USDA‐N7007 is a non‐GM, maturity group (MG) VII soybean [Glycine max(L.) Merr.] (Reg. no. GP‐529, PI 705147) germplasm released by the USDA Agricultural Research Service in conjunction with the North Carolina Agricultural Research Service in December of 2023. USDA‐N7007 is a high‐yielding, high‐protein germplasm derived from wild soybean (Glycine sojaSiebold & Zucc; PI 366122) and small‐seeded MG VII USDA cultivar N7103. Over 47 combined testing environments of the USDA Southern Uniform and USB Protein Diversity Tests (2018–2021), USDA‐N7007 yielded 98% of the check mean and 102% of the test mean. The average protein content of USDA‐N7007 was significantly higher (432 g kg−1) than the average check means of 402 g kg−1and 413 g kg−1in the USDA Southern Uniform and USB Protein Diversity Tests, respectively. Across both tests (2019–2021), the release was significantly (p< 0.05) higher in protein (+7 g kg−1), with 9% higher seed yield (+242 kg ha−1) than the recurrent parent N7103. USDA‐N7007 is resistant to lodging, southern root‐knot nematode, and stem canker. To the best of our knowledge, this is the first US release clearly demonstrating that the wild soybean genome can be incorporated into an elite cultivar to increase seed protein without a negative effect on seed yield. This release is a truly novel and valuable resource for development of future US soybean cultivars because it will be useful to improve both genetic diversity and seed protein simultaneously without a negative effect on seed yield. USDA‐N7007 demonstrates that wild soybean can be used in cultivar development without a yield drag.USDA‐N7007 is a valuable resource for development of future soybean cultivars to improve genetic diversity.USDA‐N7007 exhibits an increased protein content without a negative effect on yield.Expanding the genetic base of soybean is a vital factor for increasing sustainability.

USDA‐N6006 soybean [Glycine max(L.) Merr.] (Reg. no. GP‐527, PI 704140) is a conventional F4–derived early maturity group (MG) VI germplasm jointly released by USDA‐ARS and North Carolina Agricultural Research Service in 2023. USDA‐N6006 is the first MG VI, publicly released germplasm that combines flood tolerance with high‐yield lodging resistance, and elevated seed oil. Over 19 environments of the MG VI USDA Southern Uniform Soybean Trials (2017–2018), seed yield of USDA‐N6006 (3393 kg ha−1) was similar to high‐yielding lodging‐resistant check cultivars ‘NC‐Dunphy’ (3427 kg ha−1) and ‘NC‐Dilday’ (3475 kg ha−1). It matured 1 day earlier than NC‐Dunphy and exhibited similar lodging scores. Over 5 years of testing in North Carolina (2016–2019), USDA‐N6006 exhibited very robust flood tolerance. Mean flooding scores were numerically or statistically (p< 0.05) superior to the four flood‐tolerant controls at both V4 and R1 growth stages. USDA‐N6006 was not intentionally bred to be flood tolerant and identified as such only through an extensive screening of “in house” USDA breeding lines. USDA‐N6006 and most of its antecedents are unique in that they are derived from unreleased breeding lines developed at the flood prone Tidewater Research station in North Carolina. Inadvertent selection for flood tolerance may have been a part of the USDA's long‐term breeding effort to improve yield. Seed oil content of USDA‐N6006 (237 g kg−1) was similar to that of elevated seed oil cultivar NC‐Dilday, but significantly higher than NC‐Dunphy (228 g kg−1) in the Uniform Trials. Seed protein content and estimated meal protein contents of USDA‐N6006 (389 g kg−1and 46.4%, respectively) were similar to that of NC‐Dunphy. USDA‐N6006 should be excellent parental stock for applied breeding in the southern United States. Increased rainfall events and flooding are becoming more common, which can substantially reduce yield.Flood tolerance in soybean is important for increasing yield potential in high stress environments.High yielding soybean germplasm such as USDA‐N6006, with an increased oil content can be developed through strategic breeding.An increased oil content can be valuable when developing soybeans for the alternative fuel market.

USDA‐N5001 (Reg. no. GP‐524, PI 702592) is a conventional early maturity group (MG) V soybean [Glycine max(L.) Merr.] germplasm with high yield potential and elevated seed and meal protein contents. USDA‐N5001 was jointly released as a non–genetically modified germplasm by the USDA‐ARS and the North Carolina Agricultural Research Service in January 2023. USDA‐N5001, experimental name N16‐590, was derived from the hybridization of high‐yielding breeding line N08‐145 and high‐protein breeding line Pro5‐1. Across 22 environments of the 2019 and 2020 USDA Uniform Soybean Trials Southern States, USDA‐N5001 yielded 105%, 98%, and 102% of the three checks ‘Ellis’, ‘AG55X’, and ‘TN11‐5140’, respectively. On a zero‐moisture basis, its protein content (425 g kg−1) was significantly higher (p< 0.05) than those of the checks (399–402 g kg−1). The meal protein content of USDA‐N5001 (49.4%) was also significantly higher (p< 0.05) than the checks (46.7%–46.9%). The new release matured 2 days and 1 day later than Ellis and AG55X, respectively, but 5 days earlier than TN11‐5140. USDA‐N5001 is the first high‐yielding, high‐seed‐ and meal‐protein MG V‐Early (relative maturity 5.3) line developed by USDA‐ARS in North Carolina. With the recent increases in production of MG V soybeans in the southeastern United States and the national focus on higher‐meal protein lines, USDA‐N5001 should be highly useful to soybean breeders and growers of conventional soybeans in the southeastern United States. Soybean meal and seed protein contents are economically important traits.Soybean seed yield is negatively correlated with seed protein content.Soybean lines with combination of high yield and high protein can be developed with strategic breeding.

