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]

Modern biotechnology has broadened the options for stacking to include more taxonomically diverse sources, a wider selection of genes and regulatory elements, and consequently of traits."
