Progress 09/01/20 to 08/31/21
Outputs Target Audience:Raising awareness and implementation of the constantly improving computation tools is essential to increase their use and subsequently accelerate the breeding progress of a wide diversity of polyploid crops including root/tuber crops (28%, potato, sweetpotato, yam), fruit (29%, blackberry, blueberry, banana, coffee, kiwifruit, strawberry), turfgrass, forage, sugarcane (19%), ornamentals (9%. Rose. chrysanthemum), vegetables (11%, legumes, asparagus, mint, basil), cereal (4%) and a few forest tree species. Our audience is young (64% less than 40 years old) and with no experience (90%) with the software. Many were either postdocs, graduate students (40%) or young breeders. Their training is essential to incorporating these tools into the breeding programs of the future. The expertise of our audience was on breeding/genetics (40%), computational genetics (20%), molecular genetics (25%) as well as entomology, plant pathology and plant physiology. The breeding programs ranged from small (1000 seedling per year) to very large (over 100,000 seedlings per year) representing both private (37%) and public (63%) programs. Fifty-four percent of our audience is from North America(38 states and Canada) and 46% from international locations, mainly South America, Europe and Africa but also Asia and Oceania. There was high participation from International Research Station (CGIAR) scientists. Changes/Problems:

What opportunities for training and professional development has the project provided?The major training event for polyploid crop breeders, their support people (bioinformatists, computational geneticists, molecular geneticists, plant pathologists, entomologists), post doctoral associates and graduate students was the 2021 Tools for Polyploids Training Workshop which was done as an online conference. This included presentations about the current computational tools for genotyping, map construction and QTL identification followed by question and answer sessions for each software suite. The attendance was superb with 353 people registering and a mean attendance over all three days of 250 participants. The 16 presentations were recorded and put on the Tools for Polyploids Youtube (https://www.polyploids.org/workshoppresentations) channel. They have received 1,137 views. and subsequent questions and trouble shooting was handled via the Tools for Polyploids SLACK channel (279 subscribers). In addition, Jeff Endelmann gave a presentation to the potato group about the use of genomic selection in their breeding programs and various PIs, graduate students and post doctoral researchers participated in professional meetings (PAG, ASHS, American Potato Society etc). How have the results been disseminated to communities of interest?During the first year of the project we have communicated progress to our scientific colleagues (7 journal articles, 4 non referred articles, 25 presentations). The major communication event for polyploid crop breeders, their support people (bioinformatists, computational geneticists, molecular geneticists, plant pathologists, entomologists), post doctoral associates and graduate students was the 2021 Tools for Polyploids Training Workshop which was done as an online conference. This included presentations about the current computational tools for genotyping, map construction and QTL identification followed by question and answer sessions for each software suite.

They have received 1,137 views. and subsequent questions and trouble shooting was handled via the Tools for Polyploids SLACK channel (279 subscribers). The Tools for Polyploids web site (https://www.polyploids.org/) serves as a repository of information about the project (1,738 visitors since January 2021) as well as a project management tool. The most popular section are the recorded presentations from the first conference which are used as a guide in using the software. The Tools for Polyploid Twitter account (Twitter @toolsforpolyploids, 139 followers) as well as periodic email alerts/surveys (400 people on mailing list) are used to keep our clientele informed of our activities and other polyploid related activities. What do you plan to do during the next reporting period to accomplish the goals?