USDA‐N7006 is a conventional (non‐genetically modified) maturity group (MG) VII soybean [Glycine max(L.) Merr.] (Reg. no. GP‐525 , PI 702948) germplasm released jointly by the USDA‐ARS and the North Carolina Agricultural Research Service in January of 2023. USDA‐N7006 was released because of its drought tolerance, exotic parentage (37.5%), and high yield potential. USDA‐N7006 traces 12.5% of its parentage to PI 416937 from Japan and 25% to PI 407859‐2 from South Korea. USDA‐N7006 is the first North American soybean release derived from PI 407859‐2. USDA‐N7006 is an F4‐derived germplasm from the hybridization of USDA breeding lines TCPR01‐83 and N01‐11136. From 2015 to 2021, USDA‐N7006 was evaluated in 57 environments across the Southeast in the United Soybean Board (USB) Protein and Diversity MG VII Tests and the USDA Southern Soybean Preliminary and Uniform MG VII Tests. In the MG VII USDA and USB Protein and Diversity Tests, USDA‐N7006 yielded 96% and 98% of the check mean, respectively. Over six droughted environments in North Carolina and South Carolina, USDA‐N7006 exhibited less wilting (greater drought tolerance) than ‘USDA‐N8002’, a previously released cultivar exhibiting drought tolerance. The unique pedigree, delayed canopy wilting under drought stress, and high yield of USDA‐N7006 make it an excellent candidate for parental stock for soybean breeding programs aiming to improve drought tolerance.

The narrow genetic base of the US soybean (Glycine max[L.] Merr.) crop makes it vulnerable to emerging abiotic and biotic stress challenges, and limits resiliency of the soybean crop to meet changes in consumer demand for improved seed composition and agronomic performance. The United States Department of Agriculture Glycine soja(Siebold & Zucc.) germplasm collection provides a valuable genetic resource to meet these challenges. Glycine sojais more genetically diverse than domesticated soybean. Even though wild soybean hybridizes freely with G. max, breeding efforts with wild soybean have not been widely employed because the interspecific progeny inherits undesirable traits from the wild parent. Particularly, these progenies inherit a vine‐like architecture that prevents machine harvest. We assessed the potential for improving recovery of agronomically valuable progeny from interspecific crosses in three experiments using 11 interspecific populations. We found that optimal choice of either parent could triple the frequency of recovery of desirable progeny. Selection for large F3seed size was positively correlated with upright growth habit/plant architecture in five of 11 populations and could triple the recovery of desirable plants. Marker analysis of parents and progeny indicated selection for larger seed size caused minimal selection against the genome of the wild parent. Most genetic markers specific to a wild parent could be recovered in the aggregate of 8–10 upright interspecific progenies, identified via post selection marker analysis. We concluded that choice of parent and selection for larger seed can maximize recovery of the wild genome in machine harvestable progenies. Increasing genetic diversity helps protect soybean yields against climate change and emerging pests.Optimal choice of Glycine maxparent in interspecific crosses increases the utility of Glycine sojaby increasing genetic diversity of the US soybean crop.Selecting larger seed of interspecific populations early in the breeding process enhances the probability of selecting lines with superior agronomic performance.Selection of larger seed size does not have a significant negative impact on recovering the genome of the G. sojaparent in progeny.

Despite being one of the most common injuries around the elbow, the optimal treatment of olecranon fractures is far from established and stimulates debate among both general orthopaedic trauma surgeons and upper limb specialists. It is almost universally accepted that stable non-displaced fractures can be safely treated nonoperatively with minimal specialist input. Internal fixation is recommended for the vast majority of displaced fractures, with a range of techniques and implants to choose from. However, there is concern regarding the complication rates, largely related to symptomatic metalwork resulting in high rates of implant removal. As the number of elderly patients sustaining these injuries increases, we are becoming more aware of the issues associated with fixation in osteoporotic bone and the often fragile soft-tissue envelope in this group. Given this, there is evidence to support an increasing role for nonoperative management in this high-risk demographic group, even in those presenting with displaced and/or multifragmentary fracture patterns. This review summarizes the available literature to date, focusing predominantly on the management techniques and available implants for stable fractures of the olecranon. It also offers some insights into the potential avenues for future research, in the hope of addressing some of the pertinent questions that remain unanswered.Cite this article: Bone Joint J2023;105-B(2):112–123.
