'Hallam', selected from the cross 'Brule'/'Bennett'//'Niobrara', is a hard red winter wheat (Triticum aestivum) cultivar developed cooperatively by the Nebraska Agricultural Experiment Station and the USDA-ARS. It was released in 2005 primarily for its superior adaptation to rainfed wheat production systems in eastern Nebraska. The average Nebraska rainfed yield of Hallam of 4110 kg/ha (41 environments from 2002 to 2004) was greater than 'Wahoo' (4030 kg/ga), 'Alliance' (3880 kg/ha) and 'Harry' (4000 kg/ha), but lower than 'Millenium' (4180 kg/ha) and 'Wesley' (4210 kg/ha). Hallam is moderately early in maturity (142 days after 1 January), approximately 2.5 and 1.2 days earlier than Millenium and Wesley, respectively. It is a semidwarf cultivar with a medium short coleoptile (46 mm) and mature plant height (86 cm) that is 3 cm shorter than Millenium and 6 cm taller than Wesley. Hallam is moderately resistant to stem rust (Puccinia graminis f.sp. tritici), stripe rust (P. striiformis f.sp. tritici) and Hessian fly (Mayetiola destructor).
