Details for: PI 671851, Bromus inermis Leyss., 'Newell'

`Newell? smooth bromegrass was released by USDA-ARS and the Univ. of Nebraska-Lincoln in 2014. Newell is a pasture type smooth bromegrass that is adapted in the USA to areas north of 40o N lat and east of 100o W long that have 500 mm or more annual precipitation or in areas that have similar climate conditions because of elevation. Newell was developed to replace the most widely used smooth bromegrass cultivar, Lincoln, by improving its forage digestibility. Newell can produce forage with higher digestibility as measured by in vitro dry matter digestibility (IVDMD) than Lincoln smooth bromegrass, it can produce equivalent or greater forage yields, and when utilized by beef cattle in grazing studies, Newell produced significantly greater average daily gains and gains per hectare. Newell is named after pioneer grass breeder, L. C. Newell. Newell bromegrass was developed by four generations of population improvement breeding by K.P. Vogel. The cultivar Lincoln was used as the base population. Principal selection criteria were forage yield and IVDMD. Each breeding generation was about five years. Newell was tested as Lincoln HYLD-HDMD C4 in multi-location small plot trials and in a replicated grazing trial in eastern Nebraska. Newell smooth bromegrass is a stable, improved random mated population and will be maintained and increased accordingly. Because of its genetic background, it is similar to Lincoln in appearance and maturity. 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 Syn 1 breeder seed harvested from the Cycle 4 polycross nursery. Foundation seed production of Newell will be managed by Husker Genetics, the Foundation Seed Division of the University of Nebraska-Lincoln, Lincoln, NE.
