The Inland Pacific Northwest is the largest Kentucky bluegrass (Poa pratensis L.) seed production area worldwide. Historically, farmers in Washington burnt Kentucky bluegrass residues, a common practice for pathogen control, pest management and maximum economic revenue. Washington State implements air quality and fire safety burn bans under certain conditions to protect public health and safety. Outside of Native American reservations, burning of Kentucky bluegrass has been outlawed in Washington state, which raised the need for breeding a new Kentucky bluegrass cultivar that will have good yield without burning. ‘Matchless’ (Reg. no. CV-102, PI 701401, PVP 202200523) Kentucky bluegrass is a common-type cultivar released in 2023. Matchless was selected for its superior yield without burning crop residues, derived from the common-type cultivar ‘Kenblue’, in an open-pollinated nursery in Pullman, WA. Matchless was compared to Kenblue, ‘America’, ‘Baron’, and other standard cultivars, and exhibited taller plant height, longer leaf sheath length, and longer panicle length, among other traits. Matchless outperformed Kenblue in turf quality and exhibited similar spring green-up. The combination of statistically significant differences in traits makes Matchless a unique cultivar. It is distinct from its parental cultivar Kenblue and other common-type cultivars and performs and adapts well for use in home lawns, parks, and reclamation projects.

内陆太平洋西北部是世界上最大的肯塔基蓝草(Poa pratensis L.)种子生产区。从历史上看,华盛顿州的农民焚烧肯塔基蓝草的残留物,这是一种常见的做法,用于控制病原体、害虫管理和最大限度地提高经济收入。华盛顿州在某些条件下实施空气质量和消防安全燃烧禁令,以保护公众健康和安全。在美国原住民保留区之外,燃烧肯塔基蓝草在华盛顿州已经被禁止,这就提高了培育一种新的肯塔基蓝草品种的需求,这种品种可以在不燃烧的情况下获得良好的产量。“无与伦比”(Reg。否。CV-102, PI 701401, PVP 202200523)肯塔基蓝草是2023年发布的普通类型品种。在普尔曼的一个开放授粉的苗圃中,Matchless因其优异的产量而被选中,而无需燃烧作物残留物,源自普通类型的栽培品种“Kenblue”。与“肯蓝”、“美洲”、“巴伦”等标准品种相比,“无双”表现出更高的株高、更长的叶鞘长度和更长的穗长等性状。无双在草皮质量上优于垦蓝,并表现出类似的春季绿化。统计上显著的性状差异的组合使无双成为一个独特的品种。它不同于它的亲本品种肯蓝和其他普通类型的品种,表现和适应良好的使用在家庭草坪,公园和填海工程。

Soft red winter wheat (Triticum aestivum L.; SRWW) is a major crop in the US southeast (SE) region. However, growing successful wheat crop is challenged by many stresses resulting in substantial losses in yield and quality. To alleviate these challenges, developing new cultivars with high yield potential with resistance to major pests in the region and good quality is warranted. This constitutes the major goal of the SRWW breeding programs ate the University of Georgia (UGA) and the regional institutions including the southern universities GRAINS (SUNGRAINS) programs. ‘GA09436-16LE12’ (Reg. no. CV-1209, PI 700011) SRWW cultivar was among the adapted wheat developed and released by the UGA College of Agricultural and Environmental Sciences in 2019. While GA09436-16LE12 is generally adapted to the US SE region, it specifically well fit to the Georgia environments. It has high yield, very good resistance to most dominant diseases including leaf (caused by Puccinia triticina Erikss.) and stripe (caused by P. striiformis Westend.) rusts; powdery mildew (caused by Erisyphe graminis); and Soil-borne wheat mosaic virus. GA09436-16LE12 has improved Fusarium head blight (caused by Fusarium graminearum Schwabe) which is reflected in lower levels of Deoxynivalenol toxin and Fusarium damaged kernels levels. It also showed moderate field resistance to Hessian fly [Mayetiola destructor (Say)] although it is susceptible to the biotypes B, C, O, and L. GA09436-16LE12 has good grain volume weight and good milling and baking quality as a SRWW.

