Abstract
Crosses were made between a salt tolerant wild tomato [Lycopersicon cheesmanii ssp. minor (Hook) C. H. Mull.] and a domestic cultivar (L. esculentum Mill. cv. Walter). Selections were made from resulting progenies for salinity tolerance at germination, seedling establishment, and the reproductive stage of their life cycle. The selected progenies were tested for survival and fruit production in salinized solution culture experiments, and in field greenhouse trials where they were irrigated with various dilutions of seawater applied to sand. Salt tolerance was shown to be a heritable trait. Plants selected from the F2 and successive backcrosses to ‘Walter’ survived and produced fruit when irrigated with up to 70% seawater in the sandy soil culture trials, whereas ‘Walter’ did not survive.
