Non Technical Summary
This project will establish a nationwide coordinated transdisciplinary research approach to develop and implement marker assisted selection (MAS) capacity in Vaccinium breeding programs, to enable breeders to select and pyramid fruit characteristics (FCs) that positively contribute to fruit quality and market value. Vaccinium crops (blueberry and cranberry) provides vital contributions to human health and well-being, and collectively constitutes the economic backbone of many U.S. rural communities. Vaccinium genetic and genomic resources are developing rapidly but have not been translated to routine practical application. Specific objectives are to: (1) establish a cost effective genotyping platform to expand marker-trait association analysis (MTA) in Vaccinium, exploiting the shared ancestry of Vaccinium crops; (2) identify DNA markers linked to fruit characteristics and elucidate how and which fruit characteristics affect fruit quality, relative to consumer preferences, decay during mechanical harvest, processing and distribution; (3) develop DNA assays to implement MAS in core Vaccinium core breeding programs with a common focus on fruit quality traits; (4) enlarge market potential, and increase consumption of Vaccinium fruits by using socio-economic knowledge of consumer preferences to inform breeding; and (5) enhance sustainability of cultivar development by transferring MAS technologies to public and private U.S. Vaccinium breeding programs through training current and future breeders as well as engaging the production, distribution, processing and marketing sectors, allied scientists, and consumers. This Coordinated Agricultural Project proposal addresses SCRI Focus Area 1 (70%) and Focus Area 2 (30%).

Goals / Objectives
Status: Vaccinium (blueberry and cranberry) breeders have little empirical data to assign level of importance to fruit characteristics (FCs) relative to consumer preferences, decay during production, processing and distribution, and few tools to select for high fruit quality. As a result, blueberry and cranberry cultivars often produce fruit with inconsistent appearance, texture and sensory profiles that do not consistently meet consumer expectations, processing and production quality needs. The Vaccinium industry recognized the need to improve fruit quality as the key breeding target for continued success.Mission statement: Address major bottlenecks for growth of U.S. Vaccinium industry, by creating a nationwide coordinated transdisciplinary research approach to develop and implement marker assisted selection (MAS) capacity in Vaccinium breeding programs, to enable breeders to select and pyramid fruit characteristics (FCs) that positively contribute to fruit quality and market value. In the long term, this mission will increase production of fruit with improved characteristics that meet the ever-changing industry, market, and consumer preferences.Specific project objective are: 1) Establish genomic resources to enable effective association mapping studies in blueberry and cranberry; 2) Discover DNA markers and fruit characteristics that maximize industry profitability and match consumer preferences in blueberry and cranberry; 3) Deliver molecular and genetic resources to improve blueberry and cranberry fruit quality traits that maximize industry profitability and match consumer preferences; 4) Assess the potential socio-economic impact of blueberry and cranberry fruit quality improvements on market demand; 5) Engage U.S. Vaccinium breeders and stakeholder groups to transfer advanced phenomics and genomics tools to build a more coordinated and efficient cultivar development system.
