The inheritance of sunflower flowers color has been investigated in inbred lines collection of Yurjev Plant Production Institute. It has been shown, that in F₁ occurs yellow color only being most found among all the types of flowers coloration. The 3 : 1 and 9 : 3 : 4 types of segregation ratios have been revealed in F₂ that is indicative of difference parents by one and two genes, respectively. Studies of the inheritance of branching and male fertility restoration have indicated a monogenic control of these traits in investigated inbred lines. It is established that all genes controlling the studied traits were independently inherited.
