Abstract

   In order to determine the stability of oil percentage of sunflower cultivars, a randomized complete block design with four replications was conducted in four research stations in Isfahan, Birjand, Sari and Karaj. Combined variance analysis showed that there was considerable variation among the cultivars in terms of oil percentage. The coefficient of variation for oil percentage of Azargol and Vidoc had the lowest coefficient of variation, respectively. Fabiola, Euroflor, and Altesse cultivars were genotypes based on the Francis and Kannenberg method for oil percentage traits. Based on the results obtained from the Shukla stability variance, Brocar, Alisson and Fabiola cultivars were among the stable genotypes for oil percentage, respectively. Based on the regression coefficient, Brocar and Fabiola cultivars had a good overall consistency in terms of oil percentage. According to the AMMI1 chart, the oil content of Joana and Nkarmoni were more stable and more stable. In the AMMI2 chart, Pomar, Fabiola, Arena and Brocar and Birjand locations were recognized as the most stable cultivars and locations for oil percentage. In the GGE bi-plot method, the locations were divided into two mega environments, the first mega environment of Isfahan, Karaj, and Birjand locations and the second mega environment including Sari. In terms of this trait, in the first cloud of the first Fabiola variety, and in the second medium, the Almanzor cultivar was the best cultivar.
