‘Top Shelf’ (Reg. no. CV-380, PI 704478), experimental designation DH162310, is a two-row winter barley (Hordeum vulgare L.) released by Oregon Agricultural Experiment Station in 2023. It is a malting cultivar that is known to be a non-producer of glycosidic nitrile (GN0). GN0 is the precursor to a regulated compound (ethyl carbamate) in distilled spirits and thus, the GN0 trait is becoming a requisite for malting cultivars geared toward distilling. While GN0 spring cultivars have been available for over 20 years, Top Shelf is the first winter GN0 cultivar to be released in North America, and only the second globally. In addition to its GN0 status it exceeds contemporary agronomic and malt quality expectations. Over 5 years of field trials in Oregon it performed equal to or better than the check entries. It shows high yields, plump grains, and test weights. It also has good resistance to scald (caused by Rhynchosporium commune) and preliminary data suggest resistance to barley stripe rust (Puccinia striiformis f. sp. hordei). Results were confirmed in field trials in southern Idaho, a major malting barley production region, and a target environment for this cultivar. Under standard malting protocols Top Shelf meets the guidelines for malt and all-malt and/or grain distilling, and has high extract, enzymatic activity, and free amino nitrogen. When malted under optimized conditions, mimicking commercial distilling malt production, it produced even better results. As one of only a handful of GN0 cultivars available in the United States with potential for mainstream production, Top Shelf provides an important option for the distilling supply chain.

‘FL16045-25’ (Reg. no. CV-1207, PI 704484), a soft red, facultative doubled-haploid wheat (Triticum aestivum L.) cultivar, was developed and tested as FL16045DH-25 by the University of Florida and released in October 2022. FL16045-25 was derived from the cross MD07W478-14-5/GA06112-13EE16. It is well adapted from Texas to Virginia and provides producers with an early-season, facultative (Vrn-A1_short), medium-height, awned, semi-dwarf (Rht2) cultivar that has high yield potential, good straw strength, good grain volume weight, and good end-use quality. It expresses moderate-to-high levels of resistance to most diseases prevalent in the southern United States. Molecular marker analysis confirms the presence of Sbm1, Yr17/Lr37/Sr38, Lr18, Sr36/Pm6, Pm54, and Pm1a-linked disease-resistant genes. The yield average of FL16045-25 from 41 environments during 2020–2022 ranged from 4211 to 5782 kg ha⁻¹, which is competitive with check cultivars that are widely used in the southern part of the United States. The grain volume weight of FL16045-25 ranged from 749 to 785 kg m⁻³ (32 environments), which was higher than most of the checks. FL16045-25 has soft grain texture with softness equivalence varying from 51.3% to 59.3% and sodium carbonate solvent retention capacity (SRC) ranging from 66.8% to 68.5%. Flour yields on a Quadrumat Senior milling system varied from 68.7% to 69.5%. Flour protein content varied from 8.9% to 9.1%. Cookie spread diameter varied from 19.4 to 19.5 cm. The presence of TaSus2-2B, Sucrose Synthase2 gene on 2B or 2G:2B, was confirmed by marker analysis.

‘ND Rodeo’ (PVP no. 202300270; Reg. no. CV-356, PI 703020) is a new slow-darkening (SD) pinto 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. Pinto bean is the largest market class grown in the United States, representing over 47% of the total US production for dry beans, and more than 70% is produced in North Dakota. SD pinto beans offer a good alternative to commercial cultivars of regular darkening (RD) pinto beans, which are typically subject to the risk of economic losses due to seed coat darkening. However, reaching seed yields comparable to RD pintos has been challenging. Between 2017 and 2022, ND Rodeo was tested across 25 environments in North Dakota, where seed yield was significantly higher than the SD pinto cultivars ‘ND Palomino’ and ‘Vibrant’ (18% and 22%, respectively), and comparable with RD pinto cultivars ‘La Paz’ and ‘Monterrey’. ND Rodeo is resistant to Bean common mosaic virus and has intermediate resistance to common bacterial blight, but similar to the commercial checks, it is susceptible to local races/strains of white mold, anthracnose, and rust pathogens. ND Rodeo has an average height of 56 cm which is significantly higher than the average of ND Palomino, Vibrant, and La Paz, and exhibits a desirable upright architecture to facilitate direct harvest. It has a 100-seed weight of 36.2 g and matures in 102 days. Canning quality was rated as acceptable.

