Abstract
Plants of the salt-sensitive L. esculentum, the halophytic wild species L. pennellii, their F1 hybrids and the interspecific F2 generation were grown in Hoagland's liquid culture containing 100 mM NaCl and 6 mM K+. Analysis of the Na+, Cl- and K+ ions contents of the leaves showed, as observed also in previous studies, that the cultivated parent accumlated more K+ and less Na+ than the wild parent. A total of 117 F2 plants were assayed for 15 electrophoretically detectable isozyme markers which map to nine of the twelve tomato chromosomes. Four loci, all with a similar quantitative effect on Na+ and Cl- uptake, were identified by virtue of their linkage to isozyme markers. Two other loci were found to affect K+ uptake. This study demonstrates the potential value of using genetic markers in order to gain a better understanding of the genetic basis of quantitative traits associated with the response of plants to salinity stress.
