Evaluation of nutritional and antinutritional compounds in a collection of Camelina sativa varieties

Camelina [Camelina sativa (L.) Crantz] is an emerging oilseed crop that is attracting interest because of its high environmental adaptability and oil and protein quantity and quality. Seventeen camelina varieties of different geographical origins, sown in the same locality on two sowing dates, were compared for oil, protein, and antinutritional compounds in the meal. ANOVA showed that sowing time significantly affected the content of main fatty acids, whereas 1000-seed weight, glucosinolates (GLSs), trypsin inhibitor (TI), monounsaturated and polyunsaturated fatty acids were related to the genotype. Among the varieties analyzed, Pearl and CCE26 proved to be the best source of healthy oil, with high n-3/n-6 ratio, whereas Luna and Przybrodzka, having a lower content of GLSs and TI, were suitable for animal feed. Principal Component Analysis (PCA) allowed to group the 17 varieties into three subgroups, and the largest variation was observed among the Canadian varieties.
