‘ND Rosalind’ (Reg. no. CV-364, PI 705585) is a new pink bean (Phaseolus vulgaris L.) cultivar developed by the Dry Edible Bean Breeding Program at North Dakota State University and released by the North Dakota Agricultural Experiment Station. ND Rosalind was developed using a modified pedigree breeding method to the F_4:5 generation followed by pure line selection for disease, agronomic, and quality traits. Between 2017 and 2023, ND Rosalind was tested across more than 11 environments in North Dakota, where seed yield was significantly higher than other pink bean cultivars such as ‘Magnolia’, ‘Rosetta’, and ‘Sedona’ (23%, 12%, and 16% respectively). ND Rosalind is resistant to both the Bean common mosaic virus and Bean common mosaic necrotic virus and has intermediate resistance to common bacterial blight. ND Rosalind has desirable upright architecture (Type IIa). Under North Dakota conditions, ND Rosalind shows an average plant height of 56 cm, has a 100-seed weight of 30.9 g, and matures in ∼101 days. ND Rosalind has a bright seed color and an acceptable canning quality. Other traits of agronomic and economic importance are within acceptable commercial ranges.

Arkot 1301 (Reg. no. GP-1152, PI 706424), Arkot 1308 (Reg. no. GP-1153, PI 706425), Arkot 1309 (Reg. no. GP-1154, PI 706426), Arkot 1311 (Reg. no. GP-1155, PI 706427), and Arkot 1317 (Reg. no. GP-1156, PI 706428) are conventional cotton (Gossypium hirsutum L.) germplasm lines released by the Arkansas Agricultural Experiment Station in November 2024. Arkot 1301 was derived from a cross of Arkot 0111 and Arkot 0222. The other four lines were derived from crossing an Arkot line with a line from another public cotton breeding program. Arkot 1309 and Arkot 1311 lines share MD10-5 as a common parent. The second parent for Arkot 1309 and Arkot 1311 was ‘UA48’ and Arkot 0222, respectively. Arkot 1317 was derived from crossing Arkot 0219 and MD87. Arkot 1308 came from crossing Arkot 0409 with GA2009100, an unreleased breeding line developed by the University of Georgia. Arkot 9111 was in parentage of all lines except Arkot 1309. In replicated field tests at four Arkansas sites over 5 years, the five lines produced equal or more lint yield than UA48 and ‘UA222’. Wide adaptation of the lines was indicated by high lint yields of lines in 2021 regional tests. All four lines displayed high resistance to bacterial blight. Plant (leaf, stem, and bract) trichomes, tarnished plant bug response, and yield component traits varied among the lines but were generally more like UA222 than UA48.

Oil accounts for about 50% of the value of soybean [Glycine max (L.) Merr.]. A changing marketplace demands soybean oil with reduced amounts of linoleic and linolenic acid to increase shelf-life and with increased amount of oleic acid to compete with heart-healthy oils. Meal accounts for the other half of the value of the crop. Higher protein quantity and quality in soybean meal increases its value as animal feed and human food. USDA-N6007HOLL is a conventional, maturity group VI soybean (Reg. no. GP-530, PI 706251) germplasm with white flower, gray pubescence, and brown pod wall jointly released by the USDA Agricultural Research Service and the North Carolina Agricultural Research Service in 2024. USDA-N6007HOLL is a high-yielding germplasm bred by backcrossing four fatty acid desaturase mutant alleles into ‘NC-Roy’. Yield, seed protein content, seed oil content, meal protein content, maturity data, plant height, lodging, and seed size of USDA-N6007HOLL were comparable to NC-Roy. These four fatty acid desaturase alleles result in oil with high-oleic (>80%) and low combined linoleic plus linolenic (<7%) acids. This oil profile meets the need of the world oil market for heart-healthy and shelf-stable oil competing well with olive and canola oil.

