Abstract

Abstract : 'Newell' (Reg. No. CV‐275, PI 671851) smooth bromegrass ( Bromus inermis Leyss.) is a steppe or southern type cultivar that is primarily adapted in the United States to areas north of 40° N and east of 100° W that have 500 mm or more annual precipitation or in areas that have similar climatic conditions because of elevation or latitude. It was developed to replace 'Lincoln', which is the most widely used smooth bromegrass cultivar in the region, by improving its forage digestibility. Newell bromegrass was developed by four generations of population improvement breeding for in vitro dry matter digestibility (IVDMD) and forage yield using Lincoln as the base population. In regional small plot trials, Newell produced forage with greater IVDMD than Lincoln and equivalent or greater forage yields. In a replicated grazing trial in eastern Nebraska, beef yearlings grazing Newell for a 3‐yr period produced significantly greater average daily gains and beef production per hectare than yearlings grazing Lincoln bromegrass.
