What is Backcross Breeding – Definition?

Backcross method is named as “Backcross breeding”.

Backcrossing has been used by plant breeders for decades to transfer specific character into elite lines. The variety which receives gene is ‘recipient parent’ and variety which is the source of gene is called as ‘donor parent’. Recipient parent is used repeatedly hence also named as ‘recurrent parent’. Donor parent is ‘non-recurrent parent’. Repeated backcrossing leads to homozygosity at the same rate as in case of selfing.
