In vitro regeneration and improvement in tropical fruit trees: An assessment

Abstract

In vitro regeneration protocol has been developed for many tropical fruit trees by using juvenile as well as mature explants. Regeneration via somatic embryogenesis have been obtained in a number of cases e.g., while in citrus, sugar apple and papaya, etc. induction of androgenic haploids are successful, in guava and feijoa only callus results in anther cultures. Somaclones have helped in the selection of seedless Musa. Synthetic seed technology has aided in raising plantlets from encapsulated embryos of guava, mango, papaya, etc. Gene transfer techniques can further prove to be useful in the improvement of varieties. © 2005 Springer Science + Business Media, Inc.
