Morphological Characteristics of Genetically-Modified Pineapple Fruit

O'Hare, T.J., Wong, L.S., Ko, H.L. and Smith, M.K. (2003) Morphological Characteristics of Genetically-Modified Pineapple Fruit. In: Australasian Postharvest Horticulture Conference, 1-3 October 2003, Carlton Crest Hotel, Brisbane, Australia.



Genetic engineering is an attractive method for changing a single characteristic of ‘Smooth Cayenne’ pineapple, without altering its other desirable attributes. Techniques used in pineapple transformation, however, such as tissue culture and biolistic-mediated or Agrobacterium-mediated gene insertion are prone to somaclonal variation, resulting in the production of several morphological mutations (Smith et al., 2002). Fruit mutations can include distortion in fruit shape (round ball, conical, fan-shaped), reduced fruit size, multiple crowns, crownless fruit, fruitless crowns, and spiny crown leaves (Dalldorf, 1975; Sanewski et al., 1992). The present paper describes the variability in fruit-shape mutations between transgenic and non-transgenic fruit, and its subsequent impact on organoleptic characteristics.
