Gene pyramiding

Gene pyramiding is the simultaneous selection for and/or introduction of multiple genes during plant breeding.[Taverniers et al 2008 1]​ For example, pyramiding has been successfully demonstrated in Oryza sativa for rice blast, producing durable multi-race resistance simultaneously.[1] Pyramiding and Marker Assisted Selection can be combined as Marker-Assisted Pyramiding.[2] Gene stacking can be achieved a few different ways, and pyramiding is one of those methods.[Taverniers et al 2008 2]​

It is essentially a way of identifying and introducing multiple genes, which each impart resistance to an independent insect/microbial pest/weed etc., or impart resistance to a single pest through independent host pathways."
  2. p. 199, "Independent of modern biotechnology, “stacking” traditionally refers to the natural addition of different plant properties by genetic crossing. 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."
