Narrative
Scout indiangrass was developed by the Agricultural Research Service (ARS), U.S. Dept. of Agriculture (USDA) and was jointly released by USDA-ARS and the Agricultural Research Division, Institute of Agriculture and Natural Resources, University of Nebraska-Lincoln. Scout is adapted to USDA Plant Hardiness Zone 5 (HZ 5) in the Great Plains and Midwest, USA and potentially other regions where it has not been tested to date. 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. Scout 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 2 polycross nursery. Foundation seed production of Scout 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 Scout. Certified seed production will be restricted to the USDA Plant Hardiness Zone 5 where the cultivar is adapted

Pedigree
Description:
Scout was developed by 2 cycles of recurrent breeding for improved forage yield and in vitro dry matter digestibility using the cultivar Nebraska 54 as the base population. The breeding method was restricted recurrent mass selection. Selected plants were intermated in isolation to produce seed to start the next cycle. Each cycle took approximately five years. After cycle 2, seed was increased for small plot trials and a grazing trial. Scout was evaluated and tested as NE 54 C2.
