Breeding approaches

Breeding approaches

• The multiplication through vegetative parts in asexually propagated crops provides a unique opportunity to utilize available genetic variation in a single cycle of selection.
  
• Any out standing plant can be multiplied vegetatively producing unlimited number of individuals of the genetic make up.
  
• Since all the members of a clone are simply products of mitosis so these are genetically identical and uniform clone is thus stable over generations of multiplication and variation within clone is due to environmental or mechanical admixture.
  
• Before starting up of breeding programme in asexually propagated crops we have to create variation, utilization of genetic variation to isolate new population and multiplication of successful genotype for commercial cultivation.
  
• The identification and stabilization of desirable genetic variant from variable populations is much easier and relatively less demanding in terms of time and resource.
  
• Asexual reproduction provides a quick and reliable mode of multiplication of the successful clone
