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.

**2 Results and Discussion**

Table 1 Combined analysis of variance sunflower cultivars studied in 4 locations Note: **, *, Ns, respectively, indicating no significant difference statistically significant at the 5 and 1 percent level |

**2.1 Results are based on analysis of variance methods**

*i*) showed that the number of Brocar and Nkarmoni cultivars of the lowest coefficient of variation was accounted for. The biological stability and the flexibility are high. Azargol and Nkarmoni cultivars are stable in research based on Francis and Kannenberg’s (Francis and Kannenberg, 1978) figures. The Arena and Pomar cultivars, respectively, with the highest coefficient of variation and the expression showed the lowest stability.

**2.2 Stability analysis of genotypes based on regression analysis**

*D*lower the deviation is less stable and more sustainable cultivars, The Terra and Pomar genotypes were stable with the lowest varieties. And according to the average performance Alisson and Fabiola genotypes can be introduced as stable genotypes. By definition, Euroflor and Almanzor genotypes were introduced unstable genotypes in these models (Table 3).
