A genus Camelina has been attracted as a promising oil crop, especially available in drought and marginal conditions. Due to more demands on arable land for bioenergy crops, price of agricultural products has been a challengeable issue. In that respect, development of Camelina crop with higher germination rate and germination energy can be a strategy to secure seedling establishment, nutrient uptake and long vegetative period. In order to be easily available in the field and laboratory conditions, Camelina seed needs to be optimized for its germination temperature. Germination temperature regime was in a range of 8 to $32^{circ}C$ initially, and consecutively narrowed down to 8 to $20^{circ}C$. Based on the temperature range, Camelina germinated greater than 96% at $8-16^{circ}C$ in two weeks after sowing, but germination rate started to decrease at the higher than $24^{circ}C$ and was significantly low at higher than $32^{circ}C$. In terms of rapid time to reach the maximum germination rate and greater germination energy, temperature ranged from 12 to $16^{circ}C$ was found to be desirable for Camelina germination. Although germinationa rate was greater at $16^{circ}C$, lower temperature close to $12^{circ}C$ would be favored for the field conditions where greater root growth leading to healthier seedlings and better nutrient or water availability is considerably demanded.