Project Methods
Obj. 1.The comparative genomic team will use a selected set northern highbush (NHB), southern highbush (SHB) and cranberry (CB), to assemble the pangenome that is aimed at identifying the core and dispensable portions of the genome. The core genome represents genes shared by all genotypes, whereas the dispensable portion includes the genes present only in a subset of the genotypes. Core genomes will be compared to identify the core genes shared by NHB, SHB, and CB. The genotyping team will use the pangenome as a reference to identify SNPs, test and validate a cost-effective high-throughput genotyping platform.Obj. 2.The statistical genetics and phenomic teams (blueberry and cranberry) will use high-throughput genotyping platform and phenomic approaches to identify alleles for fruit characteristics (chemical composition, texture, and appearance) by QTL and GWAS analysis. The fruit quality team will use a pre-selected set of blueberry cultivars to identify blueberry FC sub-components (eg. firmness, sugars) that contribute to extended shelf life, meeting consumer preferences and to reduce bruising damages during mechanical harvest. This outcomes, will allow us to establish a link between DNA markers associated with FCs, and fruit quality attributes.Obj. 3. The statistical genetic team will validate FC-QTLs across multiple genetic backgrounds. Validated FC-QTLs will be used as a target site to develop and validate a high-throughput affordable assay for Vaccinium FCs, that can be used to implement marker assisted selection (MAS). The breeding teams will use validated SNPs to identify breeding parents and 'pyramid' multiple positively associated markers into superior genotypes. Multiple superior FCs allele donors, and F1 progenies with pyramided FC alleles will be made available to breeders U.S.-wide.Obj. 4.The socio economic team will combine blueberry sensory tests and choice experiments, biometrics parameters and willingness to pay elicitations to identify FCs and sensory characteristics that affect (positively and/or negatively) purchasing behavior. For cranberry, an online survey and a choice experiment will be conducted with a representative sample of U.S. consumers to (a) quantify consumerss discount for cranberry products with an "added-sugar" line on the nutrition facts panel label, (b) measure heterogeneity in responses across consumer segments, and (c) evaluate the effect of information framing. The results will be used to assess consumers' accuracy in evaluating sugar content and evaluate how this affects purchase intent and willingness to pay.Obj. 5.The Extension team and the Data Management teams, in collaboration with all project participants will develop multiple outreach activities/tools (on-line platforms, webinars, workshops, forums, coomodity group meetings) to engage Vaccinium stakeholders by: 1) transferring and training them on project deliverables, 2) educating them about project outcomes, 3) fostering new collaborations, and 4) soliciting feedback on the project to fine-tune research and extension activities. Target stakeholders are national and international blueberry and cranberry partners that represent breeders, researchers (breeder's allied scientists), mentees/trainees (staff, mentored students and post docs), extension specialists, industry stakeholders (producers, processors, distributors, and nurseries), as well as the members of the Advisory Panel (AP) that represent these audiences. An external evaluator will work with the Project Management and Extension Teams to regularly gather, analyze, and interpret feedback from breeders and extension audiences, including systematic collection of input on project goals, activities, progress, mid-course corrections, and communication and extension strategies.

Outputs
Target Audience:Blueberry and cranberry breeders; post-harvest physiologists, food scientists, germplasm collection curators, molecular geneticists, and other allied scientists of these crops; nurseries, producers, processors, marketers, and marketing organizations of Vaccinium crops; and consumers of these crops. Changes/Problems: Due to operational restrictions (total or partial lockdown) employed by funded institutions to prevent the spread of COVID-19 infections and delay of funding release from the USDA-NIFA the following activities were not performed as planned: sequencing of the 36 blueberry and cranberry samples was delayed resulting in a delay in downstream analysis (Obj. 1); Southern Highbush GenStudy set was not harvested and phenotyped (Obj. 2); the cranberry diversity panel could not be transplanted in the field (Obj.2); one newsletter could not be developed; workshops that were to be held at the Vaccinium International Symposium could not be organized (symposium was postponed to 2021); the first annual meeting was organized on-line. Furthermore, engagement with the public and commodity groups was limited due to shutdown of physical meetings due to COVID-19. To compensate for some of these delayed and cancelled activities, some data analysis work from complementary projects was completed (eg. completed additional chromosome scale genome assemblies and performed comparative analysis, completed linkage maps and QTL mapping for SNPs catalog, identified possible genes and SNPs from existing QTLs to target for DNA assay