Responses of five wheat varieties to increasing soil salinity were determined through pot culture experiment.Subordinate function value method (SFVM) was adopted in this paper to evaluat e salt resistance of five wheat variet ies comprehensively.Relative water content (RWC), relative electrolyte leakage percentage (RELP), leaf expansion rate (LER), dry matter stress index (DMSI), relative survival percentage (RSP), spike format ion percentage stress index (SFPSI) and grain yield stress index (GYSI) were introduced as the indexes of evaluation.The results of comprehensive evaluation by means of the subordinate degree comprehensive value of growth and physiological characters and stress indexes of yield characters and their average value showed that "Zhishen No.2" and "Lumai No.19" were of the highest subordinate degree comprehensive value (∑X(u)) and the largest average value (X(u)) of these indexes among five wheat varieties under extreme soil salinity, whereas "Lumai No.23" was of the smallest.It meant that "Zhishen No.2" and "Lumai No.19" were of stronger ability of salt resistance, whereas "Lumai No.23" was of less ability relatively.The statistics also showed that there was positive correlation between the stress indexes of yield characters and subordinate degree of growth and physiological characters.
