Fatty Acid Composition in Seeds of Jack-bean [Canavalia ensiformis (L.) DC] and Sword-bean [Canavalia gladiata J&cq.) DC] Germplasm from South India: A DIVA-GIS Analysis

摘要

Twenty one accessions of germplasm of Canavalia (C. ensiformis-ii; C. gladiata-9), a wild edible legume collected from Andhra Pradesh, Kerala and Tamil Nadu in South India were analyzed for oil content and fatty acid composition. The oil content in Canavalia ranged between 0.4-2.3%. The variability for oil content and fatty acid composition is presented in this paper. Seed lipids of all Canavalia accessions contained higher amounts of unsaturated fatty acids (69.1-81.8%) compared to saturated fatty acids (18.2-30.9%). Oleic acid was found to be the major component in all the seed lipids. Grid maps were generated using DIVA-GIS for the analysis of diversity based on total unsaturated fatty acids and total saturated fatty acids. IC310951, a C. ensiformis accession collected from Andhra Pradesh recorded the highest omega-3 fatty acid (linolenic acid, 11.4%) which forms an essential fatty acid.
