Resistance breeding is done by Back crossing.
Resistance breeding is an important strategy for reducing crop losses caused by disease.
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. It is used in horticulture, animal breeding and production of gene knockout organisms.
