Abstract:

Peanut is an important oil crop, and its fatty acids contents were not stable due to different environments grown. In this study, 60 peanut varieties including six accessions with high oleic acid and 54 accessions with normal oleic acid widely grown in Huanghuai and Yangtze river areas were planted in four ecological regions of Wuhan, Shijiazhuang, Puyang, and Zhoukou in 2016-2017. After harvesting, the dried mature seeds were tested for fatty acid content according to the method in GB/T 5510-2011. The content of oleic acid in peanut varieties with high oleic was more stable than that with normal oleic acid. However, the contents of palmitic and linoleic acids were more stable in normal oleic acid varieties than in high oleic acid cultivars. Regarding the effect of environment grown on the fatty acids, the content of oleic acid of cultivars grown in Wuhan was higher than that grown in other regions in the present study, with the average of 52.93% and 52.64% in the two years. Comparing the fatty acid composition between high oleic varieties and normal oleic varieties, the arachidonic acid content was significantly increased by 54.10%, besides the significant increase of oleic acid content in high oleic varieties. However, the palmitic and linoleic acids were much less in high oleic varieties than in normal oleic varieties, reduced by 45.20% and 90.44% respectively. Combined with the diversity of the 60 varieties by SSR technique previously, the six high oleic acid varieties should be in different groups (G1, G2c, and G2e), showing considerable large genetic variations. These results from the present study provide a basis for the reasonable planting layout and further genetic improvement of peanut varieties.

Key words: cultivated peanut, fatty acid, oleic acid, stability
