Sunflower (Helianthus annuus L.) is one of the most important oil crops in world and mostly produces oil. Due to global warming unexpected climatic changes especially extreme heat droughts recent years, as a spring crop sunflower affects severely by these conditions vegetation period loses seed yield hardly. Plant breeding longer process taking at least ten years develop cultivars. Therefore, breeders should consider future conditions, hence it seems that drought tolerance primarily their programs. Oil content trait than major goal studies; likewise, affected from conditions. The study was conducted determine contents some inbred lines hybrids developed lately National Project conducting Trakya Agriculture Research Institute (TARI). Based on results; significant relationships were observed between other traits male exhibited more variability female changed 13.16%–54.05% 19.12%–52.46% lines, 30.17%–53.68% hybrids. While negatively thousand weight head diameter, leaf number, area, followed this trait, respectively. path analysis for contribution determining content; determined directly then negative way, determination stress over two traits. yield, reduced about 90% lines. Severe resulted heavy decreases well so no need focus increasing 40%–43% be sacrified kind hybrid evaluations three different locations mentioned weight, area number are affecting positively Practical applications commonly influenced environmental such hot temperatures being growing crop. These stresses appear during mid-summer suffers stressess resulting losses with lower content. Especially grain filling results season. better stress. Furthermore, also characteristics consisting sunflower. we have developing higher instead because sacrifice give
