DETERMINING OIL AND FATTY ACID PROFILES OF SELECTED SOYBEAN CULTIVARS UNDER SECOND CROP CONDITION IN EAST MEDITERRANEAN AGROECOLOGY

This study's objective was to analyse the oil contents and composition of fatty acids (linolenic, stearic, oleic, palmitic and linoleic acids) of 20 distinct soybean (Glycine max L. Merrill) cultivars cultivated as the second crop in Cukurova Delta in the Mediterranean region of Turkiye. Soybean cultivars Ilksoy, Traksoy maturity group II (MG: II), Atakisi, Arısoy, Cinsoy, Atem-7, Sa 88, Altınay, Asya, Bravo, Gapsoy, Kocatürk, Mitchell, Samsoy, Kristal, Umut-2002 (MG: III), Adasoy, ANP 2018, Nazlıcan, Lider (MG:3.8) were used. Field tests of this study were carried out in a randomized complete block design with three replications at the Eastern Mediterranean Agricultural Research Institute's Dogankent-Adana location in 2020-2021. Years, genotypes, and year x genotype interactions were all determined as significant in the variance analysis of the experiment's data. The fatty acid content of soybean cultivars varied between 10.00 and 12.64% for palmitic acid, 4.15 and 5.17% for stearic acid, 25.75 and 33.90% for oleic acid, 43.22 and 51.59% for linoleic acid, and 4.85 and 5.98% for linolenic acid, according to a 2-years average. Soybean cultivars' oil content ranged from 23.12 to 24.78 percent.
