Interpretive Summary:

Technical Abstract: ‘Endurance’ is a hard red winter wheat (Triticum aestivum L.) that was released to certified seed growers with permission of the Oklahoma Agricultural Experiment Station and the USDA-ARS in 2004. Its name derives from the unique ability to endure and recover from extended and intensive grazing in a dual-purpose management system common to Oklahoma and surrounding states. Endurance is positioned for irrigated and dryland production areas throughout the southern Great Plains. Endurance originated in the former hard red winter (HRW) wheat breeding program of Pioneer Hi-Bred International, Inc. from the three-way cross HBY756A/’Siouxland’//’2180'. HBY756A and the HRW cultivar, 2180 (PI 532912), were both developed within the Pioneer program. HBY756A is an unreleased germplasm with the incomplete pedigree, TAM 105/4/Bobito ‘S’/3/unknown SRW parent//unknown SRW parent/unknown parent, in which SRW designates a soft red winter wheat. Siouxland was developed and released by the University of Nebraska-Lincoln. The F1 and subsequent bulk generations were evaluated within the Pioneer program. The parent line from which Endurance is derived originated as an F4:5 head row selected at Manhattan, KS in 1990 and grown in the “Pioneer Short Rows-1" nursery at Manhattan and Hutchinson, KS in 1991. It was then entered in the 1992 Pioneer Observation Nursery, submitted to cooperating breeding programs in the Great Plains in the fall of 1991 by Dr. R. G. Sears. This nursery contained 140 early-generation lines developed by Pioneer. From one of two sister lines both named HBG0624, OK94P549 was selected and named as OK94P549 in 1994. After three years of multi-environment testing in Oklahoma, 200 heads were selected from a breeder-seed increase plot of OK94P549 in 1996 to identify re-selected lines with improved phenotypic uniformity. OK94P549-11 is an F11-derived line that traces to a single head row in 1997. It was evaluated in Oklahoma State Univ. breeder nurseries from 1999 to 2003 and in the Southern Regional Performance Nursery (SRPN) in 2003. It was subsequently tested in the Oklahoma Wheat Variety Trials (OWVT) from 2003 to 2005. Endurance is a moderately tall semidwarf wheat with late arrival to first-hollow-stem (FHS) stage and intermediate maturity. From 2003 to 2005 at Stillwater, OK, Endurance reached FHS stage 7 d later than ‘Ok101' and 15 d later than ‘Jagger’. Heading date of Endurance, however, is only 2 d later than Ok101 and 3 d later than Jagger. This combination of late FHS stage and intermediate heading date provides a crucial fitness trait for maximizing economic returns from grazing and grain production in a dual-purpose management system. Other fitness traits relative to a dual-purpose system include a semi-prostrate fall growth habit (slightly more decumbent than Ok101 but more erect than Jagger, moderately fine canopy texture in the fall (similar to Jagger) with a narrow and short leaf blade, and excellent fall forage production based on clipping trials in 2004.
