Interpretive Summary: A commonly held myth often voiced by those ignorant of the true status of wheat breeding is that all modern wheats contain dwarfing genes and are highly dependent upon high nitrogen inputs. Nothing could be further from the truth. In the more arid regions of the western Great Plains of the U.S., traditional tall (e.g. non semi-dwarf) wheats are still produced. Tall plant stature often is associated with long-coleoptiles, a trait essential to seedling establishment under dry conditions. Tall plant stature also is desired by farmers for dryland wheat production, as the extra height is beneficial during mechanical harvesting, and the extra straw produced may be used to feed livestock or enrich the soil and prevent weed growth in reduced tillage systems. As part of an effort to provide U.S. wheat farmers with a continuous source of high yielding tall wheats, the cultivar Goodstreak was developed. Goodstreak combines high yield potential, drought tolerance, tall plant height and long coleoptiles, and will be available to Great Plains wheat producers in the fall of 2003.

Technical Abstract: Goodstreak¿ (Reg. No. Cv- , PI ) 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 2000 by the developing institutions and the Wyoming Agricultural Experiment Station. Goodstreak was released primarily for its superior adaptation to rainfed wheat production systems in western Nebraska where conventional height wheat cultivars with long coleoptiles are needed for good emergence and harvest in low moisture conditions. The name was chosen because the area in which it will most likely be grown is known as ¿Goodstreak¿ because the grasslands were better than the surrounding areas. In this area, drought is common and ¿Goodstreak¿ is an indication that water use efficient annual crops, such as wheat can be grown. Goodstreak was selected from the cross `SD3055/KS88H164//NE89646 that was made in 1991. The pedigree of SD3055 is ND604/SD2971 where ND604 is `Len¿//¿Butte¿/ND526 and SD2971 is `Agent¿/3/¿ND441¿// `Waldron¿/¿Bluebird¿/4/Butte/5/Len. The pedigree of KS88H164 is `Dular¿/¿Eagle¿//2*¿Cheney¿/¿Larned¿ /3/¿TAM107¿. The pedigree of NE89646 is `Colt¿ *2/¿Patrizanka¿. The F1 to F3 generations were advanced using the bulk breeding method. Goodstreak is an F3-derived line that was selected in the F4 generation.
