Current through Register 2024 Notice Reg. No. 12, March 22, 2024
(a) Generally. Inspection and testing
procedures prescribed in this article may be made by the University of
California and the Department, and shall be conducted in an approved manner at
times determined as suitable by the Department. In the testing procedures
required in this section, the Department may approve the substitution of other
indicator plants if equally suitable or may approve indexing on a fewer number
of indicator plants, if the plant being tested is itself a good indicator for
the sunblotch viroid or may approve other procedures for testing if determined
equally suitable. Additional inspections or tests other than provided in this
section may be required by the Department if any of these conditions exist:
seasonal conditions or other factors tend to obscure the sunblotch viroid
symptoms or make adequate inspection impossible; sunblotch viroid infection is
suspected; sunblotch viroid symptoms may be masked in a particular
variety.
(b) Eligibility of Stock.
(1) Candidate Tree. Each candidate tree shall
be assigned an in-test identification number and shall be either:
(A) indexed for sunblotch viroid in an
approved greenhouse facility under the supervision of the University of
California and the Department. Each index test shall include indexing for
sunblotch viroid by inoculating a minimum of 12 Guatemalan or West Indian
variety avocado seedlings grown from registered foundation stock and
graft-inoculated with tissue from the candidate tree. The inoculated seedlings
shall be observed for a period of at least two years, except where results show
a candidate tree is infected with sunblotch viroid. If no evidence of sunblotch
viroid is found, the candidate tree may be registered as a foundation stock
tree.
or,
(B) tested using the approved Polymerase
Chain Reaction (PCR) developed to identify the sunblotch viroid. This test
shall be performed by the University of California. Testing shall done in
accordance with procedures developed by R. J. Schnell in 1997 as amended by J.
A. Dodds in 1997. These procedures are available from the department upon
request.
If no evidence of sunblotch viroid is found, the
candidate tree may be registered as a foundation stock
tree.
(2)
Foundation Stock Tree. Candidate trees found to be free of sunblotch viroid
following testing may be registered for use as primary sources of stock for the
production of registered seed and scion materials. Registration is for a
two-year period beginning with the start of the testing of the candidate tree.
The in-test identification number of each candidate tree will become the tree
registration number unless registration is refused or canceled as hereinafter
provided.
(3) Increase Block. Trees
propagated using foundation stock seed and budwood shall be acceptable for
planting in an increase block. Propagative material from an increase block may
be planted in the same increase block to replace plants or increase its size or
to establish other increase blocks.
(A) The
Department will assign a registration block number to each applicant's increase
block upon receipt of an acceptable application and the proper fees.
(B) Registration of increase block trees
shall be for a period of two years from June 30 in the calendar year in which
the registration was issued.
(C)
Registration of an increase block may be continuous provided application is
filed with the Department prior to the expiration date of the original
registration.
(4)
Registered Nursery Tree. Nursery trees shall be propagated using registered
seed and scionwood.
(A) Seed and budwood
collection shall be done in a manner approved by the Department.
(B) The Department, upon receipt and
acceptance of an application and fees for a registered nursery planting, will
assign a registration number to the nursery planting block.
(C) Registration of a nursery planting shall
be for a period of two years from June 30 in the calendar year in which the
registration was issued.
(c) Refusal, Suspension or Cancellation of
Registration. Registration may be refused, suspended, or canceled for any
planting or portion thereof when:
(1) The
requirements of this article have not been met, or
(2) The plant or plantings are found to be
sunblotch viroid infected or off-type, or
(3) A registered tree is found sunblotch
viroid infected and it is determined that plants propagated from it also are
liable to be infected, or
(4) For
any reason the identity of a plant or planting becomes uncertain or has not
been properly maintained, or
(5) A
registration number is misused or misrepresented.
