Development of Core Collections of Genome Resources and Establishment of a Fast-Precision Breeding Platform

    In order to lower the cost of germplasm preservation and increase use efficiency, TARI has built the core collections of major crops, such as tomato and vegetable soybean, utilizing genome-wide genotyping or phenotyping. After eliminating duplications, two core collections of 292 lines of tomato and 226 lines of soybean were established, which accounts for 90% genetic diversity. The next generation of genomics and phenomics analytic technologies were introduced to establish the phenomics databases (more than 20,000 phenotyping records) and the genomics databases (more than 6,795 genome-wide genotyping records) for the core collections of tomato and vegetable soybean. These databases were further integrated into a crop-specific fast-precise breeding platform. However, crop traits are usually affected by the external environment. In addition, traditional breeding still relies on the phenotype investigation of crops. Therefore, the international research community has developed various high-throughput and non-invasive phenomics platforms for efficient plant phenotyping. TARI also has already planned the National Plant Phenomic Center, which is expected to be established in 2023. The center contains the phenomics facilities that can convert the acquired images into crop traits and be powerful tools for botany, plant physiology, exploration of functional genes, germplasm screening, breeding selection, crop modeling, and the interactions of plant-pathogen by equipping with micro weather stations and environmental control greenhouses. Finally, the center can be the basis for developing a fast-precision breeding platform.
