Biochemical studies in Indian mustard (Brassica juncea L.) czern and coss for fatty acid profiling

Abstract

An experiment was conducted at Research farm of RVSKVV, Gwalior during 2016-2017 to study the fatty acid contents in 188 genotypes of Brassica juncea. Significant differences were observed among the genotypes for fatty acids contents. Palmitic acid content is in the range of 3.94-13.27%. The minimum palmitic acid content was recorded in MRNJ-21 and significantly at par with MRNJ-22, Rohini, MRNJ-30, MRNJ-28 and MRNJ-18 whereas maximum palmitic acid content were recorded in IDM-67 followed by ISC-12, PM28, ISC-17, L-4 and MRNJ-122. Oleic acid content is in the range of 6.07-37.10%. The minimum oleic acid content was recorded in RVM-1 followed by Maya, MRNJ-12, MRNJ-16, RVM2 and MRNJ-23, whereas maximum oleic acid content were recorded in ISC-18 and significantly at par with MRNJ-30, MRNJ-25, PM30, Karishma and PM24. Significant variation was also observed for linoleic acid content and linolenic acid. Linoleic acid content varied from 14.97-37.34 % and linolenic acid content varied from 8.29-16.75%. The erucic acid, another important trait also differed from 0.93-51.44 %. The minimum erucic acid content was recorded in PM-29 (0.93%) and significantly at par with PM25, PM21, PM30, PM22 and PM28, whereas maximum erucic acid content was recorded in Maya (51.44%), JM-1, RVM-2, IDM-41, IDM-25 and RH790. Significant variability in fatty acid contents were noted in Indian mustard.
