70% of the decline in agricultural production is caused by abiotic stress factors, such as than drought and variations in precipitation. Its factors can pose problems in terms of starting the small- seeded species in the early stages of vegetation (germination) and crop informing in plant growth. Camelina (Camelina sativa L. Crantz, Brassicaceae) is an important low -yield oilseed crop consumption of inputs. Camelina East considered as small- seeded species, this setting can directly influence seedling germination, growth and development. The current research East based on the study of germination and growth of sevens varieties of camelina. Germination tests have summer conducted at the laboratory level, and growth tests have summer posed on the ground according to a completely randomized block experimental design with three repetitions. The results revealed significant differences (p < 0.05) between the different seven varieties for germination capacity, emergence, number of plants in rosette and precocity. Variety 7 is the best performing variety for the parameters studied: it has excellent germination capacity (98.66%), it produces 7 plants per 31 square centimeters, 10 rosette plants per 31 square centimeters and it is the earliest with duration of 48 days from sowing to 50% flowering.
