Evaluation of Different Flax Cultivars in Their Oil, Fatty Acids Protein andAmino Acids and Correlations

Abstract

This study was carried out in the Faculty of Meteorology, Environment and Arid Land Agriculture, King Abdulaziz University to evaluate 7 flax genotypes from different geographical regions concerning their composition from oil and protein contents, fatty acids and amino acids, besides, calculate the correlation coefficients between the fatty acids and also between the amino acids.The main results showed that Verum cv. had the highest oil content and linolenic acid (Omega-3) while Hiera cv. was the highest in meal protein content and most amino acids. The highest amino acid concentration was proline and it ranged from 27.15% to 30.21%. Linolenic acid (Omega-3) negatively and significantly correlated with Oleic and Linoleic (Omega-6) fatty acids. Lysine amino acid positively and significantly correlated with the amino acids of Glutamine, Aspartic, Leucine, Serine and Isoleucine.