软红冬小麦(Triticum aestivum L.;SRWW是美国东南(SE)地区的主要作物。然而,种植成功的小麦作物受到许多压力的挑战,导致产量和质量的重大损失。为了缓解这些挑战,必须开发具有高产潜力、对该地区主要害虫具有抗性且品质优良的新品种。这构成了佐治亚大学(UGA)和包括南方大学谷物(SUNGRAINS)计划在内的区域机构的SRWW育种计划的主要目标。“GA09436-16LE12”(Reg。否。CV-1209, PI 700011) SRWW品种是UGA农业与环境科学学院于2019年开发和发布的适应性小麦之一。虽然GA09436-16LE12一般适用于美国东南地区,但它特别适合乔治亚州的环境。它产量高,对大多数优势病害具有很好的抗性,包括叶片锈病(由小麦锈病引起)和条纹锈病(由条纹锈病引起);白粉病(由禾粉菌引起);以及土壤传播的小麦花叶病毒。GA09436-16LE12改善了镰刀菌头疫病(由禾谷镰刀菌引起),这反映在较低的脱氧雪腐镰刀菌毒素水平和镰刀菌受损的籽粒水平。GA09436-16LE12在田间对黑森蝇(Mayetiola destructor, Say)也表现出中等的抗性,尽管它对B、C、O和l生物型敏感。GA09436-16LE12作为SRWW具有良好的籽粒体积重和良好的碾磨和烘烤品质。

In Utah, spring feed barley (Hordeum vulgare L.) is commonly used in rotation with hay to supply the state's animal products industry. The objective of this research was to develop a spring feed barley cultivar with improved agronomic performance and adaptation to Utah's growing conditions. ‘Rulon’ (Reg. No. CV-382, PI 705157, PVP no. 202400311) is a six-row, spring feed barley cultivar developed and evaluated as UTSB10905-72 and released in 2023 by the Utah Agricultural Experiment Station (UAES). Rulon was derived from the cross UTSB2120-36/‘Goldeneye’. Goldeneye is a six-row spring feed barley cultivar released by UAES in 2005. UTSB2120-36 was an F4-derived experimental line from the cross ‘Century’/‘IdaGold II’. Rulon was selected through a modified bulk breeding scheme from the F2 to the F4 generations. Derived from the F4 generation, Rulon was tested in replicated yield trials in Logan, UT, from 2013 to 2020, the University of Idaho (UI) Extension Variety Trials in 2016 and 2017, and the Western Regional Spring Barley Nursery from 2016 to 2018. Rulon yielded an average of 5987 kg ha−1 in Logan, outperforming all check varieties, and showed similar days to heading compared to Goldeneye. In the UI Extension Variety Trials, Rulon showed higher kernel plumpness (95%) compared to the check varieties (76–88%). In the Western Regional Spring Barley Nurseries, Rulon ranked among the top five yielding entries in 15 out of 25 site-years. Rulon was released on the basis of its high grain yield, excellent kernel plumpness, and high test weight.

