The medicinal-oil plant Camelina sativa L. belongs to the Brassicaceae family. Various experiments have shown that the plant has much fewer water requirements and more resistance to spring cold than other oilseeds, especially Rapeseed. In this study, 136 camelina double haploid lines from anther culture progeny (F1) of crosses of 27 selected parents from different countries were generated. After ensuring that the lines were double haploid, biochemical markers were used to investigate genetic diversity. In the biochemical markers section, grain oil content, grain protein and type of fatty acids were measured. The experiment was carried out based on a randomized complete block design with four replications. To determine fatty acids using chromatography, 18 types of fatty acids were identified in camelina seed oil. Genetic parameters including phenotypic and genotypic variation coefficients, heritability and genetic advance were estimated. In this study, the highest phenotypic and genotypic variation in fatty acids (C14:0-C16:1) were estimated. Also, the highest general heritability for fatty acids (96.49% for C20:0, 98.92% for C20:2 and 98.59% for C20:3) were assessed. In this reserach, two lines with values of 35.81-36.67% linolenic acid and four lines with values between 22.08-23% of linoleic acid were identified. Also, the ratio of omega 6 to omega 3 ranged between 0.479 0 and 0.759.
