In order to study the relationships of some morphological traits in 35 pure (doubled-haploid) lines of Camelina oilseed, an experiment was conducted in autumn cultivation in a randomized complete block design with 3 replicates. Plant height, number of pods per plant, number of seeds per pod, shoot weight and seed weight per plant were measured in three separate blocks. In addition, correlation coefficients, genetic and phenotypic correlation coefficients, heritability, genetic advance and genetic gain were estimated for the traits mentioned. The results showed that there was a significant relationship for the number of pods per plant and number of seeds per pod. line No. 9 had the highest number of seeds per plant (84.6) and line No. 15 had the highest number of seeds per pod tree (16.7). Also, grain weight had a positive and significant correlation with aerial weight. The number of seeds per plant had the highest genetic contribution
