Presenter Information
Dr. David Byrne (PD), the Basye Endowed Chair in Rose Genetics, and a Professor in Horticultural Sciences at Texas A&M University. He works internationally in Prunus and Rosa breeding and genetics. He led the SCRI Combating Rose Rosette Disease project, worked with the SCRI RosBREED 2 project, and currently chairs the National Clean Plant Network for Roses. He routinely works with numerous scientists, private breeding programs, ornamental nurseries, marketers, and producers as well as ornamental hobbyist groups. He has, in collaboration with Dr. Klein, developed a GBS pipeline for Rosa, created high density rose maps, and is working with Dr. Riera-Lizarazu to incorporate genomic approaches (MAB, GWAS, GS) into the rose breeding program to enhance disease resistance (RRD, black spot, cercospora), flower productivity, and horticultural quality of roses. Over the past decade, he has mentored 18 graduate students, published 37 refereed and 27 non refereed publications, has given about 140 talks, and released 23 Prunus and 6 Rosa cultivars. He reaches out to the rose community via Facebook and with Rose Updates. He is the Project Director and will coordinate the training aspects of the project and work with Drs. Riera-Lizarazu and Klein on the validation of the computational tools on multiple rose datasets. He will discuss the unique challenges of the polyploid crop breeding community and summarize survey results on the status of genomics-assisted breeding among our community. |
Delany Baum, Project Coordinator: Delany graduated from the University of North Texas in 2020 with a Master of Science degree in Environmental Science. She has a background in environmental education and has conducted research in the fields of plant physiology, ethnobotany, and ecology. Delany is the project coordinator for the Tools for Polyploids project and oversees the project's social media pages and website. |
Dr. Dorrie Main is a Professor of Bioinformatics in the Department of Horticulture at Washington State University. She runs a highly collaborative, multi-disciplinary research program that has been funded through public (NSF, USDA) and industry (cotton, tree fruit, and legume) sources. The research develops database resources for specific crops (e.g., Genome Database for Rosaceae, CottonGen, Citrus Genome Database, Cool Season Food Legume Database, Genome Database for Vaccinium), online computational tools (e.g. GenSAS), sequence analysis pipelines (e.g. RefTrans), and generic database platforms (e.g. Tripal). The lab also identifies genomic regions and markers controlling important traits and studies genome evolution (e.g. synteny analysis in horticultural crops). All of these efforts seek to provide genomic, genetic, and breeding resources to enable basic, translational, and applied research. They are active members of the AgBioData Consortium and host the AgBioData website. |
Originally with a background in physics and pure mathematics (UCC Cork, Ireland), Dr. Peter Bourke has also trained in horticulture and permaculture design. He worked for over four years in vegetable seed production and genetic resource conservation with the Irish Seed Savers Association, Ireland. Peter gained a Master of Science degree in Plant Sciences from Wageningen University & Research in the Netherlands and continued with doctoral research into polyploid quantitative genetics and mapping under the guidance of Prof. Dr. Richard G.F. Visser, Dr. Chris Maliepaard, and Dr. Roeland E. Voorrips. He graduated in 2018 and now works as a researcher and lecturer in the Plant Breeding group in Wageningen. |
Dr. Chris Maliepaard joined Wageningen University – Plant Breeding in 2007. He is currently associate professor and research group leader of a group working on ‘Quantitative Aspects of Plant Breeding’. He carries out research projects about mapping, QTL analysis and marker-assisted selection, mostly related to polyploid crops; other research focuses on prediction of phenotypic traits from ~omics data sets. His line of expertise is on plant breeding, quantitative genetics, statistics and quantitative analysis aspects of systems biology and bioinformatics. He teaches about these topics in several MSc, PhD and international courses. In an earlier phase in his career, Chris was employed at the quantitative genetics and statistics group at Biometris, Wageningen, working on statistical analysis of large data sets, and he did consultancy of breeding companies on statistical and quantitative genetics topics. |
Dr. Roeland Voorrips is a senior researcher at Wageningen Research – Plant Breeding. After his study Plant Breeding at Wageningen University he was employed at a vegetable seed company before joining Wageningen Research in 1986. He has studied disease and pest resistance in many vegetable crops, and he has been working on quantitative and population genetics methods, including linkage and QTL mapping. Since 2010, he became involved in the development of genetic tools for polyploid crops. He has published several genetics software packages, including MapChart, Pedimap, PediHaplotyper, fitTetra / fitPoly and PedigreeSim, and contributed to others including joinmap and polymapR. |
Dr. Marcelo Mollinari is a Senior Research Scholar at North Carolina State University working with the genetics of complex polyploids. He is the creator and maintainer of the R package MAPpoly, which will be one of the topics of the Tools for Genomics-Assisted Breeding in Polyploids Training Workshop. Marcelo also co-created OneMap, an R package for linkage mapping in outcrossing species. In 2008, Marcelo started working on the genetics of polyploids at the University of São Paulo, Brazil. He published works on assessing dosage-based markers in sugarcane and assisted the development of the software SuperMASSA. In 2014, he was a Visitor Researcher at Purdue University where he continued his studies on genetic linkage in polyploids, with particular focus on high-level ploidy species. In 2016, he started to work on the Genomic Tools for Sweetpotato Improvement project, being responsible for the genetic mapping of several biparental hexaploid sweetpotato populations. During that project, he implemented MAPpoly and built three ultra-dense multilocus genetic maps with the reconstruction of the full haplotypes of the parents and offsprings. The resulting maps served as the basis to study the inheritance patterns and meiotic behavior of sweetpotato as well as QTL and genomic selection. He also consults with researchers from several other polyploid species, such as potato, forage crops, kiwifruit, and strawberry.

Dr. Patricio Munoz is an associate professor leading the blueberry breeding and genomics program at the University of Florida Horticultural Science Department www.blueberrybreeding.com. He obtained his M.Sc. in quantitative genetics and Ph.D. in Molecular Breeding at the University of Florida. He then led the Forage breeding and genomic program at the University of Florida Agronomy Department before moving to his current position. His research consists in the improvement of cultivars with a local focus but a global impact, and in developing and implementing genomic tools to accelerate the breeding process with a focus on outcrossing polyploid species. He has released or collaborated for the release of 10 blueberry cultivars, 4 forage cultivars, and 7 turfgrass cultivars. He also led the development of one phone App for helping growers with scouting blueberry pests and diseases, as well as to obtain details of blueberry cultivars (UF/IFAS Blueberry Growers App). Currently, he is working to develop low chilling requirement blueberries with better flavor, sensorial and nutraceutical traits to enhance the consumption of blueberries while still working on traditional crop traits that help producers stay competitive. |
