Guizotia abyssinica (L.f.) cass.: An untapped oilseed resource for the future
چکیده انگلیسی

Amongst minor oilseed crops, niger has not been given considerable importance as compared to the sunflower, safflower, linseed and sesame. A study on 35 niger genotypes was conducted to evaluate their potential in terms of oil quantity, quality and biodiesel traits. Oil quality was determined by fatty acid composition for two consecutive years and the results were compared with other minor oilseed crops. Niger oil has four major fatty acids namely palmitic, stearic, oleic and linoleic acid. Genotypes which showed consistent fatty acid profile for the 2 consecutive years were also reported. Oleic and linoleic fatty acids showed high variability ranging from 23.52 to 53.05% and 32.03–58.28%, respectively. High oleic (IC372586) and linoleic acid (IC211078, IC211080 and IC259393) containing genotypes were also identified. Total unsaturated fatty acid (81.79–85.06%) was found to be higher than total saturated fatty acid (14.94–18.21%). Based on saponification number (200.16–202.16) and Iodine value (105.69–126.7 g I2 100 g−1) the niger oil finds its application in various industries while cetane number confirmed the use of it as biodiesel.


► High variability in oil quality.
► TUSFA higher than TSFA.
► Niger oil- a biodiesel source.
