In Vitro Strategies for Tropical Fruit Tree Improvement

  • Richard E. Litz

Abstract

Vegetatively propagated tropical fruit trees can be highly sensitive to plant disease epidemics. These trees are usually very heterozygous and have long generation cycles (e.g., 7–20 years). Some tropical fruit species such as mangosteen, which is obligately apomictic (nucellar embryony), are recalcitrant to conventional plant breeding approaches. Strategies for the recovery of horticulturally useful plants from cell and tissue cultures have great potential for the improvement of tropical fruit species. De novo regeneration pathways have been described from explants of selected mature trees of perennial tropical fruit species in Anacardiaceae, Euphorbiaceae, Moraceae, Myrtaceae, Oxalidaceae, Rosaceae, Rubiaceae, Rutaceae, Sapindaceae and Sterculiaceae. The regeneration of tropical fruit trees and the application of the approaches for cultivar improvement are the subjects of this discussion.
