Abstract：In order to determine the effects of saline-alkaline stress on the quality of peanut fatty acids,45 peanut varieties and breeding materials were planted in the breeding field and saline-alkaline land.At the mature period,the seed samples of each variety were mixed separately,the contents of 8 kinds of fatty acids were measured using gas chromatography,and the change of each fatty acid component was studied with the principal component analysis method.The results showed that peanut acid,arachidonic acid,tetracosenoic acid,palmitic acid and stearic acid were largely influenced by saline-alkaline stress,while the main fatty acids in peanut including oleic acid and linoleic acid were less changed under saline-alkaline stress.It indicated that the effects of saline-alkaline stress on the quality of peanut fatty acids were small.
