Abstract: 【Objective】 To study the effects of salt and alkali stress on the emergence rate, growth rate and yield of peanut with high oleic acid. 【Methods】 In this study, 34 varieties (lines) of peanut with high oleic acid were used as materials to record the changes of seedling emergence rate, agronomic traits and growth rate of peanut with high oleic acid planted in saline-alkali land, in order to provide data support for screening peanut varieties suitable for planting in saline-alkali land. 【Results】 Under saline-alkali stress, the seedling emergence rate of Jihua 18 was the highest, and that of Jihua 9 was the lowest. The growth rate of main stem height of flowering 910 was the fastest, and that of Kainong 1760 and P19-24 was the slowest. The growth rate of peanut decreased with the extension of growth period. At the same time, the yield of high-oleic acid peanut was significantly inhibited by salt-alkali stress. Yuhua 37, Kainong 1715 and Huayu 9130 had the highest relative yield and better salt tolerance. Different varieties (lines) had great differences in different identification indexes. 【Conclusion】 The comprehensive evaluation value of salt and alkali resistance is obtained through membership function analysis, and cluster analysis carried out. 34 materials divided into 4 categories, and the first category belongs to 1 material with high salt and alkali resistance. The second category belongs to 7 saline-alkali strong material; the third category belongs to 15 salt-resistant general materials; The fourth category belongs to 11 salt sensitive materials
