Abstract:

For over a decade cell culture has been advocated in selection programmes for salt tolerance. Selecting cultured cells for survival at high NaC1 potentially offers a fast means for generating, evaluating and selecting genotypes with superior salt tolerance. Furthermore, little space is required and the environment can be controlled. However, plants regenerated from selected cells have not shown unequivocal increases in salt tolerance. Clearly the role of cell culture needs to be reconsidered. This logical
use salt tolerance is multi-genic and depends on the structural and physiological integrity of the whole plant, and partly because of differences in mechanisms of salt tolerance between cells in culture and cells in whole plants. In vitro selection shou
