Certification by the Department shall not imply or be construed
as any warranty of the Department, the school, or its employees as to the
condition of caneberry nursery stock. The following requirements and conditions
shall be met in order to qualify for consideration of certification of
caneberry nursery stock:
(1) The
applicant for such certification under these regulations shall be responsible
for the selection of the location and the proper maintenance of a planting
being grown. The applicant shall also be responsible for maintaining the
identity of all said nursery stock. Land selected for the production of
Foundation, Registered, or Certified Stock shall not have grown any solanaceous
crop or any crop plant within the genus
Rubus within the
previous five years unless said plants were propagate in accordance with the
provisions of these regulations. The selected site must be free of any evidence
of the presence of Agrobacterium
rubi or
A.
tumefaciens as indicated by the absence of:
(a) Overgrowths or tumors on crowns, roots,
stems, or leaves; and of
(b)
Excessive or abnormal development of organs with or without
tumefactions;
(c) The presence of
subsections (a) or (b) of this section on any known host plants in the site or
within 30 feet will be cause for rejection. The Department or school shall be
notified by the applicant in advance of the planting, replanting, or digging of
caneberry nursery stock in order that necessary inspections may be made or
approval granted prior to the performance thereof.
(2) Each planting shall be located in an area
in which viruses or other systemic pathogens affecting caneberries are not
prevalent and in which there is adequate isolation from plantings of
caneberries producing fruit. Cultivars within a planting must be adequately
separated in an approved manner. Prior to acceptance of the planting site one
of the following procedures shall be followed by the nurseryman:
(a) Present acceptable records to the
Department of nematode sampling of the land in question which show that plant
parasitic nematodes are not present in harmful quantities; or
(b) Fumigate the land in accordance with
approved commercial practices compatible with current recommendations of the
Oregon State University Extension Service.
(3) For inspection purposes, one percent of
the plants or 12 plants, whichever is less, from a Foundation Block must be
allowed to produce mature fruit. Such plants are not to be harvested for
certification and shall be removed from the planting after inspection for
trueness-to-name.
(4) Foundation
Blocks shall be enclosed by an approved screenhouse. A minimum of three percent
of the individual plants planted therein that will be used for further
propagation shall be tested biennially by indexing. Progeny plants will be
identified by clone numbers.
(5)
Each planting shall be kept in a thrifty growing condition and pests shall be
kept under intensive control. Diseased or off-type plants will be rogued.
Because of the problem of development of seedlings in the planting and the
opportunity for flower infection by certain viruses, flowers will not be
allowed in certified plantings except for section (3) of this rule.
(6) For purposes of determining eligibility
of caneberry nursery stock for certification in accordance with OAR
603-051-0590 of these regulations, the following shall apply:
(a) To be acceptable for a planting in a
Foundation Block a plant shall be:
(A)
Nuclear Stock; or
(B) Foundation
Stock which is a progeny of a plant from a Foundation Block that was tested the
previous season in a program of indexing acceptable to the Department;
or
(C) Progeny of screenhouse grown
Foundation Block plants removed from Nuclear plants by no more than four years.
The adequacy of the applicant's screenhouse shall be reviewed annually by the
certifying agencies.
(b)
To be acceptable for planting in an Increase Block, a plant shall be Nuclear or
Foundation Stock;
(c) To be
acceptable for planting in a Certified Block, a plant shall be Nuclear Stock,
Foundation Stock, Registered Stock, or first-year Certified Stock. (See
Diagram 1.);
(d)
Caneberry plants in outdoor Increase Blocks shall be planted in rows not less
than eight feet apart;
(e) No plant
separated from Foundation Stock by more than three years of vegetative
propagation shall be eligible for certification.
