Fatty acid profiling in gobhi sarson (Brassica napus)

Abstract

An experiment was carried out during 2017-2018 to estimate fatty acids and the oil content (OC) in fifteen Brassica napus genotypes. The quality parameters of oil include fatty acids (FA) and the oil content (OC), important trait differed significantly (p?0.05) amongst the Brassica species genotype. Among the genotypes, significant differences were noted for the fatty acids and the oil content (OC). In Brassica napus seeds oil content varies in between the range of 37.45–41.86% respectively. The saturated fatty acid (SFA) includes the Palmitic acid (PA) varied in between the range of 2.68–4.43% and oleic acid (OA) content results lied between 8.88-56.18% respectively. In linoleic acid (LA) and linolenic acid (LNA), presence of significant differences (p?0.05) was there. The content of linoleic acid (LA) lies in the range between 12.97- 17.98% respectively and linolenic acid (LNA) content varied from 13.41-23.42% respectively. The stearic acid (SA) content varied from1.20-1.66 respectively. Erucic acid, another essential trait, significant differences were noted amongst the Brassica species genotypes i.e. 12.96-48.80%. The minimum erucic acid (EA) content was noted in GSL-1 genotype and the genotypes namely RSPN-28 and CNH-13-2, EC552608, GSC-6 have also low EA content and the rest of the genotypes namely, RSPN-29, DGS-1, RSPN-25, CNH-11-7, CNH-11-13, RL-1359, HNS-1101, GSC-101, CNH-11-2, HNS-1102 have high erucic content. In fatty acids (FA) content, significant differences were observed in rapeseed-mustard. Desirable cultivars with higher yield and oil content are the chief objective of this concerned study to be further employed in the breeding program.
