Abstract
In order to study whether salt tolerance at the initial growth stage is conferred at the adult stage and to evaluate the estimates of genetic variability parameters, heritability and genetic advance, three tolerant (CLN2498A, BL1176 and CLN1621 L) and two non-tolerant (17902 and L02875) tomato genotypes, selected at the initial growth stage were tested for both absolute and relative values of growth at three levels of NaCl (control, 10dS per m and 15dS per m) for various flowering and maturity parameters. Significant differences were found for all the traits such as plant height, number of trusses/plant, number of flowers/truss, fruit length, fruit width, average fruit weight, Na+ concentration, K+ concentration and K+/Na+ ratio. It was observed that salinity caused reduction in all the yield components of tomato genotypes but least reduction was noted in CLN2498A, BL1176 and CLN1621 L. High heritability estimates for plant height and K+ concentration coupled with high genetic advance in both low (10dS per m) and high (15dS per m) salinities suggested a potential for genetic improvement through breeding and selection.
