Merits & Demerits of Pedigree Method

Merits & Demerits of Pedigree Method
Merits of Pedigree method
  • Excellent method for improvement of easily observable and high heritable characters.
  • As pedigree record is maintained, information regarding inheritance pattern of characters can be obtained as and when required.
  • Each plant can be traced back to its parent plant.
  • Only those progeny lines which contain plants with desired characters are selected for next generation. So there is scope for plant breeder’s skills.
  • Progeny tests are done, thus it is based on genotypic value rather than phenotypic value alone.
  • Increased breeding efficiency by early identification of superior heterogeneous populations
  • Scope for transgressive segregation to occur for the characters like yield.
  • New variety development takes short period as compared to bulk method.

Demerits of Pedigree method

  • Costly
  • Labour intensive.
  • Requires skilled person as selection is practised
  • Pedigree record maintenance is time consuming.
  • Selection for yield or other characters in F2 and F3 is ineffective.
  • One important point to note is genetic variation available for selection gets decreased in later generations due to the individual plant selection carried out earlier
