“…PI 471938 was also previously identified as expressing N 2 fixation tolerance to soil drying (Sinclair et al 2000;Devi and Sinclair 2013;Riar et al 2018). These two plant introductions are being used as sources of slow wilting in applied breeding programs (Devi et al 2014;Carter et al 2016). Two additional MG III PIs were also previously identified that have reduced yield loss under drought stress and delayed leaf wilting (Pathan et al 2014).…”

“…There are approximately 170,000 soybean accessions maintained in germplasm collections worldwide, and the USDA maintains a collection of around 20,000 accessions. However, only a limited number of these genotypes have been screened for stress tolerance, and few have been identified as tolerant and used in soybean breeding programs to improve drought tolerance (Carter et al 1999(Carter et al , 2004(Carter et al , 2016Devi et al 2014;Sinclair et al 2016). Identification of new accessions with beneficial alleles for drought tolerance related traits, including slow canopy wilting, could help in the development of drought tolerant soybean cultivars.…”

Drought stress causes the greatest soybean [Glycine max (L.) Merr.] yield losses among the abiotic stresses in rain-fed U.S. growing areas. Because less than 10% of U.S. soybean hectares are irrigated, combating this stress requires soybean plants which possess physiological mechanisms to tolerate drought for a period of time. Phenotyping for these mechanisms is challenging, and the genetic architecture for these traits is poorly understood. A morphological trait, slow or delayed canopy wilting, has been observed in a few exotic plant introductions (PIs), and may lead to yield improvement in drought stressed fields. In this study, we visually scored wilting during stress for a panel of 162 genetically diverse maturity group VI-VIII soybean lines genotyped with the SoySNP50K iSelect BeadChip. Field evaluation of canopy wilting was conducted under rain-fed conditions at two locations (Athens, GA and Salina, KS) in 2015 and 2016. Substantial variation in canopy wilting was observed among the genotypes. Using a genome-wide association mapping approach, 45 unique SNPs that tagged 44 loci were associated with canopy wilting in at least one environment with one region identified in a single environment and data from across all environments. Several new soybean accessions were identified with canopy wilting superior to those of check genotypes. The germplasm and genomic regions identified can be used to better understand the slow canopy wilting trait and be incorporated into elite germplasm to improve drought tolerance in soybean.

“…For the analysis of agronomic data from the South Dakota CPT, least square mean estimates were determined within each environment (year–location combination) separately using PROC MIXED. Least square means from each environment were then used to compute entry mean for each year and across all environments using a method similar to Carter et al (2016). Data from the UMOPN were only available as entry‐mean average over locations, and quality data from the SD CPT were unreplicated; therefore in both cases, the genotype × environment interaction component was confounded with error variance.…”

Despite a signiicant decrease over the last 50 years, the production of oats (Avena sativa L.) presents both environmental and health beneits. When incorporated in crop rotations, oat has the potential to improve soil health and to break pest cycles in corn (Zea mays L.)-soybean [Glycine max (L.) Merr.] rotations. In addition, the presence of a soluble dietary iber (b-glucan) in oat grain can help prevent cholesterol, coronary heart diseases, and type 2 diabetes. The development of new oat cultivars with superior productivity and high test weight is required to improve the attractiveness of the crop to producers and to maintain or increase oat production in the United States. 'Hayden' (Reg. No. CV-383, PI 676028) is a spring oat cultivar developed at South Dakota State University and released by the South Dakota Agricultural Experiment Station in 2014. The pedigree of Hayden is 'Buckskin'//ND011054/SD020835. Hayden was developed using a modiied bulk and single seed descent selection method. Hayden is a white hulled cultivar with mid-to-late maturity. Hayden was evaluated in the South Dakota Crop Performance Testing Oat Variety Trial from 2013 to 2015 and in the Uniform Mid-Season Oat Performance Nursery in 2013 and 2014 under the experimental number SD111972. Hayden was released because of its excellent yield potential, good yield stability, and high test weight. It is resistant to smut and moderately tolerant to Barley yellow dwarf virus. Hayden also demonstrates good overall milling and nutritional quality. Agronomy, Horticulture, and Plant Science Dep., South Dakota State Univ., Brookings, SD.O at (Avena sativa L.) grain production in the United States has declined signiicantly over the last 50 years. he Upper Midwest accounts for a large proportion of US oat production. With 183.27 million kg produced in 2015 (USDA National Agricultural Statistics Service, 2015), South Dakota is one of the main oat producing states in the United States. Including spring oats in corn (Zea mays L.)-soybean [Glycine max (L.) Merr.] rotations presents an advantage because it can break pest cycles and improve soil health. Oat grain is used mainly for feed and for food. he race horse feed market requires white-hulled cultivars with high test weight. To meet the requirement of the food market, it is desirable that new cultivars exhibit high test weight, high groat percentage, and high thousand kernel weight, as well as demonstrate a b-glucan concentration higher than 4%. Because oat grains contain b-glucan, a soluble iber promoting health beneits, the market for milling quality oats is increasing. To ensure that food products made with oats remain afordable for consumers, it is necessary to maintain or increase oat production. To increase the attractiveness of oats to farmers in the region, new oat cultivars must be developed with improved productivity and marketability. he objective of the South Dakota State University breeding program was to develop a new white-hulled oat cultivar with increased grain yield, high test weight, and ...

“…The first drought‐tolerant germplasm releases in the United States were R01‐416F and R01‐581F (Chen et al., 2007). Recently, a maturity group (MG) 8 cultivar, ‘USDA‐N8002’ (Carter, Todd, & Gillen, 2016), was released for its high yield, drought tolerance, and diverse pedigree derived from Asian drought‐tolerant soybean types. Devi, Sinclair, Chen, and Carter (2014) reported the expression of drought tolerance traits in elite breeding lines developed at the University of Arkansas and the USDA‐ARS, Raleigh, NC.…”
