In 2016, it was evaluated in the uniform regional rice nursery trial across four southern states. From 2017 to 2022, CLL17 was evaluated in 50 replicated trials across 10 locations in Louisiana.

The germplasm line represents an ongoing effort to develop improved genotypes with enhanced yield, yield components, seed traits, earliness, host plant resistance, and fiber properties. Arkot 1102ne was compared to ‘UA48’ and ‘UA222’ over 5 years and four test sites in Arkansas. Across all the test sites, lint yields of Arkot 1102ne were 7.9% and 20.8% higher than those of UA222 and UA48, respectively, due to its higher lint percentage, seed per area, and fiber density. Arkot 1102ne produced the highest average yield of 21 genotypes over 10 locations in the 2019 Regional Breeders’ Network Test (RBTN). Arkot 1102ne produced the highest oil and protein percentages at four 2019 RBTN locations where seed were evaluated. Host plant resistance traits that have been measured on Arkot 1102ne include bacterial blight resistance and Verticillium wilt tolerance. Leaf pubescence and bract trichome density of Arkot 1102ne were intermediate between UA48 and UA222, but stem pubescence was lower. This combination of host plant resistance and yield components should lead to more stable yield production over contrasting environments.

Conversely, selection for high yield potential was conducted in non-stress trials with tillage, irrigations, and fertilizers applied for optimal production. USDA Diamondback exhibits wide adaption to production regions across the United States, as evidenced by an average seed yield of 3808 kg ha−1 across 14 location-years in the Cooperative Dry Bean Nursery. Virus testing and resistance gene–linked markers indicate USDA Diamondback has a three-gene combination (bc-ud, bc-1, and bc-3) that confers durable resistance to all known strains of Bean common mosaic virus and Bean common mosaic necrosis virus.

R. Wilczek] is an agro-economically important legume crop of Thailand. In recent years, mungbean has been gaining attention and popularity from consumers and industries for its dense nutrients. Although farmers, consumers, and processors prefer large-seeded mungbeans, all mungbean cultivars available in Thailand are medium-seeded. Therefore, a need was felt to develop new mungbean cultivars with large seed size that would fulfill the needs of farmers, consumers, and processors. In this study, we report the development of two new mungbean cultivars: ‘KUML4’ (Reg. no. CV-354, PI 703288) and ‘KUML8’ (Reg. no. CV-355, PI 703289). These cultivars were developed by pedigree and bulk-selection methods. Standard yield trials revealed that KUML4 gave seed yields (SDY) of 1444.75 and 1316.38 kg ha−1, respectively, which was on par with check cultivars. The seed of KUML4 and KUML8 was larger than all of the check cultivars; their 100-seed weights were 7.25 and 7.84 g, respectively, compared with 6.58 g, the mean of the check cultivars. Further, the genotype main effect plus genotype-by-environment analysis showed that KUML4 had good yield stability for its SDY. The yield trials under farmer fields and practices revealed that KUML4 gave SDY similar to the best check cultivar, ‘Chai Nat 3’ (CN3), whereas KUML8 gave a lower yield than CN3. The yield gap between the experimental research station and farmer field/practice was about 47%. In conclusion, KUML4 and KUML8 have shown high yield, large seed size, and early and uniform maturity.","PeriodicalId":16822,"journal":{"name":"Journal of Plant Registrations","volume":"18 1","pages":"33-41"},"PeriodicalIF":0.8,"publicationDate":"2024-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139397430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These two populations were developed by the USDA-ARS in Fort Collins, CO, derived from unreleased USDA-ARS Salinas germplasm lines 7927-4-308 and 7927-4-309. Multiple field and greenhouse trials for FY and nematode resistance confirmed the homogeneous phenotypic responses of both lines for each disease. To enable molecular breeders to rapidly screen proprietary markers in silico on these lines, gene space assemblies for individual plants from each line were also developed and are being released alongside these genetic stocks. Genome sequencing of individual plants from each line, as well as pooled sequencing of sub-populations of both lines, indicated fixation of a previously reported genetic variant linked to SBCN resistance in FC308. However, two previously reported variants linked to Fusarium resistance appear to be unlinked to the resistance found in FC309. Collectively, these two new sugar beet genetic stock lines should prove useful as sources of resistance to FY and SBCN, as model genetic backgrounds for studying plant–pathogen interactions, and for mapping the causal resistance genes present in these lines.","PeriodicalId":16822,"journal":{"name":"Journal of Plant Registrations","volume":"18 1","pages":"187-196"},"PeriodicalIF":0.8,"publicationDate":"2024-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/plr2.20345","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139397361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 30 families were developed from 27 founder parents—three of the founder parents were backcrossed to both recurrent parents to provide a genetic relationship across all 30 families. Each family consists of 45–100 BC1F4 lines selected for standard agronomic fitness, and each population was genotyped using genotype-by-sequencing.
