Radiation Breeding

Overview

Radiation breeding technology is exposing various tissue/organisms such as seeds, plants and tissue culture samples to radiation in order to generate mutants with desirable traits to be bred with original trait. Radiation causing the change (break, substitute, rearrangement) in chromosomes and DNA. Mutation occurring under natural environment condition (spontaneous mutation), therefore radiation breeding is safe and is known as one of breeding method. In worldwide, radiation breeding is applied for development of new cultivars with various crops.

Objectives

  • Development of fusion radiation breeding technology for high efficiency

    ICT based automated phenotyping system

  • Development of useful genetic resources and distribution of registered mutant varieties
  • Supporting for research of industry-university-institute collaboration and formulation of international cooperation project
  • Training of professional manpower in mutation breeding

Research

  • Diversification of using radiation source

    Gamma radiation → particle beam (ion beam, proton beam)

  • Development of genetic resources

    food crops, ornamental crops, eco-friendly crops etc.

  • Basic Research for mutated mechanism using recent -omics tools such as genetics and metabolomics
  • Development and commercialization of useful natural products from mutants
  • Establishment and management of mutant genebank

Major achivement

  • Development of useful genetic resources

    High functional genetic resources: 20 cultivars (Rice, soybean, perilla etc.)

    Ornamental resources for respond to loyalty; 10 cultivars (Chrysanthemum, Rose of Sharon, orchid, pepper etc.)

    Eco-friendly bio industry materials: 5 cultivars(Kenaf, sorghum, microalgae, mushroom etc.)

  • The spread of Radiation breeding and free distribution of registered mutant varieties

    Training course for radiation breeding technology : 20 persons/year (number of trainee)

    Free distribution of registered mutant varieties for farms and organization : 200 times /year

  • Development of fusion radiation breeding technology for high efficiency

    The hardware of ICT-based breeding platform is being built (2018)

  • Development of novel breeding technique using pretreatment of phytohormone
  • Achievement Award(2014.9.)

    Contribution to food security and sustainable agricultural development

Registered ornamental crops

Commercialization of new functional rice varieties

Development of salt tolerance sorghum for breeding in reclaimed field, industrial material using kenaf, and high starch contents of micro algae

Development of new breeding technology using gamma-radiation and proton-beam

Completion of technology transfer for anti-arthritic material from mutant perilla

Distribution of registered variety
