From Wikipedia, the free encyclopedia
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.

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."
