DNA sequencing permits the deciphering of the hereditary code, encouraging the disclosure of the atomic hereditary premise of natural frameworks. Information on the arrangement of qualities in grains gives a vital aspect for understanding a significant number of their wholesome and useful properties. For a long time DNA sequencing innovation progressed gradually with steady advances in the di-deoxy or Sanger strategy. New innovations are presently enormously expanding the intensity of DNA sequencing. Second (cutting edge) sequencing has significantly diminished the expense of DNA sequencing and expanded the measure of information that can be gathered. Further advances misusing third era sequencing guarantee to quicken these turns of events. The DNA successions of grain species, genotypes or even individual seeds would now be able to be gotten conveying another degree of capacity in oat science.
