Abstract: The development of the pods and seeds and the accumulation pattern of fatty acids during the development of peanut seeds were studied with Luhua14. Results showed that thirty-nine days after the gynophore into soil, the small seeds away from the fruit needle was longer than the big seeds near the gynophore. Near maturity, the average weight of the small seeds exceeded that of the big seeds. There were twelve different fatty acids in peanut seeds: oleic acid, linoleic acid, cetylic acid, stearic acid, docosanoic acid, arachic acid, tetroacosanic acid, arachnidoic acid, vaccenic acid, linolenic acid, palmitoleic acid, myristic acid. Along with the development of the seeds, the content of total fatty acids and oleic acid increased gradually, whereas linoleic acid decreasd slowly. Oleic acid and linoleic acid accounted for 79. 4% near maturity. The ratio of oleic acid and linoleic acid was increasing along with the maturaty of peanut seeds.