design) and are being used to complement VacCAP planned activities. What opportunities for training and professional development has the project provided?Project participants include 5 post-doctoral associates and 15 technicians, 13 graduate students and undergraduate students fully or partially funded by the project across all the VacCAP team programs. These trainees and technicians are participating in VacCAP activities of phenotyping, genomic analysis, DNA profiling, development of DNA-informed breeding strategies, data management and communication. These personnel are gaining knowledge, experience, and skills in accurate measurement of fruit characteristics, fruit physiology, phenotyping engineering, quantitative genetics, bioinformatics, design and implementation of genetic tests, and breeding program planning and management. In addition, these participants are members of project Teams and undertake targeted training such as a workshop and a one to one in person training on texture analysis. How have the results been disseminated to communities of interest?Introduction about the VacCAP project, and preliminary results were disseminated to the scientific community, including the U.S.-wide community of Vaccinium crop breeders, through 8 peer reviewed publications, 11poster and oral presentations at regional, national and international conferences (including Plant and Animal Genome Conferences). The information was also disseminated to the broader Vaccinium community (producers, processors and distributors) through 14 oral presentations at commodity group meetings, 2 article in trade magazines, 7 news articles, and the VacCAP newsletter. To engage the public and students, VacCAP PIs, participated in and/or organized eight outreach events targeting K12, middle, high schools, and college students including students representing minorities. Events include blueberry and cranberry field trips, science fairs, and short lab training classes. Outreach activities aimed at introducing students to plant science and horticulture, food science, scientific lab experience based on protocol/research. All these activities placed specific attention on the importance on the central role of breeding for blueberry and cranberry productions but also more general crop productions. Lab activities include DNA extraction, PCR, basic chemistry analysis (eg. pH, Brix) and sensory analysis. These events attract thousands of attendees and contribute to enhance public understating and interest in learning and careers in plant science, and more specifically plant breeding. What do you plan to do during the next reporting period to accomplish the goals?Objective 1. Establish genomic resources to enable effective association mapping studies in blueberry and cranberry.

Impacts
What was accomplished under these goals? Project Objectives and Annual Progress Obj.1. To develop the Vaccinium pangenome the genomes of 36 blueberry and cranberry cultivars were sequenced and the assembly for fifteen genotypes was completed. Three chromosome scale genome assemblies representing blueberry wild diploid species and one cranberry cultivar were completed, and three new linkage maps were constructed. These resources are used to improve the quality of the available blueberry and cranberry genome assemblies, and for genome-wide analyses to identify regions of the genome that contain introgression from related Vaccinium species used by various breeding programs. The pangenome will be used to develop a high-throughput genotyping platform (HTGP) and will limit ascertainment bias in the SNP selection. Multiple activities were initiated to develop the Vaccinium HTGP. SNP markers (47,025) from blueberry and cranberry linkage maps and QTL studies and 667 DNA and RNA sequence sets of Vaccinium genotypes were collected to establish a catalog of Vaccinium SNPs to detect and validate new SNPs. Plant material was collected from blueberry (188) and cranberry (100) genotypes to use for testing the Vaccinium genotyping platform. Engaged 18 core and non-core labs (stakeholders) to evaluate the technical needs for a Vaccinium HTGP. Feedbacks highlighted the following platform needs: cost effective; able to estimate allele dosage; limit ascertainment bias; serve multiple applications, in particular GWAS; and be easy to use via limiting work needed for scoring the SNPs. Overall the outcomes of these activities lay the foundation to build the resources and the network needed to expand application of molecular tools in blueberry and cranberry breeding and genetic programs. Obj.2. To perform marker traits association studies for fruit characteristics (FCs) and shelf-life indicators, new phenotyping methods/protocols were tested and implemented to phenotype the blueberry and cranberry Genetic Study sets. Blueberry: Developed a data collection system to simultaneously evaluate and collect phenotypic data for 20 FCs representing texture and appearance, shelf life indicators (wrinkle, mold, and leakage) and to calculate storage performance (eg. FCs storage indexes). Fruits from the Northern Highbush (NHB) GenStudy set (N=973) and one mapping population (DxJ, N=189) were phenotyped at harvest and six weeks post-harvest (stored at 4?). Preliminary results indicates a wide range of variation for most of the traits. Fruits for non-volatile chemistry analysis