Tools for Polyploids

Polyploid specialty crops contribute significantly to food, fiber and ornamental production, with an annual US crop value of over $9 billion and many times greater globally. Despite the importance of polyploid crops, the implementation of genomics-assisted breeding in these crops has lagged compared to diploid species. A major impediment to using genomic tools is the limited availability of software suitable for polyploids (most tools are developed for diploid crops), technical expertise, and training. The ‘Tools for Genomic-Assisted Breeding in Polyploids’ USDA-NIFA-SCRI project (Award No. 2020-51181-32156) was undertaken to address these deficiencies by developing or extending computational tools for QTL analysis, genomic selection and haplotype analysis in polyploid crops; training polyploid breeders and geneticists to use these tools; and applying the tools for genomics-assisted breeding in public breeding programs for potato, blackberry, turfgrass, kiwifruit, sweetpotato and rose. A key output of the project is a Polyploid Breeding Community Resource web site to serve as a repository of the computational toolsets, genomic information, training datasets from several crops, and training materials..
