we are working on improving salinity tolerance in various crops including tomato plant using various strategies. i know that ,there are some tomato cultivars produced by gene over expression to tolerate salinity.are there any cultivar grown commercially.
One of the strategies that can be adopted is irrigation method. There are many researches indicated that using sub-surface irrigation increases the ability of Tomato to tolerate salinity .Please refer to the following paper:

Salinity tolerance may be increased by exogenous application of proline. As proline is now an established amino acid which confers salt tolerance in different cereals like rice, wheat, maize etc.
According to the research work by me on drought tolerant tomato varieties..Tomato cultivar 326 (Indian tomato variety)was observed morphological and physiologically adapted for drought condition.
As far as I know, there is no commercial salt tolerant variety available across the globe.
A few salt tolerant cultivars cited in literate are of rice, wheat. Though a number of reports are available in research articles, but no-one is available at a commercial scale. Or tested on field scale. Farmers are using cultivars based on their own experiences and benefits.