‘CP 10-1620’ (Reg. no. CV-216, PI 693837) sugarcane (a complex hybrid of Saccharum spp.) was developed through cooperative research conducted by the USDA–ARS, the University of Florida, and the Florida Sugar Cane League, Inc. At the June 7, 2018, Florida Sugarcane Variety Committee Meeting, CP 10-1620 was released to growers for mineral (sand) soils in Florida, and seed was available in September 2018. CP 10-1620 was selected from a polycross of ‘CP 00-1100’ × ‘CP 05-1740’ (Cross no. X07-1225) made at Canal Point, FL, in December 2007. Neither the female parent, CP 00-1100, nor the male parent, CP 05-1740, is a commercial cultivar. Cane yield of CP 10-1620 on sand soils, averaged across 12 harvests through three crop cycles (plant cane, first ratoon, and second ratoon), was 11.0% higher (P < 0.05) than the combined mean of three checks, ‘CL 88-4730’, ‘CP 96-1252’, and ‘CPCL 97-2730’, which are commercial checks for sand soils. The commercial recoverable sucrose for CP 10-1620 was not significantly lower than the combined mean of the checks but the higher cane yield resulted in 8.4% higher (P < 0.05) sucrose yield than the combined mean of the checks. CP 10-1620 was released because of its high cane yields on sand soils, and its acceptable levels of resistance to brown rust (caused by Puccinia melanocephala H. & P. Sydow), leaf scald (caused by Xanthomonas albilineans Ashby, Dowson), Sugarcane mosaic virus strain E (mosaic), smut (caused by Sporisorium scitamineum), Sugarcane yellow leaf virus, and ratoon stunt [caused by Leifsonia xyli subsp. xyli (Davis et al.) Evtushenko]. CP 10-1620 was moderately susceptible to orange rust (caused by Puccinia kuehnii E. J. Butler), and it has high freeze tolerance. CP 10-1620 tested positive for the Bru1 locus, which is an indicator of brown rust resistance.

‘CP 13-1954’ (Reg. no. CV-218, PI 704104) sugarcane (Saccharum spp. hybrid) was developed through cooperative research conducted by the USDA–ARS, the University of Florida, and the Florida Sugar Cane League, Inc., and released to growers for organic (muck) soils in Florida in June 2020. The parentage of CP 13-1954 is ‘CP 85-1491’ × Poly 09-24. Based on the results of three crops (plant cane, first ratoon, and second ratoon) in field trials conducted at five locations, CP 13-1954 had higher cane yield (16.2%), sucrose yield (15.6%), and economic index (29.7%) at P < .05 compared with the reference cultivar, ‘CP 96-1252’. CP 13-1954 stalks are usually taller than the reference cultivar, ‘CP 00-1101’, with small-to-medium diameter, and exhibits resistance to ratoon stunting disease, Sugarcane mosaic virus strain E, brown rust, orange rust, and smut and moderate resistance to leaf scald on muck soils in Florida. CP 13-1954 has Bru1 locus that provides resistance against brown rust. CP 13-1954 showed moderate cold tolerance among all the tested cultivars.

‘ND Redbarn’ (PVP. no. 202300271; Reg. no. CV-357, PI 703021) is a new dark red kidney bean (Phaseolus vulgaris L.) cultivar developed by the Dry Edible Bean Breeding Program at North Dakota State University and released in 2023 by the North Dakota Agricultural Experiment Station. Compared to other market classes, kidney beans usually command higher prices. However, kidney beans are less productive than other market classes. Minnesota is the largest dark red kidney bean producer in the United States, accounting for ∼90% of the total production in 2022. ND Redbarn was released based on its good adaptation to this region, higher seed yield, large seed size, and desirable seed shape characteristics. Between 2012 and 2021, ND Redbarn was tested across 16 environments in Minnesota, where seed yield was significantly higher than commercial checks ‘Montcalm’, ‘Red Hawk’, and ‘Talon’ (14%, 27%, and 9%, respectively) and comparable with ‘Dynasty’. ND Redbarn is resistant to Bean common mosaic virus and has intermediate resistance to common bacterial blight. ND Redbarn exhibits higher field tolerance to the root rot fungal complex infection compared to Montcalm, Red Hawk, and Talon, and is similar to Dynasty. ND Redbarn has shown higher levels of tolerance to white mold than Montcalm and Red Hawk. Under Minnesota environments, ND Redbarn shows an average plant height of 51 cm, has a 100-seed weight of 50.4 g, and matures in approximately 99 days. The canning quality for Redbarn is within acceptable commercial ranges.