在犹他州,春季饲料大麦(Hordeum vulgare L.)通常与干草轮作,以供应该州的动物产品工业。本研究的目的是开发一种具有改良农艺性能和适应犹他州生长条件的春季饲料大麦品种。“Rulon”(Reg。否。CV-382, PI 705157, PVP号。202400311)是由犹他州农业试验站(UAES)于2023年发布的六行春季饲料大麦品种,开发并评价为UTSB10905-72。Rulon源自杂交UTSB2120-36/ ' Goldeneye '。金眼大麦是美国农业部于2005年推出的六行春季饲料大麦品种。UTSB2120-36是从杂交‘Century’/‘IdaGold II’衍生的f4实验系。从F2代到F4代,采用改良的群体育种方案选育Rulon。作为F4代的衍生品种,Rulon于2013年至2020年在犹他州洛根进行了重复产量试验,2016年和2017年在爱达荷大学(UI)进行了推广品种试验,2016年至2018年在西部地区春大麦苗圃进行了重复产量试验。在Logan, Rulon的平均产量为5987 kg ha - 1,优于所有对照品种,抽穗天数与Goldeneye相似。在水稻推广品种试验中,Rulon的籽粒饱满度(95%)高于对照品种(76% ~ 88%)。在西部地区春大麦苗圃中,Rulon在25个站点年中有15个产量排名前五。Rulon因其籽粒产量高、籽粒饱满度好、试重高而被释放。

Four durum wheat (Triticum turgidum ssp. durum) lines Rusty-KLB (Reg. no. GP-1098, PI 705448), Rusty-14803 (Reg. no. GP-1097, PI 705447), Rusty-ST464C1 (Reg. no. GP-1099, PI 705449), and CAT-A1 (Reg. no. GP-1096, PI 705446), which carry stem rust resistance gene Sr13 alleles Sr13a, Sr13b, Sr13c, and Sr13d, respectively, are released by USDA-ARS. These alleles originated from cultivated emmer wheat (T. turgidum ssp. dicoccum) landrace Khapli (CItr 4013), T. turgidum ssp. polonicum accession CItr 14803, durum landrace ST464 (PI 191365), and durum line Camadi Abdu tipo #103 (PI 192168), respectively. Rusty-KLB, Rusty-14803, and Rusty-ST464C1 are near-isogenic lines with the pedigrees Rusty*7/KL-B, Rusty*4/3/Rusty/CItr 14803//2*Rusty, and Rusty*7/ST464-C1, respectively. KL-B, ST464-C1, and CAT-A1 are monogenic lines with the pedigrees Marruecos 9623//Khapli/Marruecos 9623, Marruecos 9623*2/ST464, and Marruecos 9623*2/Camadi Abdu tipo #103, respectively. Sr13 can be detected by perfect markers including Kompetitive allele specific polymerase chain reaction (KASP) marker KASPSr13 and semi-thermal asymmetric reverse polymerase chain reaction (STARP) markers rwgsnp37. Specific alleles can be identified via STARP markers rwgsnp38, rwgsnp39, and rwgsnp40. The Sr13 alleles provide a moderate level of resistance, typically an infection type 2, to a broad spectrum of stem rust races. Sr13c was effective against all 15 stem rust races tested while Sr13a was ineffective only against race TCMJC. Sr13b was ineffective against JRCQC, QCCJC, QFCSC, and TTRTF. Sr13d is notable in being the only Sr13 allele ineffective to TTKSK (Ug99) and TKTTF. These lines are useful for studying the host-stem rust pathogen interactions, identifying new genes, and breeding durum and bread wheat cultivars with stem rust resistance.

