Abstract：Peanut is one of the important oil crops and economic crops in China,but the research on the genetic stability related to environmental changes is rare.In this study,the oil content,protein content and other characters of 61 peanut cultivars planted for three consecutive years were determined and analyzed,and the genetic stability of each character was evaluated using coefficient of variation (CV).The results showed that the content of peanut oil in different years was slightly different.The CV of different fatty acid components showed larger differences,the CV of lignoceric acid,behenic acid,palmitic acid and oil content were smaller,but the CV of O/L ratio was larger,which reflected that the environmental changes could influence peanut fatty acid synthesis.We also analyzed the CV of protein and eight amino acids,the results showed that the CV of protein,lysine,proline and threonine were larger,which reflected their sensibility to environmental changes.The environmental factors had different effects on the quality traits of different peanut varieties,the characters of Yueyou 92 and Zhonghua 5 was more stability with lower CV value,whereas the CV of characters of Qinghua 5 and Jihua 4 were larger,which indicated their sensibility to environmental changes.
