Field inspections, field tracking, seedstock planted,
and record keeping are all integrated parts of a comprehensive Certification or Quality
Assurance program to insure genetic identity and purity of either seed or identity
preserved grain crops. Production sites need to be clearly mapped and be defined field
areas for specific crop or value-added grain production.
For seed and identity
preserved crops, one or more field inspections are commonly made at a convenient plant
growth stage(s) when phenotypic or morphological features can be assessed to determine
genetic purity and identity. Trained OSIA field inspectors apply sequential sampling to
measure genetic purity. Other agronomic field conditions such as weed infestation,
disease, insect pressure, ands volunteer plant of previous year crops are recorded on an
official field report.
OSIA field inspection services are offered in three areas. The first involves
application of Certified seed inspections which involve minimum standards to either pass
or fail seed fields or sites based on genetic purity standards and requirements. Minimum
state and federal standards must be met under this system for Certifying a variety. Public
and proprietary varieties, hybrids, or blends are commonly Certified, particularly for
international seed exports. A second system involves the application of minimum "custom"
seed quality minimum standards for non-Certified proprietary varieties, brands, hybrids or
blends under the green tag "Quality
Assurance" (QA) inspection system. Clients
are enabled to set their own standards and have OSIA field inspectors apply such standards
on a pass or fail basis. An optional QA green tag is available to clearly label seedlots
passing minimum standards of this non-Certified seed quality program. A third field
inspection service involves "Information
Only" inspections or client configured
custom inspections for either seed or identity preserved grain where the OSIA field
inspector takes a minimum number of sequential counts for genetic and purity and only
reports the findings without issuing a pass or fail status on the field. Supplemental
agronomic information such as yield estimates, crop progress reporting, herbicide efficacy
or resistance, disease, insect and weed pressure data are commonly recorded. This flexible
field inspection category allows OSIA to offer a wide range of ancillary services to
member grower, seed firms, the grain trade and end users.