四粒硬粒小麦(Triticum turgidum ssp.)Rusty-KLB (Reg.;否。GP-1098, PI 705448), Rusty-14803 (Reg;否。GP-1097, PI 705447), Rusty-ST464C1 (Reg;否。GP-1099, PI 705449), CAT-A1 (Reg;否。GP-1096、PI 705446)分别携带茎锈病抗性基因Sr13等位基因Sr13a、Sr13b、Sr13c和Sr13d。这些等位基因来源于栽培小麦(T. turgidum ssp)。土生植物卡普力(CItr 4013);分别为polonicum accession CItr 14803、durum landrace ST464 (PI 191365)和durum line Camadi Abdu tipo #103 (PI 192168)。Rusty- klb、Rusty-14803和Rusty- st464c1是近等基因系,谱系分别为Rusty*7/KL-B、Rusty*4/3/Rusty/CItr 14803//2*Rusty和Rusty*7/ST464-C1。KL-B、ST464- c1和CAT-A1分别为单基因系Marruecos 9623//Khapli/Marruecos 9623、Marruecos 9623*2/ST464和Marruecos 9623*2/Camadi Abdu tipo #103。Sr13可以通过竞争性等位基因特异性聚合酶链反应(KASP)标记KASPSr13和半热不对称反向聚合酶链反应(STARP)标记rwgsnp37进行检测。特异等位基因可以通过STARP标记rwgsnp38、rwgsnp39和rwgsnp40进行鉴定。Sr13等位基因对广泛的茎锈病品种具有中等水平的抗性,通常为2型感染。Sr13c对15个茎锈病小种均有效,而Sr13a仅对TCMJC小种无效。Sr13b对JRCQC、QCCJC、QFCSC和tttf无效。Sr13d是Sr13中唯一对TTKSK (Ug99)和TKTTF无效的等位基因。这些品系可用于研究主-茎锈病病原相互作用、鉴定新基因、选育具有茎锈病抗性的硬粒小麦和面包小麦品种。

‘MN-Rothsay’ (Reg. No. CV-1208, PI 702731) hard red spring wheat (Triticum aestivum) was released by the University of Minnesota Agricultural Experiment Station in 2022 because of its high grain yield and lodging resistance. MN-Rothsay is a medium-late maturity cultivar with below average plant height, containing the semi-dwarfing alleles Rht-B1b and Rht24b. The lodging resistance of MN-Rothsay is similar to ‘Linkert’, a 2013 release that was the most widely grown cultivar in Minnesota from 2016 to 2020, largely due to its superior lodging resistance.

Plant biologists have long been fascinated with the abnormal, the monstrous, and the defective. Six sib winter wheat (Triticum aestivum L.) lines with varying types of albinism, ShunMai GAG-1 (Reg. no. GP-1090, PI 704106), ShunMai GAG-2 (Reg. no. GP-1091, PI 704107), ShunMai GAG-3 (Reg. no. GP-1092, PI 704108), ShunMai GAG-4 (Reg. no. GP-1093, PI 704109), ShunMai GAG-5 (Reg. no. GP-1094, PI 704110), and ShunMai GAG-6, (Reg. no. GP-1095, PI 704111), were derived from a cross made in 2013 with unknown pedigree, and were developed using conventional phenotypic selections. Albinism, or stage-specific albino, is their unique abnormal agronomic characteristics. All their leaves and tillers produced before winter are green, all their spring-emerging leaves and tillers are albino, and all their summer-producing leaves turn green again. Their main stems could have at least three albino leaves. In some colder springs, their after-winter emerging leaves are reddish to pinkish. They may serve as useful experimental materials for addressing a wide range of wheat breeding problems, and for wheat field art too, and may also be important materials for functional studies and eventually lead to the gene discovery. We discuss the possible interactions between plastid genes and nuclear genes and between vernalization genes responsible for the transition from vegetative to generative growth stage and photosynthetic genes.

长期以来,植物生物学家一直对异常、畸形和有缺陷的植物着迷。六个具有不同类型白化病的同胞冬小麦(Triticum aestivum L.)品系:ShunMai GAG-1(登记号:GP-1090,PI 704106)、ShunMai GAG-2(登记号:GP-1091,PI 704107)、ShunMai GAG-3(登记号:GP-1092,PI 704108)、ShunMai GAG-4(登记号:GP-1093,PI 704109)、ShunMai GAG-5(登记号:GP-1093,PI 704108)、ShunMai GAG-6(登记号:GP-1093,PI 704109)、ShunMai GAG-7(登记号:GP-1093,PI 704108)。GP-1093,PI 704109)、ShunMai GAG-5(登记号:GP-1094,PI 704110)和 ShunMai GAG-6(登记号:GP-1095,PI 704111)均来自 2013 年的一个血统不明的杂交品种,并采用传统的表型选择方法培育而成。白化病或阶段性白化病是其独特的异常农艺特征。它们冬前产生的所有叶片和分蘖都是绿色的,春季萌发的所有叶片和分蘖都是白化的,夏季产生的所有叶片又都变绿。它们的主茎至少有三片白化叶。在一些寒冷的春季,它们冬后萌发的叶子呈红色至粉红色。它们可能是解决各种小麦育种问题的有用实验材料,也可能是小麦田间艺术的有用实验材料,还可能是功能研究的重要材料,并最终导致基因的发现。我们讨论了质体基因与核基因之间可能存在的相互作用,以及负责从无性生长阶段过渡到生成生长阶段的春化基因与光合作用基因之间可能存在的相互作用。

