Precontrol standards

If field inspection shows one or more of the following, the applicant may request that seed certification be based on the results of a precertification grow-out test approved by the North Dakota state seed department. 1. Inadequate isolation. 2. Too few male parent plants shedding pollen when female plants are receptive. 3. Excess off-types not to include wild types. In such cases at least two thousand plants must be observed and meet the following standards before hybrid and inbred seed can be certified from fields with problems listed above. Maximum Permitted Factor Hybrid Inbred Sterile plants 5.0% Sterile or fertile plants 5.0% Morphological off-types 0.5% 0.5% Wild types 0.2% 0.2% Total (including above types) 5.0% 5.0% For nonoil types, hybrid seed which contains not more than fifteen percent sterile plants may be certified. If it contains eighty-five percent to ninety-five percent hybrid plants, the percentage of hybrid shall be shown on the certification label.
