Abstract: 【Objective】 The difference of yield formation and quality among different peanut varieties were studied, and the excellent high oleic acid peanut varieties suitable for planting in northern Xinjiang were selected. 【Methods】 In this study,five high oleic acid peanut varieties in which the differences in seedling yield, agronomic traits, single plant dry material accumulation, yield and quality of each variety were analyzed. 【Results】 Huayu 655 reached 21.33, the full fruit rate was 1, and the highest grain fat content was 43.35%; Huayu 917 has the highest stem height of 27.80 cm, the highest length of the first opposite branch of 22.47cm, the highest number of branches of 7.33, and the highest dry material accumulation in each period, fruit weight 172.49 g, hundred kernel weight 92.41g, yield 4,644.04 kg/hm², and O/L value of 9.30; Huayu 951 had the highest protein and oleic acid content, 26.71% and 80.05%, respectively; Huayu 956 had the highest emergence rate, To 82.75%.In conclusion, the flower breeding 917 has the highest yield and the best quality among the tested varieties. 【Conclusion】 Huayu 917 is a high oleic acid peanut variety more suitable for planting in northern Xinjiang.