are being processed by the Phenotyping team. To identify FCs that contribute to fruit quality traits, a new subset of texture parameters and indexes were tested using three methods (penetration, compression and puncture). The new parameters are being correlated with sensory analysis, shelf-life indicators and with a handy fruit texture analysis device. Preliminary analysis indicates that the different methods can discriminate genotypes, and in some case the different tissue layers. Also method for chemical compositional analysis are being tested, and along with the texture analysis will be used to establish a link between DNA markers associated with FCs and fruit quality attributes. Cranberry: three methods (puncture, compression, and shearing) for texture analysis were evaluated. The compression method was the most powerful to discriminate cultivars and was chosen for downstream analysis. Texture, external appearance, internal appearance, non-volatile chemical composition was phenotyped on 3 mapping populations (MP1, N= 171, MP2, N=71, MP3, N=211) and resistance to fruit rot evaluated in MP3. Preliminary analysis indicates a wide range of variation for most of the traits. The use of accurate and objective phenotypic methods to evaluate FCs in blueberry and cranberry, represent a key step to empower the following up marker traits association studies. Obj. 3. To validate existing and/or new FCs QTLs, a subset of the Validation Study set (161 NHB blueberry genotypes) was phenotyped for FCs, shelf-life indicators and storage performance and are being processed for non-volatile chemistry analysis. Cranberry advanced selections bred for fruit rot resistance (FRR) were also evaluated. Phenotypic data obtained from the ValStudy and GenStudy sets are also being analyzed to identify parents carrying desirable FCs and to use them in new crosses. To develop simple DNA assay targeting FCs, data from previous blueberry and cranberry QTL studies were used to identify target candidate genes. NBS-LLR resistance genes and genes involved in the synthesis of volatile (VOC) metabolites, and anthocyanin (ANT) were identified in the cranberry and blueberry genomes. A genetic study for citric and malic acids (CITA) in cranberry was completed and a multi-allelic Mendelian locus CITA identified. The genomic location of existing FRR, ANT, CITA and VOC QTLs are used to identify their overlap with candidate genes. Also DNA extraction and genotyping high-throughput assays for blueberry were started. This activity establishes a foundation to validate existing and new FC QTLs, and develop cost-effective DNA assay. DNA assay for FCs and new crosses made based on molecular and phenotypic data will provide a foundational work to accelerate breeding for fruit quality in blueberry and cranberry breeding programs. Obj. 4. Finalized the development of a survey to elicit preferences and willingness to pay for different levels of sugar content in dried cranberry and cranberry juice. The survey will also collect information on consumers' perceptions of food science and technology, and the tradeoffs to accept novel breeding technologies when the benefit is to receive a healthier (less sugar) product. Cranberry industry stakeholders actively participated on designing the survey and distribution of the survey is being planned. The outcomes of this study will guide cranberry breeders and the processing/distribution industry in formulating targeted marketing strategies for the promotion of cranberry products. Obj. 5. All activities aiming at engaging the stakeholders were initiated during year 1. On-line platforms: the VacCAP web site was released. The Genome Database for Vaccinium was updated, by adding new genetic and genomic data (see other products) and upgraded to the Tripal 3 database platform. Created a standard Blueberry Trait Ontology in collaboration with USDA ARS scientists for use in both the Breeding Insight and BIMS platforms. Newsletters and other media: developed and released the first issue of the VacCAP newsletter. Published two articles in trade magazines (see products) to introduce the objectives of the VacCAP project. Created and maintained a VacCAP Twitter account (58 follower) and established a YouTube channel with one video currently uploaded (19 views). Webinars: delivered a webinar titled to introduce the Breeding Information System Management (BIMS) and the Field Book App. The webinar resulted in 11 new BIMS user accounts being created. Workshops: delivered three workshops with cranberry processors to introduce high throughput FCs analysis including texture. Industry representatives expressed interest in implementing the new technologies in their processing lines. Commodity group meetings: Delivered 14 presentations at grower association meetings across nine US states and Canada to introduce the VacCAP project. Annual meeting: the first VacCAP annual meeting with members of the Advisory Panel was organized on-line on Feb. 25, 2020. Panel recommendations were discussed at the annual project meeting, and appropriate adjustments made to project activities. Project evaluation: developed an online survey portal for gathering input from participants in project webinars, workshops and meetings. Feedback and recommendations gained from year one activities are being considered in planning future activities.
