Plant breeding and in situ utilization of palm trees

the palm tree family (arecaceae) is constituted by approximately 3000 species mainly distributed in the tropics and subtropics. as a source of a variety of products they contribute to the world and local economies, and also to peoples lifestyles. historically their use has been based on wild populations, but also on local domestication. very few species are subject of plant breeding programs and are cultivated in the world. this is the case of the african oil palm (elaeis guineensis), in which investment and development consortiums invest high sums. another kind of crop is the date palm (phoenix dactylifera), which was domesticated thousand of years ago and whose success is based in the export of a fine product with worldwide recognition. in this case the production is based on traditional varieties and has very incipient breeding programs. a third group of palms includes those species from which products are obtained and manufactured for local development. the objective of this literature review is to contribute in the analysis of opportunities and weaknesses to investing in domestication and plant breeding programs in those palm trees with a recognized productive value.