‘TifJumbo’ (Reg. no. CV-157, PI 701814) is a virginia-type peanut (Arachis hypogaea L. subsp. hypogaea var. hypogaea) cultivar released by the USDA–ARS and the Georgia Agricultural Experiment Station in 2021. TifJumbo was developed at the University of Georgia Coastal Plain Experiment Station, Tifton, GA. Our research objective was to develop a high oleic acid, virginia market-type cultivar that also has resistance to the peanut root-knot nematode [Meloidogyne arenaria (Neal) Chitwood race 1] and resistance to spotted wilt caused by Tomato spotted wilt tospovirus (TSWV). Breeding populations were developed by hybridizing C1805-2-9-16 × N08082olJCT. C1805-2-9-16 is a breeding line selected from the cross of Tifguard × ‘Florida-07’. N08082olJCT is a ‘Bailey’-derived, high-oleic breeding line. Marker assisted selection was used in the development of TifJumbo to select for nematode resistance and the high oleic to linoleic (O/L) characteristic. TifJumbo has a high level of resistance to both the peanut root-knot nematode and TSWV and has a high O/L ratio. When tested in fields without nematode pressure, TifJumbo exhibited yields that were at least similar to other currently grown peanut cultivars. When tested in fields with nematode pressure, TifJumbo exhibited significantly higher yields in comparison to Bailey, a widely grown, nematode-susceptible, virginia-type cultivar. Grade variables for TifJumbo were similar to other common virginia-type peanut cultivars. Seed size and size distribution were similar to other virginia-type cultivars.

The complex hybrid sugarcane (Saccharum spp.) cultivar ‘CP 15-1407’ (Reg. no. CV-217; PI 704105) was made available to growers in June 2022 for cultivation on muck soils in Florida. This development took 10 years thanks to collaborative research by the USDA–ARS, the Florida Sugar Cane League Inc., and the University of Florida. It started at Canal Point (CP) as a bi-parental cross between ‘CP 08-1110’ (female) and CP 05-1616 (male). Due to its high stalk weight, adequate disease resistance, higher recoverable sugar, and equivalent cane yield to best check ‘CP 96-1252’ on muck soils, the Florida Sugarcane Variety Committee recommended releasing CP 15-1407. It has demonstrated resistance to brown rust, orange rust, sugarcane mosaic, smut, leaf scald, and ratoon stunt and is moderately susceptible to yellow leaf. In late-stage, on-farm yield trials, CP 15-1407 stalk weights were 27.8% heavier than that of CP 96-1252, while cane yields and economic index (EI) did not differ from CP 96-1252. Florida sugarcane output and crop sustainability are predicted to benefit from CP 15-1407's sustained cane production capacity and proven disease resistance.

‘FL12034-10’ (Reg. no. CV-389, PI 704483), a facultative oat (Avena sativa L.) cultivar, co-developed by the University of Florida and Louisiana State University Agricultural Center, was released in October 2022. FL12034-10 was derived from a three-way cross LA06055SBSBSB-79/FL11048 F₁. It is well adapted across the southern United States and provides producers with a medium-tall, mid-season, awnless, white-glumed, dual-purpose oat that has high yield potential, good straw strength, and good forage yield. FL12034-10 was observed to be uniform and stable across environments in the southern United States from 2017 to present. The line possesses a semi-prostrate growth habit, vigorous growth, and high tillering capacity, and has large leaves that are dark green in color. It expresses moderate-to-high levels of resistance to most oat diseases prevalent in the southern United States. The crown and stem rust and Barley yellow dwarf virus ratings (0–9 scale) of FL12034-10 were 1.7, 0.7, and 1.5, respectively, across different environments. The disease ratings were better than most of the checks. The grain yield average of FL12034-10 from 41 environments during 2018–2021 was 6437 kg ha⁻¹, which is competitive with check cultivars that are widely used in the southern part of the United States. The forage yield of FL12034-10 ranged from 2358 to 6617 kg ha⁻¹ (20 environments), which was higher than most of the checks. FL12034-10 demonstrated better lodging and disease resistance, higher grain yield potential, and higher mid-winter to late spring season forage yield potential than Horizon 720 and Legend 567 oats released by University of Florida.
