Merits & Demerits of Mass Pedigree Method
Merits
- This method takes 14-15 years to release a variety while bulk method takes much longer time (15-16 years).
- The breeding values of selected plants are ascertained by progeny test.
- Therefore, pedigree selection is based on genotypic value rather than phenotype value.
- Pedigree method provides information about the mode of inheritance of different oligogenic characters which is not possible by other breeding method.
- There is chance of recovering transgressive segregants by pedigree method.
Demerits
- The selected materials become so large that handling of the same becomes very difficult.
- Because large number of progenies is rejected in this method, there are chances of elimination of some valuable materials.
- Records have to be maintained for all the selected plants and progeny which take lot of valuable time of a breeder.
