Interpretive Summary: NE01643, to be marketed under the trademarked name Husker Genetics Overland, is a hard red winter wheat with high grain yield potential, excellent resistance to stress and current prevalent leaf diseases, and good straw strength. Grain oOne of its parents is the highly successful hard red winter wheat Millennium. In the USDA-ARS coordinated Northern Regional Performance Nursery, grown at sites from Kansas to Canada, NE01643 ranked in 1st grain yield in both 2004 and 2005. In the 2004 trial, NE01643 averaged 75 bushels/acre, while the check cultivars Harding and Nekota averaged 68 and 60 bushels/acre, respectively. In 2005, respective average grain yields of Ne01643, Nekota and Harding were 65, 49 and 41 bushels/acre. NE01643 is adapted to dryland production systems across the states of Nebraska, South Dakota and North Dakota. Grain yield under irrigated conditions is not as high as that of alternative culitvars; hence, it is not recommended for irrigated production. NE01643 offers wheat producers of the northern Great Plains a new source of high grain production across diverse environmental conditions.
Technical Abstract: NE01643 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 2007 by the developing institutions and the South Dakota Agricultural Experiment Station. NE01643 will be marketed under the name Husker Genetics Brand Overland in honor of the pioneers who crossed and stayed in the northern prairies. NE01643 was selected from the cross Millennium sib//Seward/Archer that was made in 1995. NE01643 was evaluated in Nebraska replicated yield nurseries starting in 2002, in the Northern Regional Performance Nursery in 2004 and 2005, and in Nebraska cultivar performance trials in 2004 to 2006. In the Nebraska cultivar performance trials, it is widely adapted and performs well throughout the state (Table 1) with the exception of irrigated wheat production systems where it performs near the average of the tested lines. The average Nebraska rainfed yield of NE01643of 4072 kg ha-1 (39 environments from 2004 to 2006) was greater than the yields of other popular cultivars such as Antelope (3353 kg ha-1), Goodstreak (3653 kg ha-1), Harry (3556 kg ha-1), Infinity CL (3919 kg ha-1), Agripro Brand Jagalene (4028 kg ha-1), Millennium (3815 kg ha-1), Wahoo (3662 kg ha-1), and Wesley (3719 kg ha-1). In positioning NE01643, based on performance data to date, it should be well adapted to most rainfed wheat production systems in Nebraska and South Dakota, and in adjacent areas of the northern Great Plains. Being a broadly adapted wheat line may explain its excellent agronomic performance in the Northern Regional Performance Nursery.
