When under exceptional circumstances, six counts of 10,000 plants each cannot be conducted due to the variety, and the nature or number of the variants and/or off-types that are found (based on experience with the variety or on three initial plant counts of 1,000 plants), or where the variety description indicates a single variant with maximum allowable levels in excess of 200 per 10,000 plants.

1. The following procedure will be used for species for which the CSGA standards for off-types or other varieties of the same crop kind are:

Foundation and Registered: 1 per 10,000 plants
Certified: 5 per 10,000 plants

A = take 15 additional plant counts of 1000 plants to allow CSGA to clearly determine if the crop meets current standard;
B = take 10 additional plant counts of 1000 to allow CSGA to clearly determine if the crop meets current standard;
C = take 5 additional plant counts of 1000 plants to allow CSGA to clearly determine if the crop meets standard at demoted level;
D = discontinue counts.

2. The following procedure will be used for species for which the CSGA standards for off-types or other varieties of the same crop kind are:

Foundation and Registered: 2 per 10,000 plants
Registered: 4 per 10,000 plants
Certified: 20 per 10,000 plants

A = take 15 additional plant counts of 1000 plants to allow CSGA to clearly determine if the crop meets current standard;
B = take 10 additional plant counts of 1000 to allow CSGA to clearly determine if the crop meets current standard;
C = take 5 additional plant counts of 1000 plants to allow CSGA to clearly determine if the crop meets standard at demoted level;
D = discontinue counts.

In those exceptional circumstances where reduced counts are used, this must clearly be highlighted along with an explanation of why the reduced count procedure was used. When reduced count sizes are used, the inspector must immediately provide the grower, the CSGA, and the lead inspector or inspection supervisor with a copy of the Report of Seed Crop Inspection.