Texas is expected to experience higher night and day temperatures and more extreme and erratic rainfall in the future. Along with the impacts of climate change, the majority of current cotton (Gossypium hirsutum L.) hectarage is expected to have less irrigation water available as the Ogallala aquafer continues to decline. Both of these realities suggest that many of Texas’ cotton producers will return to dryland production which will require reducing input cost, for example, using genetically modified cultivars. Currently, conventional cotton planting seed are about 25% lower in cost per hectare than genetically modified cultivars. Currently, most cultivars offered for sale to Texas producers are transgenic with few conventional cultivars available. The public breeding programs of Texas A&M AgriLife Research develop germplasm with improved traits for private industry and conventional cultivars with yield potential for Texas environments, both irrigated and dryland. ‘Tamcot H12’ (Reg. no. CV-148, PI 705604) was derived from a complex pedigree involving ‘DP 491’ (PI 618609), TAM 96WD-18, TAM 91C-95Ls, and ‘DP Acala 90’ (PVP 8100143). Tamcot H12 performed as well or better than most current cultivars in trials in Texas and across the US Cotton Belt. Tamcot H12 will provide producers with another conventional cotton variety.

预计未来得克萨斯州的昼夜气温将升高,降雨量将更加极端和不稳定。除了气候变化的影响,随着奥加拉拉含水层的不断减少,预计目前大部分棉花(Gossypium hirsutum L. )种植面积的灌溉用水也将减少。这两个现实都表明,得克萨斯州的许多棉花生产者将回归旱地生产,这就需要降低投入成本,例如使用转基因栽培品种。目前,传统棉花种植种子的每公顷成本比转基因栽培品种低 25%。目前,向得克萨斯州生产者出售的大多数栽培品种都是转基因品种,很少有传统栽培品种。得克萨斯州农业生命研究所(Texas A&M AgriLife Research)的公共育种项目为私营企业开发具有改良性状的种质,并为得克萨斯州的灌溉和旱地环境开发具有增产潜力的常规栽培品种。Tamcot H12"(登记号 CV-148,PI 705604)来自一个复杂的血统,其中包括 "DP 491"(PI 618609)、TAM 96WD-18、TAM 91C-95Ls 和 "DP Acala 90"(PVP 8100143)。在得克萨斯州和整个美国棉花带的试验中,Tamcot H12 的表现与当前大多数栽培品种一样好,甚至更好。Tamcot H12 将为生产者提供另一个常规棉花品种。

