Crop Science. 46: 977-979. Interpretive Summary: ‘Hallam’ is a new hard red winter wheat cultivar jointly developed by the University of Nebraska Lincoln and the United States Department of Agriculture, Agricultural Research Service. Hallam is adapted to dryland conditions in southeastern Nebraska, and has improved grain yield production relative to the hard red wheat cultivar Wesley, currently the most widely grown wheat in this area. It complements Wesley genetically, having few genes in common. Hallam provides farmers in southeastern Nebraska and adjacent areas a new cultivar with proven grain performance, and end-use quality acceptable for the production of typical wheat products.
Technical Abstract: ‘Hallam’ (PI 638790) is a hard red winter wheat (Triticum aestivum L.) cultivar developed cooperatively by the Nebraska Agricultural Experiment Station and the USDA-ARS and released in 2005 by the developing institutions. Hallam was released primarily for its superior adaptation to rainfed wheat production systems in eastern Nebraska. Hallam was selected from the cross ‘Brule’/’Bennett’//’Niobrara’ that was made in 1992. In the Nebraska cultivar performance trials, it appears to be narrowly adapted and performs best in eastern Nebraska. The average Nebraska rainfed yield of Hallam of 4110 kg ha-1 (41 environments from 2002 to 2004) was greater than the yields of ‘Wahoo’ (4030 kg ha-1), ‘Alliance’ (3880 kg ha-1), and ‘Harry’ (4000 kg ha-1), but was lower than ‘Millennium’ (4180 kg ha-1), and ‘Wesley’ (4210 kg ha-1). In its primary area of adaptation (eastern NE), Hallam (5 environments) has yielded 4540 kg ha-1, which was greater than Wesley (4150 kg ha-1), Millennium (4250 kg ha-1), Wahoo (3940 kg ha-1), and Alliance (3900 kg ha-1).
