uptake and transport in the presence of NaCl. Pigments were severely affected by salt stress in leaves of S. carnosa when compared with leaves of S. coronaria . In addition to these physiological characterisations, genetic diversity was measured between the two accessions using inter simple sequence repeat (ISSR) markers. Three ISSR primers generated a total of 63 DNA amplicons for S. carnosa and 64 DNA amplicons for S. coronaria , all of which were polymorphic between the two accessions. Correlations between the molecular and physiological data revealed statistically significant correlations between the salt response of these two Sulla accessions and two molecular markers B340 and B860, in roots and shoots, respectively. S. coronaria showed greater salt tolerance on the basis of growth and K/Na selectivity, making it a good candidate for inclusion in a future breeding programme.