Impacts What was accomplished under these goals?
Objective 1. Develop computational tools for genomics-assisted breeding in polyploid crops. Obj. 1a. Enhanced methods for genome-wide association studies GWASpoly was improved by optimizing the control of the genome-wide false positive rate, enhancing the calculation of the kinship matrix, using the ggplot2 package, including a plotting function for LD, enhancing the ability to filter QTL output based on a specified LD window, and updating the vignette to illustrate the new features. Obj. 1b. Linkage/QTL analysis and genomic selection in multi-parent populations The interoperability among the programs such as MAPpoly, QTLpoly, polymapR, polyqtlR, updog, polyRAD and fitPoly was improved. MAPpoly updates include the addition of the probabilistic computation of two-point recombination frequencies used in polymapR for dosage-based probabilistic map construction, the fast implementation for plot large recombination frequency matrices, the functions to plot genetic information content (GIC), to read VCF and fitPoly files, probabilistic information, to upload datasets from the R packages updog, polyRAD and to import/export map results from/to polymapR, and the implementing of a multiparental mapping strategy for polyploid species. QTLpoly improvements include support for linkage maps constructed by MAPpoly and polymapR, a final QTL model that can be used to implement genomic prediction and the ongoing expansion of QTLpoly to support multiparental and multi-generational breeding populations. VIEWpoly is being developed to produce a graphical representation of the genetic map which shows marker names, parental dosages, and the linkage phase configuration of the allelic variants With QTLpoly it shows estimated positions, effects, and supporting intervals of QTL along the genome. polyqtlR has been updated to include new visualizations of chromosomal pairing patterns across populations, automated co-factor analyses and multi-QTL model building. Obj. 1c. Polyploid haplotype assembly from short reads Developed "MCHap" for assembly of micro-haplotypes in polyploids using Markov chain Monte Carlo simulation and standard bioinformatics file formats to ensure compatibility with existing software. This software assembles known multi-allelic SNPs into haplotypes within pre-defined genomic loci, calls or recalls genotypes based upon sets of known haplotypes across the genome and reports full posterior distributions for haplotype assemblies. It is designed to be run in parallel across multiple genomic loci for efficient use in an HPC environment. Objective 2. Validate computational tools Obj. 2a. Allele dosage assignment fitPoly use was facilitated by consolidating a set of software tools for data formatting and curation into the R package fitPolyTools. SNP-calling (GATK, freebayes, TASSEL, DeepVariant and proprietary software) and dosage calling (GATK, freebayes, updog, polyRAD and superMASSA) pipeline comparisons using sequence data are being performed using Workflow Description Language with the support of Docker/Singularity containers to facilitate higher accessibility, interoperability, reproducibility, and reusability of the pipelines. The comparisons will assess the marker position compatibility between methods, genome coverage and genetic map quality. Obj. 2b. Genome-Wide Association GWASpoly was used on roses, blackberries, potatoes, and turfgrass this past year to identify marker-traits associations for disease resistance, productivity, plant architecture, flowering type, and fruit/ tuber quality. In rose, the GWASpoly results were congruent with QTL scans. Obj. 2c. Linkage and QTL Analysis Linkage maps and QTL analysis using Mappoly/polymapR and/or QTLpoly/polyqtlR have been done in roses, blackberry and sweet potato. Comparisons of polymapR/MAPpoly for linkage mapping and polyqtlR/QTLpoly for QTL analysis with tetraploid rose families reveal software differences in the ease of use, computational demand, map quality and QTL positioning. The multiparental joint mapping function of MAPpoly was tested on crosses between three sweetpotato varieties: Beauregard, Tanzania, and New Kawogo (723 genotypes, 28.220 SNPs). A joint map and the haplotype reconstruction was consistent with previous work with biparental populations (Pereira et al., 2020). Work continues to improve the efficiency of the function by lowering the computational resources needed. Obj. 2d. Genomic Selection Potato breeding programs in New York, Minnesota, Maine, Oregaon, Texas and Wisconsin collected performance and genotype data on seedlings and variety checks to initiate genomic selection with the coordination of Jeff Endelman. Endelman has delivered training in the use of the StageWise genomic selection software suite to the collaborating potato breeders (see StageWise case studies (https://github.com/jendelman/StageWise). Obj. 2e. Sequence-based haplotyping Comparative Subsequence Sets Analysis (CoSSA). which uses set-theoretic operations on k-mers to identify haplotype-specific variants in heterozygous individuals is being tested to assess its utility to identify haplotypes for KASP marker development for a late blight R gene in potato. The beta version 0.5.1 of MCHap been successfully used to haplotype 800 tetraploid kiwi samples across ~10,000 loci (PFR). Objective 3. Train polyploid breeders and geneticists 3a. Develop written documentation of software tools The tutorials and reference manuals for the software have been updated and can be found at the following locations: GWASpoly and StageWise at https://github.com/jendelman. MAPpoly athttps://cran.r-project.org/web/packages/mappoly/mappoly.pdf, and vignette at https://rpubs.com/mmollin/tetra_mappoly_vignette QTLpoly athttps://raw.githubusercontent.com/guilherme-pereira/QTLpoly/master/docs/qtlpoly_0.2.1.pdf and vignette athttps://guilherme-pereira.github.io/QTLpoly/1-tutorial, and the tutorial athttps://guilherme-pereira.github.io/QTLpoly/2-tetraploid_example.html. polymapR at https://cran.r-project.org/web/packages/polymapR/index.html polyqtlR at https://cran.r-project.org/web/packages/polyqtlR/index.html 3b. Prepare and conduct annual short courses Online conference. January 12-15th, 2021. The attendance was superb with 353 people registering and a mean attendance over all four days of 250 participants. Sixteen presentations about the current computational tools for genotyping, map construction and QTL identification were followed by question and answer sessions. The recorded presentations were put on the Tools for Polyploids Youtube (https://www.polyploids.org/workshoppresentations) channel (1,137 views). Subsequent questions and trouble shooting was handled via the Tools for Polyploids SLACK channel (279 subscribers). Starting with a group of which ~90% were not familiar with the software presented, 90% were extremely or moderately satisfied with the presentations and about 50% of the participants were planning to use the software presented in the coming year. 3c. Develop a Tools for Polyploids Community Resource web page The website (polyploids.org) currently holds project information (history, participants, activities), software links, recorded presentations, recent publications, and news articles related to the project. We are working towards creating a space to house project members' data and serve as a one-stop-shop for each team to share their progress. Since its creation in January 2021 it has had 1,738 visitors. 75% of the visitors are younger than 44 and hail from North America (73%) and various countries in South America, Europe Asia, and Oceania. The most popular feature are the recorded presentations from the 2021 Tools for Polyploids Training Workshop (Tools for Polyploids). Associated social media include the Twitter @toolsforpolyploids account created in November of 2020. It currently has 139 followers and 1,107 profile visit per month.
