Backcross Breeding

  • P. M. Priyadarshan


A cross between F1 hybrid and one of its parents is known as a backcross. Harlan and Pope in 1922 first proposed backcrossing as an appropriate breeding method for cereal crops. Since then, backcrossing became a widely accepted breeding strategy in diverse crops. This is used to transfer one or a few traits into an adapted/elite variety. Mostly, the elite variety used for backcrossing (called the “recurrent parent” or “recipient parent”) used to have a large number of desirable attributes but may be deficient in a few traits. The other parent, called the “donor parent” (or “non-recurrent parent”), lodges one or more traits that is lacking in the elite variety, but with poor agronomic traits.
