THE DEVELOPMENT OF SALT-TOLERANT TOMATOES: BREEDING STRATEGIES |
| Author: | R.A. Jones |
| Abstract:
Crop improvement objectives are rapidly changing to include greater production efficiencies with fewer inputs as well as expanding agricultural productivity onto marginal lands. To meet these objectives, crop cultivars which can be productive under less than optimal conditions will be required. Breeding for salt-tolerance to increase agricultural production and stabilize productivity will be increasingly important. Plant genotypes can be developed which perform better under stress, although certain difficulties are inherent in this approach. The identification and exploitation of useful heritable variation in tomatoes has only just begun. The following discussion will focus on present constraints sorrounding the development of salt tolerance in tomatoes with special emphasis on the requisite development of breeding strategies for improving salt-stress resistance. | |