‘Colossus LJ’ (Reg. no. CV-563, PI 692622) and ‘Goliath LJ’ (Reg. no. CV-562, PI 692621) soybean [Glycine max (L.) Merr.] cultivars were developed by the Clemson University Pee Dee Research and Extension Center in Florence, SC, and released as forage maturity group (MG) VII and MG VIII glyphosate-tolerant cultivars, respectively. After release, both cultivars were licensed by Specialty Seed Incorporated, a company dedicated to providing premium wildlife food plot seed. Goliath LJ is an F₅-derived single plant selection from a cross between SC98-1850 and SC01-785RR. Colossus LJ is a F₄-derived line originating from a cross combination of SC98-1930 × SC00-892RR. Goliath LJ and Colossus LJ both exhibit the long juvenile trait (LJ), which can extend vegetative growth under short day growing conditions. Colossus LJ and Goliath LJ were evaluated in yield trials as MG VII and MG VIII breeding lines, respectively, over 7 years in 46 environments. When compared to grain and forage type soybean cultivars across three South Carolina environments, 2016–2018, Colossus LJ (3107 kg ha⁻¹) and Goliath LJ (2925 kg ha⁻¹) yielded significantly similar to the grain mean (2983 kg ha⁻¹) and significantly higher than the forage mean (2623 kg ha⁻¹). Plant heights of Colossus LJ (102 cm) and Goliath LJ (107 cm) were significantly higher than the grain mean (78 cm) and significantly similar to the forage mean (109 cm). Forage nutritive value analysis showed crude protein of Colossus LJ and Goliath LJ were significantly higher than the forage and grain mean measured across two growth stages. In addition, both lines exhibited a significantly lower acid detergent fiber and neutral detergent fiber in the leaf and pod. Colossus LJ and Goliath LJ are excellent candidates for forage production because of their high biomass production, increased nutritional value, and adaptation to a wide range of growing conditions.

‘MT Blackbeard’ (Reg. no. CV-1212, PI 703025) and ‘MT Raska’ (Reg. no. CV-1213, PI 703026) are spring durum wheats (Triticum turgidum L. ssp. durum) developed by the Montana Agricultural Experiment Station and released in 2022. MT Blackbeard was bred using a four-parent cross followed by single seed descent and was selected for high yield under rainfed conditions across Montana, low grain cadmium accumulation, large seed size, high gluten strength, and resistance to the most common races of the stem rust (Puccinia graminis f. sp. tritici) and leaf spot pathogens in Montana. MT Raska was also bred using a four-parent cross followed by single seed descent and was selected for high yield under rainfed conditions across Montana, semi-dwarf plant height, exceptional test weight, semolina color retention, and resistance to the most common races of the stem rust and leaf spot pathogens in Montana. Both lines yield well in the North Central and Eastern regions of Montana, where most Montana durum is produced and are intended for pasta production. MT Blackbeard is approximately 72.7 cm tall, similar to the commonly produced line ‘ND Riveland’, has signature black awns, and flowers 1 day later than ND Riveland. MT Raska is approximately 56.2-cm tall, significantly shorter than ND Riveland, and flowers approximately 4 days earlier than ND Riveland.

‘Tepehuán-RS’ (Reg. no. CV-365, PI 706601), tested as line P-SALTILLO×TA-245-1-2-4, is a new drought-tolerant and slow darkening pinto bean cultivar (Phaseolus vulgaris L.). Tepehuán-RS showed high grain yield in low plant densities. It was jointly developed by INIFAP, Postgraduate College and Autonomous University of Chihuahua, released by INIFAP-Sierra of Chihuahua Experimental Station. Bean is one of the most important crops in Mexico by sown area, with 1.4 million ha. The mean bean yield in Mexico is 520 kg·ha⁻¹ in rainfed conditions. Production is considerably affected by two main problems, drought and low densities of sown and harvested plants. This sparse plant cover exposes the soil for a longer period, leading to increased water loss through evaporation and exacerbating drought stress. Tepehuán-RS emerges as the superior variety in all environments studied during 2022 and 2023 with a mean yield of 2125.9 kg·ha⁻¹. While the control Pinto Saltillo showed a yield of 1818.4 kg·ha⁻¹, Tepehuán-RS produced 12.9% more than Pinto Saltillo. When analyzing all environments with drought, in 2022 and 2023, Tepehuán-RS was the best with a yield of 1645.7 kg·ha⁻¹. Under these conditions, Pinto Saltillo presented a yield of 1168.4 kg·ha⁻¹. Interestingly, Tepehuán-RS surpassed the control by a remarkable 41.8%. This variety presents the best grain yield even at low plant densities and field irrigation-drought experiments. Genetic markers and pathogen testing indicate Tepehuán-RS has the I gene for resistance to Bean common mosaic virus, the Co-4² gene for anthracnose resistance, and molecular marker Pvsd-1157 linked to slow darkening gene sd sd of the seed coat.

