An experiment was conducted during 2014-2015 to study the oil and fatty acids content in 26 genotypes of Brassica species. Significant differences (p≤0.05) were observed among the genotypes for the oil quality, viz. oil content and fatty acids content. Oil content is in the range of 32.67–39.47%, 37.82–40.56% and 40.35–41.43% in Brassica juncea, Brassica napus and Brassica rapa seeds, respectively. The saturated fatty acid (Palmitic acid) content is in the range of 3.08–3.85, 3.70–5.15, 2.75–3.73% in Brassica juncea, Brassica napus and Brassica rapa, respectively and oleic acid content is in the range of 0.80–48.70, 16.15–37.98 and 6.21–16.15 in Brassica juncea, Brassica napus and Brassica rapa, respectively. Significant variation (p≤0.05) was also observed for Linoleic acid content and linolenic acid. Linoleic acid content varied from 11.00- 45.30, 18.57- 26.93 and 14.08- 18.18% in Brassica juncea, Brassica napus and Brassica rapa, respectively and linolenic acid content varied from 11.10- 26.72, 9.99- 17.23 and 9.82- 26.66% in Brassica juncea, Brassica napus and Brassica rapa, respectively. The Erucic acid, another important trait also differed significantly amongst the Brassica species genotypes being 0.80- 49.40, 10.04- 34.96 and 43.77- 49.99%. The minimum Erucic acid content was recorded in Brassica juncea genotypes PM-24 (0.80%) and significantly at par with PM-21, PM-22, Pusa Karishma and Nov Gold, whereas maximum Erucic acid content were recorded in Pusa Bold (49.40%), DGS-1(34.96%) and RSPT-02 (49.99%) in Brassica juncea, Brassica napus and Brassica rapa, respectively. Significant variability in fatty acids content were noted in rapeseed mustard. The present study can be utilized in the breeding programme to develop qualitative genotypes with higher oil content and yield potential.
