With the advent of affordable whole genome sequencing and genotyping platforms, tens of thousands of markers can be rapidly developed in any crop, resulting in hundreds of thousands of datapoints even in closely related mapping populations. For example, over 3,000 markers have been mapped using Illumina Infinium chips in both potato and tomato. This has challenged even basic analyses of data, such as the simple generation of genetic maps that geneticists have become accustomed to. Standard softwares are no longer capable of handling these datasets efficiently. We have developed a pipeline to group, order and determine genetic map distances rapidly using the program Record. We then visualize linkage with heat maps using CheckMatrix. This pipeline is presented.

Dr. Allen Van Deynze is a professional researcher at the Seed Biotechnology Center at University of California, Davis. Allen received a BSc. and MSc. degree in plant science from the University of Manitoba, Canada and his Ph. D. in plant breeding from the University of Guelph, Canada. He did a postdoctorate in molecular genetics at Cornell University in the Dept. of Plant Breeding and Biometry. Allen worked as a plant breeder for Calgene/Monsanto and Senior Scientist for Celera AgGen where he developed and implemented strategies to incorporate biotechnology into breeding programs. As part of the SBC’s mission to serve as a liaison between public institutions and seed industry, Allen is responsible for developing, coordinating and conducting research and generating and disseminating scientific and informational content for the Seed Biotechnology Center’s educational and outreach programs. His research focuses on developing and integrating genomics into plant breeding of California crops. He has programs on cotton, lettuce, tomato, potato and particularly developing resistance in pepper to root rot and leaf blight. With Dr. Kent Bradford he co-developed and is organizer for the Plant Breeding Academysm and vice chair of the US Plant Breeding Coordinating Committee.
