Generation mean analysis of eight quantitative traits: days to 50 percent flowering, plant height, stem diameter, head diameter, percent seed set, seed yield/plant, 100 seed weight and oil content in sunflower revealed that all are predominantly under the control of dominant gene effect. Also, digenic epistatic genetic effect were also found to be important in the inheritance of these traits. Therefore, appropriate breeding methods such as reciprocal recurrent selection and biparental mating methods would be needed to improve these traits.
