Abstract

Abstract: The genetic improvement of tomato tolerance to drought and salt stress was reviewed in this paper. The contents mainly included the potential wild tomato species for drought and salt tolerance and the evolution，QTL exploration，the genetic and stacking effects of the identified QTLs，and the genetic engineering with exogenous genes，including ion transport and compartmentalization，osmotic regulation，antioxidant protection，transcription factor，stress related proteins，for tomato genetic improvement with drought and/or salt tolerance. Meanwhile，the present problems and future strategies，mainly including phenotype determination of drought and salt tolerance in tomato，genome wide association study（GWAS），genetic engineering，cross-talking，small RNA and epigenetics，were also discussed.

Key words: tomato, abiotic stress, salt tolerance, drought tolerance, genetic improvement
