The plant Camelina sativa (L.), a member of the Brassicaceae family, is an ancient oilseed crop. Due to its adaptation to vast areas of the world and its unique oil composition and properties, it is useful for the production of biofuels, jet fuel, bio-based products, feed, and food. The present study was performed to investigate the morphological and agro-physiological characteristics of this plant through Factor Analysis (FA). For this purpose, 136 doubled haploid line genotypes were assessed in the form of a randomized complete block design with three replications in the research field of Razi University, Kermanshah, Iran. FA, based on the principal component analysis method and varimax rotation, showed that two important factors make up about 74.97% of the total variety of characters. The Eigen values of these two factors were 9.76 and 3.72, respectively. The first and second factors assigned 53.99 and 20.98 percent, respectively, of the total variation. Factor 1, which was called the biological performance, included the seed yield, number of pods per plant, number of pods per main branch plant, number of pods per lateral branch, biological yield per five plants, plant height with roots, root weight, shoots weight, pod straw weight, number of lateral branches, length of lateral branch and length of the main branch. Factor 2, which was called the seed characteristics, covered seed length, seed perimeter, seed area, the weight of 1000 seeds, and the number of seeds in the pod. Using FA, two sets of traits were identified and named in Camelina. The traits in one category that affected the attributes of the other category were selected to be studied to help Camelina breed more precisely. Entering more traits and performing FA increased the accuracy of the categories.
