Abstract:
As the result of 10 years breeding with the species Dianthus caryophyllus L. a new race of perpetual flowering carnations has been developed.
The varieties of the new race may be distinguished from the Sim varieties by the following distinct characteristics: larger flowers, stronger perfume, wider colour range, larger, heavily serratted petals, thicker and stronger stems of normal length.
Unlike Sim types, the new varieties are fertile, producing many stamens.
The data of the comparative yield trials indicate that the new varieties are more vigorous and more productive both under field and greenhouse conditions.
In the greenhouse preliminary trials of certain varieties have produced yields in excess of 50 % over Sim types.
