Recent interest in renewable energy sources and the need to diversify cropping systems have triggered research interest in camelina (Camelina sativa L. Crantz). Camelina is well adapted to the temperate dryland climates and can be used as an energy crop. But information on agronomic evaluation of camelina cultivars for biodiesel feedstock are limited. The objective of this study was to evaluate six spring camelina cultivars (cv. Blaine Creek, Calena, Ligena, Pronghorn, Shoshone, and Suneson) on seed yield, oil concentration, and oil yield. The study was carried out from 2013 to 2015 at three locations (Havre, Moccasin, and Pendroy, MT). Over locations and years, mean seed yield differences among cultivars were significant (P < 0.05). The mean seed yield for cultivars ranging from 1295 kg ha⁻¹ (Suneson) to 1420 kg ha⁻¹ (Ligena). Ligena and Calena showed a combination of good seed yield performance and stability across environments. Environmental means for seed yield differences were substantial compared with cultivar means. The location Havre produced 45 and 32% more mean seed yield than Pendroy and Moccasin, respectively. There was no significant difference among cultivars in oil concentration and oil yield. The absence of variations in oil concentration and oil yield differences among these cultivars could indicate the need for further research to improve these qualities essential for biodiesel.
