Gene pyramiding is the simultaneous selection for and/or introduction of multiple genes during

plant breeding Plant breeding is the science of changing the traits of plants in order to produce desired characteristics. It has been used to improve the quality of nutrition in products for humans and animals. The goals of plant breeding are to produce cro ...

. Objectives of gene pyramiding includes 1) enhancing trait performance by combining two or more complementary genes, 2) remedying deficits by introgressing genes from other sources, 3) increasing the durability. For example, pyramiding has been successfully demonstrated in ''
