Determine the stability of sunflower seed yield, an experiment in a randomized complete block design with 4 replications of four research stations, including Isfahan, Birjand, Sari and Karaj. Analysis of the data showed that there is considerable variation in terms of grain yield. The results showed that the coefficient of variation for grain yield Nkarmoni and Brocar cultivars are biological stability and a high degree of flexibility. Terra, Vidoc and Alisson Cultivars were stable respectively, according to the minimum variance Shukla, among varieties for grain yield. Based on the regression coefficient Fabiola and Arena Cultivars were average yield stability and adaptation Suitable. According to the graph AMMI1 of the function and stability Nkarmoni was higher than the other varieties. AMMI2 figures in the chart Euroflor, Alisson, Mas96a and Fabiola in Birjand place were identified yield stable part numbers and locations. GGE biplot method on grain yield was studied areas were divided into mega- environments, First mega- environments were included Isfahan and Sari places and second mega- environments were Birjand and Karaj places in terms of yield, Isfahan, Karaj and Birjand were varieties best.
