Evaluation of agronomic and biochemical traits of doubled haploid Camelina (Camelina sativa) lines under rainfed conditions

Background and Aim: Camelina [Camelina sativa (L.) Crantz], is an ancient annual oilseed crop belongs to Brassicaceae family that has also some other names including, linseed dodder, false flax or gold-of-pleasure. Ability to adapt to a vast range of environments and also its unique oil composition are two unique features of Camelina in comparison to main oil crops.Methods: In this research, ۱۳۴ pure double-haploid camelina lines were evaluated using an Augment experiment compared to “Soheil” cultivar in terms of agronomic and biochemical traits under rainfed conditions. Seeds of each pure line were sown in an experimental unit in four rows of one meter on November ۲۲, ۲۰۱۸ at the Dryland Agricultural Research sub-Institute, Sararood, Kermanshah, Iran.Results: The results of variance analysis for morphological and phenological traits showed significant differences between the lines for all the studied traits. The highest grain yield (more than one ton per hectare) was obtained from lines ۸۲, ۱۰۰, ۷۲ and “Soheil” cultivars with ۱۲۹.۵, ۱۱۰, ۱۰۶ and ۱۰۱ g.m-۲, respectively.Conclusion: The highest grain oil and protein contents were observed in lines ۴۵ and ۱۳۳ with ۳۹.۲۸ and ۳۱.۳۱ percent. Lines ۹۷ and ۹۸ had the lowest values for these traits. The mean oil and protein contents of all lines were ۳۶.۵۷ and ۲۸.۵۳ percent, respectively.