USDA-ARS-GMD 2427 (Reg. no. GP-1158, PI 706599), USDA-ARS-GMD 2442 (Reg. no. GP-1159, PI 706600), and USDA-ARS-GMD 24141 (Reg. no. GP-1157, PI 706598) are noncommercial breeding lines of cotton (Gossypium hirsutum L.) released by the USDA-ARS at Stoneville, MS, in 2024. Tetraploid hybrids of tri-species, G. arboreum L/G. hirsutum/G. aridum Skovst (AADD) was derived from crosses between G. arboreum (AA) and a hexaploid bridge line, G. hirsutum/G. aridum (AADDDD) followed by three backcrosses to Upland cotton. Lines were selected in F₅ progenies and were evaluated at Stoneville in 2017, 2018, and 2019 and at seven locations across the US Cotton Belt in 2020 in the Regional High Quality test. In all tests, the three lines had significantly higher fiber strength than checks, 5% to 25% higher than the high fiber quality check, MD 15, and 10% to 18% higher than commercial checks. Other fiber properties including fiber length, uniformity, elongation, and micronaire were in acceptable ranges. Yield of the three lines was low to moderate compared with the high-yielding checks. The three lines had significantly different fiber strength and lint yield among themselves. USDA-ARS-GMD 24141 had high fiber strength with yield equivalent to SureGrow 747 and higher than MD 15. This line had intermediate resistance to Fusarium wilt race 4 compared to the susceptible checks and resistant checks. USDA-ARS-GMD 24141 is registered with another two sister lines, USDA-ARS-GMD 2427 and USDA-ARS-GMD 2442. The released germplasm lines can be used by breeders for genetic improvement of fiber strength and by molecular scientists for identification of high fiber strength genes and their genomic locations.

13AFX6 (Reg. no. GP-1151, PI 705849) and 13AFX13 (Reg. no. GP-1150, PI 705848) are noncommercial breeding lines of cotton (Gossypium hirsutum L.) released by the USDA-Agricultural Research Service in 2023. 13AFX6 and 13AFX13 display superb fiber strength and length notably better than high fiber quality cultivars used as checks and perform well across the US Cotton Belt. Both 13AFX6 and 13AFX13 are breeding lines developed from two unique sets of single crosses between upland cotton lines. These initial crosses were followed by individual plant selections in the F₂ and F₃ generations, and progeny row selection in the F₄ generation. The F₄ selections were grown in replicated tests at College Station, TX, and Florence, SC, in 2017 and 2018. The two best unrelated lines from these evaluations were grown in the Regional Breeders Testing Network in 2019. In this trial, 13AFX6 had significantly higher fiber strength and fiber length than other entries in the test. 13AFX13 also had excellent fiber strength and length, significantly higher than the checks used in the trial. Both lines had lint yields equivalent to the DP493 and FM958 checks. The outstanding fiber quality traits and good yields make 13AFX6 and 13AFX13 excellent choices to use as parents to incorporate fiber quality into cotton breeding programs.

‘Georgia-24NHO’ (Reg. no. CV-160, PI 706577) is a new high-yielding, very high-oleic, Tomato spotted wilt virus (TSWV)-resistant, and root-knot nematode (RKN) [Meloidogyne arenaria (Neal) Chitwood]-resistant, large-seeded, runner-type peanut (Arachis hypogaea L. subsp. hypogaea var. hypogaea) cultivar that was released by the Georgia Agricultural Experiment Station in 2024. It was developed at the University of Georgia, Tifton Campus. Georgia-24NHO originated from a cross made between ‘Georgia-06G’ × GA 122704. Georgia-06G is a normal-oleic, TSWV-resistant, large-seeded, runner-type peanut cultivar. GA 122704 is a high-oleic, RKN-resistant, advanced Georgia breeding line. Pedigree selection was practiced within the early segregating generations. Performance testing began in the F_4:6 generation with the advanced pure-line selection, GA 192710. During the past 3 years (2021–2023) averaged over 13 multiple location tests without nematode pressure in Georgia, Georgia-24NHO had significantly less total disease incidence than ‘Georgia-14N’. Georgia-24NHO was also found to have a larger runner seed size as compared to the smaller runner-type check cultivar, Georgia-14N. Georgia-24NHO combines high-yield, TSWV-resistance, and RKN-resistance with large seed size and the very high-oleic trait for longer shelf-life and improved oil quality of peanut and peanut products.

‘Essekerka’ (Reg. no. CV-1211, PI 704099), hard red winter wheat (Triticum aestivum L.) was developed by the Agricultural Institute Osijek (Croatia) and released in 2023. Essekerka was derived from the cross ‘Irishka’ × ‘Apache’. It was tested under experimental number Osk.4.354/12-18 and showed high grain yield with enhanced dough quality in trials (2019–2022) based on farinograph analysis. Essekerka has grain yield comparable to two high-yielding hard red winter wheat check cultivars (Apache and ‘Kraljica’). Essekerka has higher grain yield than hard red winter wheat cultivar ‘Viktorija’ which is declared as check for quality. Overall, better Fusarium head blight resistance was observed in Essekerka than in ‘Vikotrija’. Compared with one of the parent Apache, in various trials Essekerka matured 2–3 days earlier and was 2- to 3-cm shorter.
