There are presented data on heterosis displaying at the experimental hybrids F1 of winter rapeseed (Brassica napus L.) by the basic economically valuable traits. The research was conducted in the central zone of the Krasnodar region. We determined a level of phenotypic dominance and heterosis effect in some winter rapeseed hybrids. In preliminary test, a hybrid combination 39712 × ОRK 9 demonstrated authentically high true and competitive heterosis and overdominance by all the studied traits.
