“…In addition, isolation and characterization of other players in this complex pathway may help us decipher the complexity of this pathway. (Clark et al, 1926). The resulted F 2 population was grown under controlled conditions in a growth chamber under 16 h day (18℃) and 8 h (14℃) night.…”

The wheat reduced height genes (Rht) played an important role in "The Green Revolution" by reducing damage due to lodging and making wheat more responsive to fertilizer applications. The successful use of cultivars containing Rht-B1b and Rht-D1b around the world compelled the scientist to identify and generate height mutants through induced mutation in wheat. There are manyRht genes known in wheat, however genetic and molecular characterization of many Rht genes are lacking. The Rht3 gene was originally found in the cultivar, Tom Thumb, and resulted in 46% reduction in plant height compared to the wild type allele, rht3. The objectives of our investigation were to identify SSR markers linked to Rht3 and to develop a genetic linkage map of the region containing the Rht3 gene. The Rht3 gene was located on chromosome 4B using bulked segregant analysis. Genetic linkage mapping using an F2 population placed Rht3 between markers wmc125 and gwm149 with a genetic distance of 14.4 cM and 23.6 cM, respectively. Identification of SSR markers associated with Rht3 may help breeders to more efficient screen for reduced height genes in breeding programs with diverse environmental conditions.

“…Most of the germplasm have awned spikes, bright grain chaff, and semi-dwarf stature. Among the germplasm, Cheyenne (CItr 8885; Clark, 1931), Kharkof (CItr 6700; Clark et al, 1926a), Turkey (plant introduction [PI] 11610; Clark et al, 1926b), and Wichita (CItr 11952; Clark, 1945) are historically important parents of many hard red winter wheat breeding programs in the United States (Fufa et al, 2005).…”

Genetic Diversity of Great Plains Hard Winter Wheat Germplasm for Forage

et al. 2016

Wheat (Triticum aestivum L.) has been widely grown for winter forage production across the world. However, improvement of forage yield and nutritive characteristics has not been a major goal of wheat breeding programs, and little is known about genetic diversity in the traits of winter wheat germplasm. A set of 299 hard winter wheat germplasm from the Great Plains was evaluated during two growing seasons in Oklahoma and 15 forage‐related traits were evaluated. There were significant (P < 0.0001) genetic variations in all the traits but effects of environment and germplasm × environment interaction were significant for seven and eight traits, respectively. A significant portion of the variation for forage traits was due to genetics, indicating an ability to breed for improved forage traits. Dry matter yield (DMY, kg ha−1) of the germplasm ranged from 1260 for Cheyenne to 4158 for Sturdy2K. Crude protein (CP, g kg−1) ranged from 161 for OK05108 to 268 for Nuplains. When crude protein yield (kg ha−1) was considered, Sturdy2K was the best germplasm, followed by 2180 and OK1068009. State of origin of the germplasm was also a significant source of variation for most of the traits. Heading date was positively and negatively associated with CP and DMY, respectively. This study identified significant genetic variations of the hard winter wheat germplasm for forage traits and the results of this study could provide useful guidelines for winter forage wheat breeding programs.

“…For hay production, livestock producers have favored awnless small grain cultivars including oat ( Avena sativa L.), hooded or awnless barley ( Hordeum vulgare L.), and awnletted wheat. In Montana and the Northern Great Plains, Beardless Kharkof (USDA‐ARS NPGS, 2008a), ‘Montana King’ (Clark, 1936), and ‘Newturk’ (Clark et al, 1926) are examples of early landraces or cultivars of awnless wheat used for forage. Many new seed sources of “beardless” and awnletted winter wheat and triticale (× Triticosecale Wttm.)…”

‘Willow Creek’ forage winter wheat (Triticum aestivum L.) (Reg. No. CV‐1032, PI 655073) was released by the Montana Agricultural Experiment Station. Awnletted cereal forages are widely used for hay production on integrated crop–livestock operations in the Northern Great Plains. Five awnletted winter wheat accessions were evaluated for forage characteristics in 1996 and 1997, and Willow Creek was selected directly from PI 306505. Willow Creek was evaluated in replicated trials for forage yield and quality, grain yield, and agronomic characteristics from 1998 through 2008. Willow Creek is an awnletted winter wheat cultivar with good performance as an annual hay crop under irrigated or rainfed conditions in Montana and Wyoming. This cultivar has excellent winterhardiness and is tall and late‐maturing. Willow Creek has good forage quality characteristics suitable for use by livestock in winter maintenance diets.
