Oil content and fatty acid composition of promising Indian Brassica campestris L. (Toria) genotypes.

Seeds of sixty four genotypes of Brassica campestris L. (Toria) were analyzed for oil content and fatty acid composition. Oil content varied from 38.9% to 44.6%. Major fatty acids viz. oleic, linoleic, linolenic, eicosenoic and erucic acids exhibited ranges from 10.1% to 17.3%, 5.9% to 14.5%, 5.2% to 15.0%, 7.7% to 13.7% and 39.6% to 59.9%, respectively. Compared to the standard cultivar ITSA, four genotypes contained 5 to 8% lower content of erucic acid; and six genotypes contained significantly higher content of linoleic acid. Oil was positively correlated with erucic acid. The observed inverse relationship between linoleic and erucic acid contents might be utilized in breeding nutritionally better Toria cultivars with both high linoleic and low erucic acid contents.
