‘ND Galaxy’ (Reg. no. CV-367, PI 708328) is a new cultivar belonging to the black bean (Phaseolus vulgaris L.) market class, developed by the dry bean breeding program at North Dakota State University and released by the North Dakota Agricultural Experiment Station. ND Galaxy is a mid- to full-season, high-yielding black bean with commercially acceptable seed size, shape, and appearance. ND Galaxy has desirable upright architecture (Type IIa), facilitating direct harvest. Under North Dakota conditions, ND Galaxy shows an average plant height of 52 cm, has a 100-seed weight of 18.1 g, and matures in ∼97 days. Canning quality and color was rated as acceptable. ND Galaxy has shown an average seed yield increase of approximately 101 and 123 kg ha⁻¹ over ‘Eclipse’ and ‘ND Twilight’, respectively, and 224 kg ha⁻¹ more than ‘Zorro’. However, no significant difference was found when compared to ‘Blacktails’. Since Eclipse and Blacktails are the most commonly grown cultivars in North Dakota, ND Galaxy could be an excellent additional choice for farmers. Besides the high seed yield potential, ND Galaxy has improved resistance to common bacterial blight (CBB) and resistance to Bean common mosaic virus. The CBB intermediate resistance (2.8 ± 0.5) observed in field conditions under natural infection showed that ND Galaxy performed better than most of the black bean cultivars commonly grown in North Dakota; therefore, it could lead to increased economic benefit for farmers and the rest of the bean value chain across the northern Great Plains.

The non-nodulation trait from Harosoy-NN and Williams-NN was introgressed into an elite soybean [(Glycine max (L.) Merr.] cultivar, ‘KS4120NSGT’ (Reg. no. GP-545, PI 708128), through backcrossing to combine non-nodulation with high yield, and desirable agronomic traits. The effort aimed to address the gap in yield between older non-nodulation lines and modern nodulating cultivars. Four non-nodulating near-isogenic lines—KS4120-1_rj1 (Reg. no. GP-533, PI 708116), KS4120-2_rj1 (Reg. no. GP-534, PI 708117), KS4120-3_rj1 (Reg. no. GP-539, PI 708118), and KS4120-4_rj1 (Reg. no. GP-540, PI 708119)—were developed from the Harosoy-NN source, while four nodulating lines—KS4120-5_Rj5/rj6 (Reg. no. GP-542, PI 708121), KS4120-6_Rj5/rj6 (Reg. no. GP-536, PI 708123), KS4120-7-1_Rj5/rj6 (GP-538, PI 708125), and KS4120-7-2_Rj5/rj6 (Reg. no. GP-544, PI 708127)—and four non-nodulating lines—KS4120-5_rj5/6 (Reg. no. GP-541, PI 708120), KS4120-6_rj5/6 (Reg. no. GP-535, PI 708122), KS4120-7-1_rj5/6 (Reg. no. GP-537, PI 708124), and KS4120-7-2_rj5/6 (Reg. no. GP-543, PI 708126)—were developed from heterogeneous BC₄F₂-derived inbred families (HIFs) from Williams-NN source. Molecular marker analysis confirmed the presences of rj1, or rj5 and rj6 in the non-nodulating lines. All lines retained key agronomic traits of the recurrent parent, including purple flowers, tawny pubescence, brown pods at maturity, indeterminate growth habit, yellow seed coats and black hilum. Selection for non-nodulation/nodulation from the elite × non-nodulation donors was made using both phenotypic and marker-assisted selection methods. Field evaluations across Arkansas, Georgia, and Kansas in 2021 and 2022 demonstrated the superior yield potential, agronomic performance, and adaptability of the recurrent parent and derived lines compared to the NN check genotypes, Harosoy-NN and William-NN. When fertilized with N, seed yield, maturity, lodging, plant height, seed weight, and protein and oil concentrations were usually not significantly different between the recurrent parent and the NN lines within environments. The lines are potentially important resources in soybean studies to elucidate biological N fixation and N management in relation to soybean yield and seed composition.

The Oregon Wolfe Barley (OWB) mapping population (Reg. no. MP-4, NSL 554937 MAP) is a resource for genetics research and instruction. The OWBs are a set of doubled haploid barley (Hordeum vulgare L.) lines developed at Oregon State University from the F₁ of a cross between Dr. Robert Wolfe's dominant and recessive marker stocks. Exhibiting a high level of genetic and phenotypic diversity, the OWBs are used throughout the world as a research tool for barley genetics. To date, these endeavors have led to 56 peer-reviewed publications, as well as three reports in the Barley Genetics Newsletter. At the same time, the OWBs are widely used as an instructor resource at the K–12, undergraduate, graduate, and professional levels. They are currently used at universities and/or institutes in German, Italy, Norway, Spain, and the United States and are currently being developed further for educational use in other countries. Genotype and phenotype data, lesson plans, and seed availability information are available herein and online.

