Abstract: Fifty-nine peanut varieties were selected and planted in Wuhan, Shijiazhuang, Puyang and Zhoukou in 2016-2017. The content of resveratrol in peanut seeds was detected by high performance liquid chromatography ( HPLC) after harvest. The results showed that the content of resveratrol in peanut varieties was significantly different between varieties and environment. The average content of resveratrol in Wuhan was relatively higher than that of other sites. Based on the comprehensive analysis of the detection results of planting in 4 areas in 2 years, two materials with high and stable resveratrol content under multiple environments were selected ( Jihua 2 and Jihua 13). The correlation analysis of oil content and fatty acid test results of these varieties showed that there was no significant correlation between resveratrol content of peanut seed and oil content or 8 main fatty acids. The results provided a theoretical basis for cultivating peanut varieties with high resveratrol, high oil and excellent fatty acid composition.

Key words: peanut varieties, resveratrol content, oil content, fatty acid
