Abstract: In this study, 59 confectionary sunflower varieties（lines） as the test materials, planting in a saline-alkali land in Longsheng town, Dengkou county, Bayannaoer, Inner Mongolia, the experiment land belongs to typical saline alkali soil in Hetao irrigation area. The growth period of record, determination of the agronomic traits, the yield per unit area and the determination of quality traits of grain harvest were measured.Using factor analysis and cluster analysis of 59 confectionary sunflower varieties with SPASS19.0 analysis software,comprehensive evaluation of salt and alkali resistance was done. The results showed that the difference salt resistance ability of different confectionary sunflower varieties were larger; the saline resistance of 59 confectionary sunflower were divided into 3 groups by clustering analysis. The varieties whose saline resistance were strongest were 30.5%,those whose saline resistance were stronger were 42.4% and those whose saline resistance were weakest were27.1%.Then factor analysis showed that the strongest salinity tolerance varieties were 14CF56 and 14CF57 and the weakest salinity tolerance varieties were 14CF44 and 14CF51.
