Narrative
Selection Cycle 1: Selection pressure consisted of germinating 3,500 pure-seeds of AB-medium Syn-O in deionized water having a water potential of -0.8 MPa" for seven days. At the end of seven days, all germinated seed (approximately 250 seeds) were removed, washed with deionized water, planted into cavity trays containing a greenhouse soil mix, and maintained in the greenhouse until field planting. Seeds were considered germinated if the seedling root and shoot were at least 1 mm long. The selected populations was transplanted to the field in a polycross isolation plot where plants were allowed to grow and produce the next generation seeds designated as either AB-medium Syn-l. Selection Cycle 2: Approximately 3,500 pure-seed of population AB-medium Syn-l were germinated in deionized water having a water potential of -0.8 MPa for seven days. At the end of seven days, all germinated seed (approximately 250 seeds) were removed, washed with deionized water, planted into cavity trays containing a greenhouse soil mix, and maintained in the greenhouse until field planting. Seeds were considered germinated if the seedling root and shoot were at least I mm long. The selected population was transplanted to the field in a polycross isolation plot where plants were allowed to grow and produce the next generation seeds designated as either AB-medium Syn-2. The germination and seedling emergence of popUlation AB-medium Syn-2 (Centennial) was consistently superior to population AB-medium Syn-O. And forage dry-matter yield, forage CP, and forage IVDMD did not differ among bluestem populations (AB-medium Syn-O, AB-medium Syn-l, or AB-medium Syn-2). The average annual seed production from non-replicated field plots of A B-Medium Syn-2 was 47 kg ha-I. Centennial is a stable, random mating population improved for increased seed germination and seedling emergence. It was tested in and is adapted to USDA Plant Hardiness Zones 5b, 6, and 7a of the Central and Southern Great Plains of the USA. Upon additional testing it may be adapted to other regions as well. Breeder's and Foundation seed will be maintained by the USDA-ARS. Certified seed production of Centennial will be limited to a single generation and can only be marketed as Centennial. Certified seed production will be limited to USDA Hardiness Zone 5b, 6 or 7a in its known adaptation range in the Central and Southern Great Plains region. Seed of Centennial will be deposited in the USDA-ARS National Plant Germplasm System (NPGS). Appropriate recognition is requested if this release contributes to the development of new breeding line or cultivar. Centennial was named to signify the first 100 years (1913-2013) of USDA agricultural research at Woodward, OK. Selection and testing of Centennial was accomplished through a cooperative effort of USDA-ARS and USDA-NRCS and included the following individuals: Tim Springer (lead scientist), William Cooper, Emalee Friend, Richard Wynia, Rudy Esquivel, and Gary Rea.

Pedigree
Description:
Seeds from sand bluestem population' AB-medium Syn-O' were harvested and cleaned to produce a chaffy-seed product of98% pure seed. AB-medium Syn-O was originally selected for growth and regrowth, disease incidence, leafiness, seedling vigor, and plant height at the USDA-ARS Southern Plains Range Research Station, Woodward, OK. AB-medium Syn-O was released as 'Chet' sand bluestem in 2004.
