The purpose of the research is to assess the productivity and adaptability of Camelina sativa depending on the natural and climatic conditions of the forest-steppe zone of the Middle Volga region and the steppe Crimea. The researches were conducted in two regions (Penza and Crimea) with contrasting hydrothermal conditions in 2015–2019 years. Climate conditions in the years of researches were characterized by significant variability in both the degree of humidity and temperature regime in both regions. The hydrothermal coefficient in the Crimea varied in the range of 0.23–1.11, in the conditions of Penza - from 0.45 to 1.10. The index of environmental conditions varied from -0.58 to 1.28 units depending on the natural and climatic zone. On average, in 2015–2019, the productivity of Camelina changed from 1.45 to 1.79 t/ha in Penza and from 0.56 to 1.66 t/ha in Crimea. The highest yield of Camelina sativa was recorded in 2016 in Penza and in 2017 in the Crimea and amounted to 1.79 and 1.66 t/ha, respectively. The value of the index of environmental conditions is 1.17 and 1.28 with hydrothermal coefficient of 0.82 and 0.61, respectively. Depending on the conditions of the year and the region, the oil content varied from 33.9 to 43.9 %. At the same time, there is a tendency to decrease the amount of oil for all years of study in the direction from the Crimea to the zone of the Penza region. Camelina sativa is characterized by a high level of resistance to stressful conditions (0.49– 1.10), differs in environmental adaptability (bi=1.15–1.17), has a high fitness criterion, 41.2–41.5 g/m2, depending on the region.
