Between 2005 and 2006 in the Maize Research Institute- Knezha are investigated the manifestation of heterosis and the degrees of dominance in F1 and F2 of the hybrids Kn 689B, Kn 611, Kn 613, Kn 625, Kn 683A based on the traits: plant high, length of the ear and number of seeds per ear. It is established that the inheritance of the traits occurs in a clearly expressed positive heterosis and depression. There is certain variationb depending on the year of growing. Analyze pf the degrees of dominations in F1 and F2 based on the investigated traits shows that the manifestations of heterosis is due to overdominance, epistasis and dominance of the respective conditions of growing.
