Question
In a breeding program focused on introducing a pest
resistance gene into a commercial crop species, what is the most efficient breeding method if the donor plant is heterozygous for resistance?Solution
Backcross method. This method repeatedly crosses progeny back to one of the parents, aiming to recover the parental genotype while introducing the desired gene. In this scenario, to incorporate a pest resistance gene efficiently, the backcross method is appropriate because it allows the breeder to recover the genetic background of the recurrent parent while selecting for heterozygous resistance.
