Abstract

Studying the full profile of fatty acids in seed oil from 52 lines of the VNIIMK sunflower genetic collection was the goal of this work. The composition of ten fatty acids in the seed oil was analyzed using gas-liquid chromatography of fatty acid methyl esters. The content of fatty acids (%) in the seed oil was: palmitic acid on average 6.3 with a range from 3.0 to 27.7; palmitoleic 0.3 (0.03-5.4); stearic 3.9 (1.1-10.4); oleic 51.5 (14.0-91.4); linoleic 32.2 (0.8-71.1); linolenic 0.05 (0.01-0.1); arachidic 0.3 (0.1-0.6); eicosenic 0.2 (0.1-0.3); begenic 1.0 (0.4-2.2); lignoceric acid 0.3 (0.1-0.6). The coefficient of variation ranged from 27% for lignoceric acid to 59% for palmitic acid, with an average CV of 40%. Of the 45 studied pairs of connections between fatty acids, reliable correlation coefficients were established for 20 pairs of characteristics, 10 positive (from 0.917 to 0.281) and 10 negative (from -0.974 to -0.315) values. The highest positive value of the correlation coefficient was noted for the palmitic-palmitoleic acid pair, and the most negative for the oleic-linoleic acid pair. The discovered wide variation in the content of each fatty acid in the lines of the sunflower genetic collection will allow the lines to be used both in research on biochemical genetics and in practical breeding for oil quality.
