Abstract: Okra（Abelmoschus esculentus L.） is an important horticultural crop. Screening and identification of salt tolerant germplasm resources under seawater stress could lay a foundation for cultivating new salt tolerant okra varieties. In this study, 100 okra germplasm resources from different geographical sources were treated with seawater of 50% concentrations. Seedling height, leaf length, leaf width, petiole length, stem diameter and chlorophyll content were measured. The salt tolerance of okra germplasm resources under seawater stress was comprehensively evaluated by fuzzy comprehensive evaluation method. The results showed that seawater stress had a great effect on seedling height, but had a relatively small effect on leaf width and stem diameter. OG 36, OG 60, OG 11 and OG 10 were highly salt tolerant varieties, and OG 70, OG 87 and OG 13 were salt sensitive varieties. The membership function value of seedling height had a high correlation coefficient with the total membership function value, which could be used as an important index for the screening of salt tolerance of okra under seawater stress.
