The breeder of a variety registered under this Act may apply in the prescribed manner to the Registrar to delete any part or to add to or alter the denomination of such variety in any manner not substantially affecting the identity thereof, and the Registrar may refuse leave or may grant it on such terms and subject to such limitations as he may think fit to avoid any conflict with the rights of the other breeders of the varieties registered under this Act.

(2)

The Registrar may cause an application under this section to be advertised in the prescribed manner in any case where it appears to him that it is expedient so to do, and where he does so, if within the prescribed time from the date of the advertisement any person gives notice to the Registrar in the prescribed manner of opposition to the application, the Registrar shall, after hearing the parties if so required, decide the matter.

(3)

Where leave is granted under this section, the denomination of the variety as altered shall be advertised in the prescribed manner, unless the application has already been advertised under sub-section (2).
