Abstract
The inheritance of length and width of flag and subflag leaves was studied in two S12 generation inbred lines of winter rye (Secale cereale L). The lines (L176 and L260) showed extremally different values of the investigated leaf characters. Segregation was analysed in the F1, F2 generations and in back-cross progeny of hybrids between the lines. In comparison to the parental forms, the length and width of the flag and subflag leaves in the F1 generation was intermediate. The F2 segregation indicated determination of the character by three genes with additive effect. The width of the flag and subflag leaves was determined by two additive genes. Size of the flag leaf was positively correlated with that of the subflag one.
