Conteúdo: 	The objectives of this study were to determine the genetics of plant height from selected crosses in sunflower (Helianthus annuus L.). An incomplete diallel analysis involving inbreds Advance 946, HA 89 and Guayacan (S4) was conducted to determine genetic effects. Epistatic genetic effects were significant for all crosses. Additive x additive interaction was the most important epistatic genetic effect for plant height. Additive effects were more important than dominance effects. Heterosis was observed for plant height, number of leaves per plant and internode lenght. Correlation between plant height and number of leaves was high (r= 0.8) while that between plant height and internode length was medium (r=0.6).
