Abstract：The seeds of 50 wheat varieties with different salt-tolerance were taken as experimental materials.They were used for water culture with 1.3% NaCl to investigate their salt-tolerance during germination and seedling stages.The germination rate, plant height and root length on the 8th day were measured and analyzed to evaluate the salt-tolerance differences of the 50 wheat cultivars.The results showed that five first-grade salt-tolerant varieties (Yannong 5158, Lumai 21, Yannong 19, Yannong 0428 and Shannong Purple Wheat 1), fourteen second-grade salt-resistant varieties and four salt-sensitive varieties (Shi H68-366, Tengmai 3, Bima 4 and Tainong 18) were screened out.Through cluster analysis based on the salt-tolerant membership function value of 50 wheat germplasm materials, they were divided into five categories.This research could provide certain theoretical supports for salt-resistant breeding in wheat.
