Project at a Glance Contents on the CD ROM
  • A doubled haploid (DH) is a genotype formed when haploid cells undergo
    chromosome doubling.
  • Artificial production of doubled haploids is important in plant
    breeding.
  • For doubled haploids to become a valuable breeding technique, it is necessary that success of doubled haploid production is not genotype dependent, the protocol used is efficient in time and cost.
  • Benefits of this technology are ,Double Haploid technology creates true-breeding lines in a single step, Combined DH & molecular marker technologies result in increased rates of genetic gain, Facilitates multiple trait stacking/pyramiding, Increases efficiency & probability of successful product development , Reduces time to market.
  • Double haploids are a product of modern technology which uses microspores to achieve a uniform parent line (homozygous) from very early generations of breeding material. This technique eliminates the need for several generations of breeding crosses.
  • Double haploids are also used to efficiently develop molecular mapping populations and ensure traits are uniformly expressed in a plant. This one step process replaces
    previous methods which could take up to six generations of plant growth.
  • Doubled-haploid technology enhances “forward breeding” by allowing hybrids to be bred with new traits (GMO and non-GMO) without locking up the germplasm, and by developing stacks without negative side effects.
  • The doubled-haploid method is much faster and can produce a new, genetically stable inbred line in one year.
  • The doubled-haploid method greatly reduces the time required to develop new parent inbreds.
  • The relevance of DHs to plant breeding has increased markedly in recent years owing to the development of protocols for 25 species.
  • Doubled haploidy already plays an important role in hybrid cultivar production of vegetables, and the potential for ornamental production is being vigorously examined.
  • The other advantages include development of large number of homo-zygous lines, efficient genetic analysis and development of markers for useful traits in less time.
  • Tobacco, rapeseed, and barley are the most responsive species for doubled haploid production.
