[Regulations by the Minster]

1.   Title

These Regulations may be cited as the Plant Variety (Potato Seed) Regulations.

2.   Interpretation

   (1)   In these Regulations unless the context otherwise requires—

“control growing” means a test where growing potato plants are examined to determine cultivar purity and/or virus infection;

“cultivar” means a subdivision of any species which can be distinguished from other subdivisions of that species by means of growth, plant, fruit or other characteristics;

“defect index” means a figure giving the status of a growing crop, a control growing plot or a potato seed lot taking into consideration both frequency and severity of the defects;

“isolation” means a required distance between two crops of the same species in order to prevent contamination either mechanically or by pollination;

“off-type” means a plant which does not show the recognised and acceptable habits and characteristics of the cultivar being grown; and

“seed class” means a step in seed multiplication system well defined in respect of another seed, standard of cultivation and seed quality.

   (2)   Unless the context otherwise requires words and expressions not defined in these Regulations but defined in the Plant Variety and Seeds Regulations, shall, in these Regulations, have the meaning assigned thereto.

3.   Act to apply to potato seed

   (1)   Potato seed is hereby prescribed to be seed to which the Act applies.

   (2)   No potato shall be sold as seed unless it has been certified by the Controller of Seeds in accordance with these Regulations.

   (3)   No potato seed shall be certified under these Regulations unless it has been produced and inspected, and attains the standards, as herein provided.

4.   Certification of potato seed

   (1)   Only cultivars which have been approved by the Controller of Seeds shall be eligible for certification.

   (2)    Potato seed shall be certified in six classes in accordance with the First Schedule.

   (3)    The standards for certification shall be in accordance with the Second Schedule.

5.   Registration as grower

   (1)    An application for registration as a grower of potato seed shall be made in accordance with Part VIII of the Act.

   (2)    An application shall not be approved if it is in respect of land on which, during the preceding three years, potatoes or other Solanaceous crops have been grown.

6.   Evidence of class of seed grown

The grower shall plant the class of seed appropriate for his production; and shall retain such evidence of that class as may be sufficient to satisfy the Certifying Authority in that behalf.

7.   Field inspection

   (1)   An inspector carrying out a field inspection shall reject a crop for certification if he is satisfied that—

      (a)   the crop is so heavily contaminated with weeds as to render it unfit as seed;

      (b)   the crop is so heavily infested with blights as to render it unfit as seed;

      (c)   the isolation distance prescribed in the Second Schedule is not met;

      (d)   the standard relating to aphids as prescribed in the Second Schedule is not met;

      (e)   the standard relating to the removal from the field of undesirable plants as prescribed in the Second Schedule is not met; or

      (f)   the defect index as prescribed in the Second Schedule is in excess of 30.

   (2)   In respect of every field inspection carried out under these Regulations, a report in the appropriate form prescribed in the Third Schedule shall be rendered by the inspector and counter-signed by the grower.

8.   Virus post control

   (1)    In respect of a crop intended for the production of pre-basic seed (S) or basic seed (SE), the grower shall give notice to the Certifying Authority informing him when the haulms have been destroyed and when he intends to lift the potatoes in order that before the potatoes are lifted samples may be taken for purposes of a virus post control.

   (2) In respect of every virus post control carried out under these Regulations, a report in the appropriate form prescribed in the Third Schedule shall be rendered by the Certifying Authority.

9.   Grading and packing

   (1)   Potato seeds shall be graded in three sizes in accordance with the following specification:

      (a)   Small 30-40 millimetres;

      (b)   Medium 41-50 millimetres;

      (c)   Large 51-60 millimetres.

   (2) Potato seeds shall be packed in pockets or other containers approved by the Certifying Authority.

10.   Tuber control

   (1)   Potato seed shall be presented for tuber control—

      (a)   not earlier than fourteen days and not later than nine months after it has been lifted; and

      (b)   in seed lots not exceeding five tonnes each.

   (2)   In respect of every tuber control carried out under these Regulations, a report in the appropriate form prescribed in the Third Schedule shall be rendered by the inspector and counter-signed by the grower.

11.   Control growing

   (1)   Potato seed samples shall be presented for control growing in accordance with instructions issued from time to time by the Certifying Authority.

   (2)    Potato seed shall be stored, both before and after certification, in a manner satisfactory to the Certifying Authority—

      (a)   so as to avoid disease, infection and contamination thereof;

      (b)   in buildings disinfected with a disinfectant approved by the Certifying Authority; and

      (c)   in lots separate from ware potatoes and other potato seed lots.

