Abstract :Flax insert ignore into journalissuearticles values(Linum usitatissimum L.); is an industrial plant that is used for multi-purposes in the world with its oil and fibers properties and have commercial importance. Flaxseed oil, besides being an alternative oil product, is an important additive in functional foods and animal feeds. In addition, it is rich in α-linolenic acid insert ignore into journalissuearticles values(ALA);, lignans, proteins, dietary fibers and organic acids. Owing to its significant functions, the present study was designed to investigate the fatty acid and organic acid composition of flax cultivars insert ignore into journalissuearticles values(Karakız, Milas, Beyaz Gelin, Sarı-85, Konya Kahve, Clli1392, Clli1355); under alkaline stress conditions insert ignore into journalissuearticles values(≈pH:9,70);. Accordingly, with respect to oil yield, highest yield was noted for Sarı-85 with a value of 2.28 g, whilts the lowest value insert ignore into journalissuearticles values(0.84 g); was recorded for Clli1392. Regarding oil components, in parallel to the yield, the highest percentage of α- linolenic acid was observed in Sarı-85 insert ignore into journalissuearticles values(60.51%); and the lowest value of the relevant compound was ascertained in Karakız insert ignore into journalissuearticles values(39.49%);. In relation the profile of organic acid compounds; Clli 1355 were rich in succinic acid insert ignore into journalissuearticles values(46.705 ng/ul);, lactic acid insert ignore into journalissuearticles values(35.238 ng/ul); and acetic acid insert ignore into journalissuearticles values(176.494 ng/ul);, whilst Konya Kahve and Sarı-85 were found to be rich in propionic acid, 214.232 ng/ul and butyric acid, 32.895 ng/ul, respectively. In order to reduce the dimension, correlate and visualize the assayed parameters, the relevant data of the study was subjected to principal component analysis and heat-map clustering. The clear discrimination and scattering among the cultivars corresponding to the parameters were observed.
