“…The DH lines were developed from F 1 plants of the cross between cultivar WI and chromosome substitution line WI(CNN3A). Wichita is a hard red winter wheat developed in 1944 at Kansas State University (Clark, 1945) and was extensively used in numerous breeding programs for wheat improvement in the Great Plains. The chromosome substitution line WI(CNN3A) was developed by substituting chromosome 3A of cultivar WI with chromosome 3A of cultivar CNN, a hard red winter wheat developed in 1933 at the University of Nebraska (Clark, 1931) and a major cultivar used in many Great Plains wheat improvement programs.…”

Previously, quantitative trait loci (QTLs) for grain yield (GYLD) and yield-related traits were identified by using a population of recombinant inbred chronnosome lines (RICLs) developed from the wheat {Triticum aestivum L.) eultivar Cheyenne (CNN) and its substitution line CNN(WI3A), in which the 3A chromosome of eultivar Wichita (Wl) was substituted for CNN chromosome 3A. Our objectives were to identify and validate the QTL previously identified in CNN(RICLs3A), using the mirror population WI(RICLs3A). A population of 90 WI(RICLs3A) was used to evaluate GYLD, 1000-kernel weight (TKW), kernels per spike (KPS), kernels per square meter (KPSM), spikes per square meter (SPSM), grain volume weight (GVW), plant height (PHT), and anthesis date (AD). Data were collected from replicated trials grown in six Nebraska environments from 2008 to 2009. Twelve QTL for GYLD, TKW, KPS, SPSM, GVW, AD, and PHT were detected. The phenotypic variance explained by these QTL ranged from 12% for SPSM to 53% for GVWT Most of the QTLs were co-localized in one or two regions of chromosome 3A. The major grain yield QTL {QGyld.neb.3A.1) detected in the combined analysis explained 19% of the phenotypic variance and the substitution of CNN alíeles for Wl alíeles decreased grain yield. Using a different genetic background, this study confirmed most of the GYLD and yield-related QTL reported in previous RICLs3A mapping studies on chromosome 3A of winter wheat evaluated in Nebraska.

“…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.

“…It was the foundation cultivar for hard red winter wheat in the Great Plains (Smith, 1995). "Cheyenne," a selection from "Crimean" (Clark, 1931), is believed to be the foundation of the Nebraska wheat improvement project and is an ancestor of many prominent cultivars. "Warrior" is a predominant parent of "Siouxland," "Centurk 78," and "Centura."…”
