[Free Full Text (pdf)]
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.
