DNA profiling of sweetpotato cultivars and clones

This file is about:

  • DNA testing, DNA typing, genetic fingerprinting
  • Majority of DNA is the same for organisms in the same species but there are pieces, regions/patterns that differ within the species
  • Knowing these DNA sequences is the basis of DNA profiling
  • DNA sequencing; determining the nucleotide sequence of a given DNA fragment
  • Knowing the sequence of DNA fragments can help the sweetpotato breeder/researcher to apply molecular markers in sweetpotato breeding to:
    • Cultivar identification
    • determination of ‘hybridity’
    • Assess genetic diversity
    • genetic mapping
    • gene tagging
    • gene flow
    • molecular evolution study
