Evaluation of Salinity Tolerance of Eggplant Germplasm under Greenhouse Conditions

Abstract

Purple eggplant germplasms collected by the Tropical Vegetable Research Center, Kasetsart University were evaluated. There were 20 germplasm accessions and 4 commercial varieties at different salinity levels,
as 2 dS·m^-1 (no salt), 4 dS·m^-1 and 6 dS·m^-1. All accessions could be grown at all salinity levels. Seven accessions, including KM, KK, SM-267, SM-298, SM-065, SM-244 and SM-131 showed fruit setting at all salinity levels and the accessions SM-172, SM-570, SM-371, SM-603 and SM-232 could be produced fruit at 4 dS·m^-1. The morphology traits were evaluated as flower color and fruit shape. The flower were two colors: leg color that were purple and white. There were five fruit shapes; flatten, long, round, narrow-long and ovate. We could select eggplant for saline soil tolerance in eggplant breeding program.
