Advantages and Disadvantages

Advantages and Disadvantages
  • Used for the induction of CMS
  • It is a cheap and rapid method of developing new varieties as compared to backcross, pedigree and bulk breeding methods.
  • It is more effective for the improvement of oligogenic characters such as disease resistance than polygenic traits
  • This is the simple, quick and best way when a new character is to be induced in vegetatively propagated crops
  • Most of the mutations are deleterious and undesirable
  • Identification of micro mutations, which are most useful to a plant breeder is usually very difficult
  • Since useful mutations are produced at a very low frequency (0.1%),a very large plant population has to be screened to identify and isolate desirable mutants
  • It has limited scope for the genetic improvement of quantitative or polygenic characters
