Abstract Salt stress is one of the main abiotic stresses affecting cucumber growth and development．It
is of important significance to carry out studies on cucumber tolerance for salt stress and cultivate salt tolerant
varieties for improving cucumber salt tolerance and increasing use ratio of saline-alkali land．This paper
reviewed the following 4 aspects：evaluation of salt tolerance in cucumber germplasm resources；effects of
salt stress on cucumber growth，development and physiology；genetic analysis and genes mining related to
cucumber salt tolerance and major measures for improving cucumber tolerance to salt stress，etc．Emphasis
was laid on research progress made in cucumber breeding for tolerance to salt stress in recent years．At the
same time，the paper put forward the problems existing in current research on cucumber breeding for tolerance
to salt stress，and prospected the research directions in future．
