We studied 25 samples of false flax (Camelina sativa (L.) Crantz.) from the collection of the All-Russian Institute of Plant Genetic Resources (VIR). The study was conducted in the conditions of Astrakhan region in 2016-2017. As a result of the research, we selected 13 samples of false flax with seed yield of 1.0-1.9 t per ha in 2016, 10 samples with yield of 1.0-1.4 t per ha in 2017. The samples possess high biological yield also have the high coefficient of adaptability: 1.03-1.96 in 2016 and 1.1-1.6 in 2017. There was a significant variability in the system of correlations of traits over the years of the research. The correlation structure of variability in 2017 was significantly different from that one in 2016. The number of reliable correlations in 2016 was significantly lower than in 2017. In the factor structure of the economically valuable traits variability in 2016 three factors were identified covering a total of 88.8 % of the variability of the complex of traits. In the factor structure of variation in 2017, three factors were also identified, covering 77.1 % of the variability of the complex. Changes in climatic conditions during the false flax vegetative period effect formation of the main economically valuable traits.
