The longitudinal gradient of oleic acid content in different parts of sunflower seeds

The results of the research on variability of oleic acid content in different parts of a seed of inbred lines of sunflower genetic collection at VNIIMK are presented. The mid oleic line LG27 had the highest increase of oleic acid content from gemmule to the distal end of cotyledon, about 13.1 %, the increased oleic line VK678 had 12.8 % and the low oleic line LG28 had 5.5 %. The high oleic line LG26 did not show any differences in investigated character between the seed parts.