   (3)   When potato seed is stored in an open shed, in addition to the provisions of sub-regulation (2), volunteer Solanaceous or old sprouting potato tubers shall not be allowed within fifty metres of such open shed.

   (4)   When an inspector is satisfied that potato seed has been stored contrary to the provisions of this regulation, he may—

      (a)   in the case of potato seed which has not been certified, refuse certification; or

      (b)   in the case of potato seed which has been certified, cancel such certification.

13.   Validity of certification

Unless cancelled earlier, the validity of a certification for potato seed shall be sixty days from the date of the tuber control:

Provided that upon the expiry of a certificate a further tuber control may be carried out and the seed may be recertified for a like period.

14.   Appeals

Any person aggrieved by any decision under these Regulations of an Inspector may appeal to the Certifying Authority and to the Minister from any decision of the Certifying Authority.

NOTES:

Field inspection

1.   The isolation refers to the distance between the potato crop for certification and potato crops of lower quality classes or volunteer potato plants. Between different cultivars of the same quality class the isolation shall be at least 5 metres.

2.   A potato crop will be considered heavily infested with aphids if there are more than 150 per 100 leaves taken from the lower half of a plant. Provided that haulm destruction of a heavily infested crop is carried out within seven days from the date of discovering by inspection, it may be cleared by field inspection.

3.   Undesirable plants shall be cleared away as soon as possible by removing both the haulms and the tubers to a distance of at least 30 metres from every edge of the field.

4.   Diseased plants, plants of other cultivars and off type plants shall be recorded as percentages by number; and the percentages found shall be multiplied by the appropriate factors set out in note 5, and the various products so obtained shall be added together to give the defect index for the particular field.

5.   The factors to obtain the defect index for a field inspection shall be as follows:

Defeci

6. Samples for virus post control shall be taken in the field after haulm destruction. A minimum of one thousand tubers per field shall be sampled.

7.   The determination of virus shall be done by serological methods and/or by occular inspection. The result shall be given as a percentage by number of infected tubers.

Tuber control

8.   From each lot presented for tuber control at least five primary samples of a minimum of forty tubers each shall be drawn. The primary samples mixed together shall form the working sample to be examined. At least 500 tubers per seed lot shall be examined.

9.   The working samples shall be washed, and all the tubers shall be cut through before they are examined.

10.   Diseased, damaged and severely mis-shaped tubers and tubers deviating in size from the grade size shall be recorded as percentage by number; and the percentages found shall be multiplied by the appropriate factors as set out in note 11 and the various products so obtained shall be added together to give the defect index for the seed lot.

11.   The factors to obtain the defect index for the tuber control of a potato seed lot are as follows:

12.   For the purposes of an examination the following shall be ignored:

      (i)   attacks by Black scurf, Common scab and Powdery scab if the area covered is less than 10 per cent of the total tuber area;

      (ii)   mechanical damages, cut worms damages, other insect damages and cracks if the area covered is less than 10 per cent of the total tuber area or if the penetrating depth is less than 10 per cent of the tuber length;

      (iii)   internal heat necrosis and spraing covering less than 10 per cent of the cut surface;

      (iv)   diffuse brown spotting; and

      (v)   size deviation of less than 5 per cent of the total tubers examined.

13.   If in the case of defects with a factor of 10 or 3, the product of the percentage of defective tubers and the appropriate factor exceeds 5, the seed lot shall be rejected.

Control growing

14.   (i)   From every certified potato seed lot of the classes S1 to E2 a sample of at least 500 tubers shall be drawn for the purposes of control growing.

      (ii)   The potato plants in the control plots shall be inspected frequently during their growing period and cultivar contaminations, diseases and other defects shall be recorded as percentages by number. The percentages found shall be multiplied by the various factors set out in Note 5 to obtain the defect index for a control growing.

General

1.   For Wart Disease (Synchytrium endobioticum); Bacterial Wilt; Brown Rot; Ring Rot (Pseudomonas solacearum and Corynebacterium sepedonicum) and Potato Cyst Nematode (Globodera sp.) the tolerance is nil at field inspection, tuber control and control growing for all classes.

2.   If a potato seed lot does not reach the standards for the class it has been grown; it may be approved in a lower class, or rejected for certification if found to be of a lower standard than that prescribed for Certified Seed 4th generation.
