Breeding method for transferring monogenic disease resistance from wild species to improved variety of wheat is

The breeding method for transferring monogenic disease resistance from wild species to an improved variety of wheat is the Backcross method.
Backcrossing is a crossing of a hybrid with one of its parents or an individual genetically similar to its parent, to achieve offspring with a genetic identity closer to that of the parent.
Backcrossing and/or convergent backcrossing have been used for transferring resistance to desirable agronomic backgrounds. The number of backcrosses needed to achieve agronomically similar derivatives depends on the donor genotype.
