  • Backcrossing involves making an initial cross between the donor and recurrent parents. The resultant F 1 progeny have 50% of their genetic material from each parent (Fig. 1). F 1 individuals are crossed to the recurrent parent to develop a backcross one (BC 1) population.

  • What is the donor parent in backcross breeding?

  • The parent from which one or a few genes are transferred to the recurrent parent in backcross breeding. (has a gene of interest) and a recurrent parent (an elite line that could be made better by adding the gene of interest). The donor parent is crossed to the

  • What is the recipient parent in backcross method?
