small awns attached. Suther Germplasm Indian grass is recommended for roadside revegetation, critical area, wildlife habitat, parks, recreational areas, landscapes, and prairie restoration. Indiangrass can provide hay and forage to all classes of livestock. Its forage rates good to excellent if plants are utilized in the leafy stage and before seed head emergence. It is an important part of prairie pastures and is considered a long-lived perennial. This release is recommended for planting throughout the mid-Atlantic area of the Eastern United States. | 1694878 | PI 675555 |
