Peanut is a field crop with high economic benefits. In order to comprehensively utilize the nutritive value of peanut stalk and kernels to improve economic benefits，we carried out a study using 26 peanut varieties. We analyzed crude protein，crude fat，crude fiber，crude ash，calcium，phosphorus，neutral detergent fiber，and acid detergent fiber in the stalk. SPSS software was used to evaluate the nutritional value by principal component analysis. On the other hand，the nutritional indexes of fat，protein，oleic acid and linoleic acid were determined by near infrared analyzer while Topsis method was used to comprehensively analyze and rank the analysis results. The results showed that there were significant differences in the nutrient components of stalk among different peanut varieties. Shanghua 26，Ji 545，Ji 5059，Yuanza 9102 and Yuhua 90 have a higher comprehensive nutritional value. There were no significant differences in protein and fat contents among the most of peanut varieties，while there were significant differences in oleic acid and linoleic acid contents.Yuhua102 has the highest protein content，Ji5059 has the highest fat content，Jinong G99 has the highest oleic acid content and lowest linoleic acid content. If the nutrient content of stalk and kernels are taken into account，the comprehensive value of 10 varieties from the highest to the lowest is as the following order：Jinong G99， Kainong 310，Shanghua 26，Yuhua 93，Yuanza 9102，Ji545，Puhua 56，Puhua 52，Yuhua 89 and Zhengnonghua 19. These peanuts can be used as the first choice for the dual-purpose.
