In back cross breeding repeated crossing. With recurrent parent is done to Completely recover the genotype of recurrent parent.
Backcross breeding enables breeders to transfer a desired trait such as a transgene from one variety (donor parent, DP) into the favoured genetic background of another (recurrent parent, RP).
If the trait of interest is produced by a dominant gene, this process involves four rounds of backcrossing within seven seasons.