Castor (Ricinus communis L.) cultivars are needed with specific adaptation to environmental conditions in Durango and other states of the semi-arid highlands of México. The objective was to develop a castor cultivar adapted to irrigation conditions and favorable rainfall (>500 mm of accumulated rain), to produce high-quality grain and valuable castor-oil for the industry. The cultivar ‘SAB 14’ (SB-1 m-2 m-3 m-4u) was generated by mass selection from the heterogeneous population collected in Santiago Bayacora, Dgo. SAB 14 showed yields ranging from 2.1 to 2.9 t ha⁻¹ and an average oil content of 48%. In Durango 2020, SAB 14, compared to a commercial hybrid (378 cm), showed lower plant height (357 cm) and number of days to flowering (79 vs 90), longer primary raceme length (62 cm vs 38 cm), higher yield (2906 kg ha⁻¹ vs 1312 kg ha⁻¹), and higher 100-seed weight (46.2 g vs 44.1 g). SAB 14 is recommended mainly for irrigated areas of the Valle del Guadiana region in Durango, although it also showed adaptation in Aguascalientes. This castor cultivar represents an option for productive reconversion and reducing seed imports and cost. SAB 14 is currently used in Durango and other states for establishing demonstration plots to evaluate its adaptability, adoption possibilities, and potential to increase the yield and quality of grain, oil, protein cake, and biofuel.

PD 20170034 (Reg. no. GP-1163, PI 708129), PD 20170044 (Reg. no. GP-1164, PI 708130), PD 20170057 (Reg. no. GP-1165, PI 708131), and PD 20170060 (Reg. no. GP-1166, PI 708132) are noncommercial breeding lines of upland cotton (Gossypium hirsutum L.) jointly released by the USDA-ARS and Cotton Incorporated in 2021. PD 20170034, PD 20170044, PD 20170057, and PD 20170060 are breeding lines selected from a cross between an elite cultivar or germplasm line and an exotic landrace accession from Africa, Central America, or South America. Each breeding line possesses 50% exotic landrace parentage and excellent fiber quality significantly better than several commercial cultivars such as ‘Deltapine 393’, ‘Phytogen 72’, and ‘UA 48’. PD 20170034, PD 20170044, PD 20170057, and PD 20170060 display good adaptation in three distinct regions of the US upland cotton production area and provide cultivar development programs valuable sources of new genetic diversity.

Cotton (Gossypium hirsutum L.) germplasm lines BARBREN 713-32-28 (Reg. no. GP-1160, PI 706595), BARBREN 713-32-30 (Reg. no. GP-1161, PI 706596), and BARBREN 713-32-38 (Reg. no. GP-1162, PI 706597) were developed and released by the USDA-ARS in 2024. The objective of the releases was to provide breeders with agronomically elite germplasm that is resistant to both reniform nematode (Rotylenchulus reniformis Linford & Oliveira) and root-knot nematode [Meloidogyne incognita (Kolfoid & White) Chitwood]. The releases also reduce the severity of Fusarium wilt caused by several genotypes of Fusarium oxysporum f. sp. vasinfectum (Fov). The lines have simple sequence repeat (SSR) DNA markers CIR316_202 and BNL3661_185 for the Mi-1 and Mi-2 genes for resistance to root-knot nematode, respectively, and BNL 3279_105 and BNL 569_131 for the Ren₂^GB713 and Ren₃^GB713 genes for resistance to reniform nematode. The single nucleotide polymorphism (SNP) marker GI-187401 also was associated with the Ren₂^GB713 gene. In controlled environment assays, these lines suppressed numbers of reniform nematode eggs by a mean of 83.6% and root-knot nematode eggs by a mean of 97.2% compared to control plants. The released lines with both Mi-1 and Mi-2 genes had significantly greater shoot weight than other experimental lines with the Mi-1 gene alone, but not the Mi-2 gene in soils infested with both root-knot nematode and several genotypes of Fov race 1. The lines outyielded Fibermax ‘FM 966’ by 12% to 20% and had fiber quality equal to or greater than Phytogen ‘PSC 355’.

The USDA-ARS and Utah Division of Wildlife Resources announce the release of bluebunch wheatgrass [Pseudoroegneria spicata (Pursh.) A. Löve.] cultivars ‘USDA-Basin’ (Reg. no. CV-35, PI 708099) and ‘USDA-Wasatch’ (Reg. no. CV-36, PI 708100) (experimental designations: Basin/Basin-STZ4 and Wasatch/Basin-STZ3a, respectively) for their seedling drought tolerance and establishment, and as the first bluebunch wheatgrass cultivars that geographically and genetically originate from the Great Basin region of the United States. Though regionally sourced materials are desired, most bluebunch wheatgrass used for re-seeding this region originate in the Columbia Plateau and Blue Mountains of eastern Washington state. Therefore, bluebunch wheatgrass was collected from the Great Basin and evaluated for relative fitness. Four collections from within each of two phylogeographic groups were selected and crossed to form USDA-Basin and USDA-Wasatch. Genotyping and morphological measurements demonstrated that USDA-Basin and USDA-Wasatch are significantly (P < 0.05) different from each other and four check cultivars. In response to drought, seedling root growth for both was greater (P < 0.05) than ‘Columbia’ and ‘P-7’, but similar to (P > 0.05) ‘Anatone’, whereas they had lesser (P < 0.05) specific leaf area than checks, indicative of enhanced seedling drought tolerance. USDA-Basin and USDA-Wasatch were similar (P > 0.05) to each other and Anatone for stand establishment (mean of 38%), and both had greater (P < 0.05) establishment at two of three sites than Columbia and ‘Goldar’. USDA-Basin and USDA-Wasatch originate from two seed transfer zones that compose 65% of reseeding efforts within the Central Great Basin and thus contribute important regional components to restoration projects in this region.

