The sunflower oil is very important in human food because it contains a high percentage of unsaturated fatty acids. This oil ideally combines high nutritional value due to its content in linoleic acid with the high stability resistance during cooking because of oleic acid. This paper aims to show the variation of the main fatty acids in sunflower oil depending on environmental conditions and sowing date. In the studied area, adjusting the planting date and considering climatic factors, we can obtain the desired fatty acid percentage in our inbreed lines, used further for obtaining valuable hybrids. The same set of sunflower inbred lines was planted in two stages: April 10 and the May 27. In this period the environmental factors varied from low temperatures and rainfalls up to very high temperatures and severe drought, year 2012 being marked by extreme phenomen.
