North Dakota Administrative Code › Title 74 - Seed Commission › Article 74-04 - Seed Potato Certification Standards › Chapter 74-04-01 - Seed Potato Certification Standards › Section 74-04-01-01 - Definitions

Current through Supplement No. 393, July, 2024
As used in this chapter:
1. "Basic seed" means seed potatoes produced by means of
				  meristem, stem cutting, or other techniques for increase by certified growers.
2. "Certification" is strictly limited to the act of
				  endorsing that the potatoes have met the standards or requirements specified in
				  this chapter for seed potatoes. Certification does not mean or constitute any
				  warranty or representation that the potatoes are of the variety or selection
				  identified on the label, merchantable, disease free, fit for a particular
				  purpose or anything other than that the potato crop was inspected and that at
				  the time of inspection did meet the standards set forth in this chapter.
3. "Damaged by soil" means that the individual potato has
				  more than fifty percent of its surface affected by light caked soil, or more
				  than fifteen percent of its surface badly caked with soil.
4. "Dry land type", as allowed for long varieties only, means
				  not seriously misshapen.
5. "Except for shape", as allowed for long varieties only,
				  means the potatoes may be seriously misshapen.
6. "Experimental cultivar" means a numbered cultivar or
				  cultivar that has not yet been released from a breeding program or has been
				  produced under experimental conditions.
7. "Field year" means the time which is required for the
				  potato plant to complete the growing cycle from planting in the field until
				  maturity.
8. "Foundation seed" means a primary source of a genetically
				  identified variety from which increases are made.
9. "Grade" refers to the tuber quality, condition, and size
				  factors as specified in this chapter.
10. "Inspection" means visual examination or observation of
				  sample plants or tubers.
11. "Label" means an official tag or bulk certificate used to
				  identify certified seed.
12. "Latent diseases" means diseases not detectable by visual
				  inspection.
13. "Lightly caked with soil" means approximately one-eighth
				  of an inch [3.18 millimeters] in depth.
14. "Micropropagation" means the aseptic production of potato
				  plantlets, tubers, or sprouts utilizing meristem culture.
15. "Off type" means potato plants in a field that deviate in
				  one or more characteristics from that which is usual in the variety being
				  grown, or different from the cultivar, variety, strain, or selection stated on
				  the grower application for certification.
16. "Plant Variety Protection Act" means a federal Act passed
				  in 1970 which gives the owner of a novel variety the exclusive right to produce
				  and market that variety.
17. "Prenuclear seed" means plantlet propagation source
				  resulting from the use of aseptic propagation techniques either in the
				  laboratory or controlled environment.
18. "Seed potatoes" means Irish potato tubers to be used for
				  planting.
19. "Seed warehouse" means a building for seed potato storage
				  that is separate in structure and foundation from a commercial potato storage
				  unit.
20. "Selection" means a subgroup of a variety of potato.
				  Commonly used terms include line selection, clonal selection, or strain
				  selection.
21. "Seriously damaged by soil" means a potato having caked
				  soil on more than one-half of the surface or an equivalent amount of soil in
				  excessively thick chunks on a lesser area.
22. "Tolerance" means a permissible allowance for such
				  factors as disease, grade defects, and varietal mixture.
23. "Variety" means a plant group within a single botanical
				  taxon of the lowest-known rank which, without regard to whether the conditions
				  for plant variety protection are met, can be defined by the expression of the
				  characteristics resulting from a given genotype or combination of genotypes,
				  distinguished from any other plant grouping by the expression of at least one
				  characteristic, and considered as a unit with regard to the suitability of the
				  plant grouping for being propagated unchanged. A variety may be represented by
				  transplants, plants, tubers, tissue culture, plantlets, and other matter.
24. "Virus tested" means tested for latent viruses by methods
				  established by the state seed department.
25. "Zero tolerance" means that no amount is permissible. It
				  does not mean that the seed is absolutely free of a disease or disease-causing
				  agent, grade defect, or varietal mixture, but that none was found during
				  inspection.