‘Scab Stryker’ (Reg. no. PI 706594, PI CV-1216) hard red winter (HRW) wheat (Triticum aestivum L.) was developed and released by the Oklahoma State University wheat improvement program in 2024. With the experimental designation OK16103083, Scab Stryker was selected from the backcross ‘Garrison’*3/WesleyFhb1-106. Our objectives herein are to demonstrate its high level of Fusarium head blight (FHB; caused by Fusarium graminearum Schwabe) resistance in HRW wheat in artificially inoculated environments and identify strengths and weaknesses relevant to US Great Plains wheat use. Before release, Scab Stryker was intermittently tested in Oklahoma yield trials for 4 years during the period 2018–2023. It was evaluated during 2020–2023 in Manhattan, KS, in the hard winter wheat FHB nursery of the US Wheat and Barley Scab Initiative. Scab Stryker is intermediate among contemporary HRW cultivars for grain yield and volume weight but has an exceptionally high level of FHB resistance. Scab Stryker is the only HRW cultivar currently deployed for Oklahoma and surrounding areas harboring the resistance gene Fhb1. Scab Stryker has other positive characteristics including a high inclination to circumvent late-winter freeze events, resistance to leaf spotting diseases, high tolerance to acidic soils, and an acceptable wheat protein level. Potential weaknesses of Scab Stryker include susceptibility to Hessian fly (Mayetiola destructor Say), leaf rust (caused by Puccinia triticina Eriks.), and stripe rust (caused by Puccinia striiformis Westend. f. sp. tritici Eriks.), and a bread baking quality profile that may underdeliver for some industry expectations, particularly mixing time.

‘S17-2193’ (Reg. no. CV-565, PI 707954) is a high-yielding late maturity group IV (relative maturity of 4.7), conventional soybean [Glycine max (L.) Merr.] cultivar developed and released in 2022 by the University of Missouri Fisher Delta Research, Extension, and Education Center. S17-2193 was tested in over 88 environments (40 environments for preliminary, advanced, cooperative and uniform tests; and 48 environments for soybean state variety tests) from 2018 to 2021 in 10 states: Alabama, Arkansas, Illinois, Kansas, Kentucky, Louisiana, Mississippi, Missouri, North Carolina, and Tennessee. Results showed that S17-2193 was well adapted across the mid-South United States. This soybean cultivar has overall mean yield of 4336 kg ha⁻¹, being 104% of non Xtend check overall. S17-2193 averaged 226 g kg⁻¹ oil concentration, which was significantly higher than the conventional soybean cultivar ‘Ellis’. In addition to its high yield potential and high oil concentration, S17-2193 is moderately susceptible to soybean cyst nematode (Heterodera glycines Ichinohe) race 2 (HG Type 1.2.5.7), and resistant to race 3 (HG Type 0). It is also moderately resistant to stem canker (caused by Diaporthe phaseolorum var. meridionalis F. A. Fernández), and resistant to charcoal rot (caused by Macrophomina phaseolina Tassi Goid). S17-2193 is a promising maturity group IV cultivar for mid-Southern growers to improve profits by receiving a premium price where conventional soybean is in demand.

Senegalese are consumers of pasta, couscous, and other semolina products, which are obtained from durum wheat [Triticum turgidum L. durum (Desf)] grain imports. The Senegal River farming system offers a short dry winter season (harmattan) that is suitable for the cultivation of heat tolerant durum wheat. Hence, delivering super-early high-yielding and heat tolerant durum cultivars was a major goal in this region. ‘Amina’ (Reg. no. CV-1217, PI 708102), ‘Dioufissa’ (Reg. no. CV-1218, PI 708103), and ‘Haby’ (Reg. no. CV-1219, PI 708104) are durum wheat cultivars released in 2020 for cultivation in Senegal and West Africa after 4 years of multi-locations testing. All three are elite lines field-selected at the research farms of Fanaye in Senegal and Kaedi in Mauritania, both of which are located along the Senegal River. These cultivars are released jointly by the Senegalese Institute for Agricultural Research (ISRA), National Center for the Agricultural Research and development (CNRADA) in Mauritania, and the International Center for the Agricultural Research in the Dry Areas (ICARDA) in Morocco because of their adaptation to hot irrigated conditions, early maturity, higher grain yield and good grain quality.