CA 4011 (Reg. no. GP-1149, PI 705597) is a noncommercial breeding line of cotton (Gossypium hirsutum L.) jointly released by Texas A&M AgriLife Research and the Agricultural Experiment Station at the University of Georgia-Tifton. This cotton germplasm is a selection from CA 3084, a germplasm line released by Texas Agricultural Experiment Station in 1987. CA 3084 was derived from a cross of EPSM-75-AAAA-3 and EPSM-1224-1-74-2-4-2-1, historical breeding lines developed by the cotton breeding program at Texas Agricultural Experiment Station in El Paso. Progeny row of CA 4011 was selected for 2008 preliminary yield testing in Southern High Plains by the Texas A&M AgriLife Research cotton breeding program in Lubbock. In 2012, CA 4011 had less damage from thrips feeding injury than 22 other genotypes tested in a greenhouse assay but was equal to the resistant check TX110 (PI 163608). Performance testing for yield, fiber quality, and other related agronomic properties was conducted under organic management and on certified organic farms during 2012, 2013, and 2014 growing seasons. CA 4011 showed comparable yield and fiber quality to standard check cultivars grown in the Southern High Plains. Subsequent testing was done at the University of Georgia Coastal Plains Experiment Station in Tifton, GA, to evaluate for resistance to the foliar diseases areolate mildew and target spot. Disease ratings were taken in 2018 and 2019 growing seasons. CA 4011 showed favorable resistance to areolate mildew in comparison to susceptible checks, providing less leaf infection and defoliation.

CA 4011(登记号:GP-1149,PI 705597)是德克萨斯州农业生命研究中心(Texas A&M AgriLife Research)和佐治亚大学蒂夫顿分校农业试验站(University of Georgia-Tifton)联合发布的棉花(Gossypium hirsutum L.)非商业育种品系。该棉花种质是从 CA 3084 中选育出来的,CA 3084 是德克萨斯农业试验站于 1987 年发布的一个种质品系。CA 3084 是由 EPSM-75-AAAA-3 和 EPSM-1224-1-74-2-4-2-1 杂交而来,EPSM-75-AAAA-3 和 EPSM-1224-1-74-2-4-2-1 是埃尔帕索德州农业试验站棉花育种项目开发的历史育种品系。CA 4011 的后代于 2008 年由位于卢伯克的德克萨斯 A&M 农业生命研究所棉花育种项目在南部高原进行初步产量测试。2012 年,在温室试验中,CA 4011 受蓟马食害的程度低于其他 22 个基因型,但与抗性对照 TX110(PI 163608)相当。2012 年、2013 年和 2014 年生长季节,在有机管理和认证有机农场进行了产量、纤维质量和其他相关农艺特性的性能测试。CA 4011 的产量和纤维质量与在南部高原种植的标准对照栽培品种相当。随后在佐治亚州蒂夫顿的佐治亚大学沿海平原试验站进行了测试,以评估其对叶面病害赤霉病和靶斑病的抗性。病害评级是在 2018 年和 2019 年生长季节进行的。与易感对照相比,CA 4011 对赤霉病表现出良好的抗性,叶片感染和落叶较少。

Vitamin A deficiency and its associated disorders are pervasive in sub-Saharan Africa (SSA) including many middle- and low-income countries across the world. Provitamin A-enriched maize (Zea mays L.) inbred lines with desirable agronomic and adaptive traits have been developed and used to generate and commercialize maize varieties with medium to high levels of provitamin A in a few countries to curb vitamin A deficiency. Nonetheless, these inbred lines have not been made widely available to the public and private sector breeders in many countries. The main purpose for releasing the 21 provitamin A-enriched tropical maize inbred lines (PI 705424–PI 705444, Reg. nos. GP-624–GP-644) is to supply maize breeders with elite source germplasm for increasing provitamin A and other carotenoids to much higher levels to offset losses during storage, natural degradation, and processing. These inbred lines were developed at the International Institute of Tropical Agriculture (IITA) from backcrosses of high β-carotene temperate lines as donors and elite tropical lines as recipients. These inbred lines were developed through repeated self-pollination with rigorous visual selection among and within lines for plant vigor, synchronous silk emergence and pollen shedding, low ear placement, and resistance to lodging and major tropical diseases, followed by selection for bright yellow to orange kernel color with semi flint to flint kernel texture after harvest. The released maize inbred lines will be diverse sources of favorable alleles to accelerate genetic gain in provitamin A and other beneficial carotenoid enrichment for human health.

