Abstract

The seed oil samples of 52 mustard genotypes belonging to six species of mustard (Brassica spp.) Brassica juncea (31 genotypes), B. rapa (6 genotypes) , B. napus (2 genotypes), B. nigra (6 genotypes), B. arvensis (10 genotypes) and B. alba  (2 genotypes) collected from USA gene bank and diverse ecologies of Turkey were used as research material and evaluated for their fatty acid composition by gas-liquid chromatography (GLC). The results showed significant variability among all genotypes for fatty acid composition. Erusic acid (C22:1; 20.63-47.87%), oleic acid (C18:1; 7.42-24.54%) and linoleic acid (C18:2; 9.61-25.11%) were determined to be the dominant fatty acids among all cultivars. It has been observed that the results in wild mustards have too many resemblances with the composition of fatty acid of mustard which is used by people in alternative medical science, paint, food industry and biodisel production. The great variability in seed oil contents in Brassica genotypes showed their potential for use in future breeding programs.
