Gene pyramiding

Gene pyramiding is the simultaneous selection for and/or introduction of multiple genes during plant breeding.^[1] 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.^[2] For example, pyramiding has been successfully demonstrated in Oryza sativa for rice blast, producing durable multi-race resistance simultaneously.^[3] Pyramiding and Marker Assisted Selection can be combined as Marker-Assisted Pyramiding.^[4] Gene stacking can be achieved a few different ways, and pyramiding is one of those methods.^[5]