维生素 A 缺乏症及其相关疾病在撒哈拉以南非洲(SSA),包括全球许多中等收入和低收入国家普遍存在。富含维生素 A 的玉米(Zea mays L.)近交系具有理想的农艺性状和适应性状,一些国家已开发出富含维生素 A 的玉米品种,并将其商业化,以遏制维生素 A 缺乏症。尽管如此,这些近交系并未广泛提供给许多国家的公共和私营部门育种者。发布 21 个富含维生素 A 的热带玉米近交系(PI 705424-PI 705444,登记号:GP-624-GP-644)的主要目的是为玉米育种者提供精英种质资源,将维生素 A 和其他类胡萝卜素提高到更高水平,以抵消储存、自然降解和加工过程中的损失。这些近交系是国际热带农业研究所(IITA)以高β-胡萝卜素的温带品系为供体、热带精英品系为受体,通过回交培育而成的。这些近交系是通过反复自花授粉培育出来的,并在品系间和品系内对植株活力、同步出丝和花粉脱落、低穗位、抗倒伏和主要热带病害进行了严格的目测选育,随后又对收获后籽粒颜色为亮黄色至橙色、籽粒质地为半燧石至燧石进行了选育。发布的玉米近交系将成为多种有利等位基因的来源,以加速维生素 A 和其他有益于人类健康的类胡萝卜素的遗传增益。

‘Black Pearl’ black bean (Phaseolus vulgaris L.) (Reg. no. CV-362, PI 705445), developed by Michigan State University AgBioResearch, was released in 2023 as an upright, full-season cultivar with anthracnose resistance and superior canning quality. Black Pearl was developed using pedigree breeding method to the F4 generation followed by pure line selection for disease, agronomic, and quality traits. In 5 years of field trials, Black Pearl yielded 3372 kg ha−1, flowered in 47 days, and matured in 98 days on average. Plants averaged 46 cm in height, with lodging resistance score of 1.8 and seed weight of 21.9 g 100 seed−1. Black Pearl combines high yield potential with upright architecture and full-season maturity in a black seed type. Black Pearl has resistance to lodging and high pod placement within the plant making it suitable for direct harvest under narrow row production systems. Black Pearl is resistant to races 7 and 73 of anthracnose, resistant to Bean common mosaic virus, and has shown better resistance to Rhizoctonia root rot than other black bean cultivars. Black Pearl produces seed that meets industry standards for export and packaging and was rated the highest in canned bean color in the black bean market class.

黑珍珠 "黑豆(Phaseolus vulgaris L.)(登记号:CV-362,PI 705445)由密歇根州立大学农业生物研究中心开发,于 2023 年发布,是一种直立型全季栽培品种,具有抗炭疽病和优异的罐头品质。黑珍珠是采用纯系育种法培育到 F4 代,然后进行病害、农艺和品质性状的纯系选育。在 5 年的田间试验中,黑珍珠的产量为每公顷 3372 千克,平均 47 天开花,98 天成熟。植株平均高度为 46 厘米,抗倒伏性为 1.8 分,种子重量为 21.9 克 100 粒-1。黑珍珠结合了高产潜力、直立结构和全季成熟的黑色种子类型。黑珍珠抗倒伏,豆荚在植株内的位置高,适合在窄行生产系统中直接收获。与其他黑豆品种相比,黑珍珠对炭疽病第 7 和第 73 种有抗性,对豆类常见花叶病毒有抗性,对根腐病有更好的抗性。黑珍珠生产的种子符合出口和包装的行业标准,在黑豆市场等级中被评为罐头豆色泽最高的品种。

CV-362, PI 705445), developed by Michigan State University AgBioResearch, was released in 2023 as an upright, full-season cultivar with anthracnose resistance and superior canning quality. Black Pearl was developed using pedigree breeding method to the F<sub>4</sub> generation followed by pure line selection for disease, agronomic, and quality traits. In 5 years of field trials, Black Pearl yielded 3372 kg ha<sup>−1</sup>, flowered in 47 days, and matured in 98 days on average.
