CROP IMPROVEMENT ASSOCIATION:
The Tennessee Crop Improvement Association is an incorporated,
non-profit organization of seed growers. State legislation designates
the Association as the official seed-certifying agency in Tennessee.
Requirements for certification of seeds conform to the Federal Seed
Certification Regulations and the Association of Official Seed Certifying
Agencies. The Association works in cooperation with seed growers,
seedsmen, the State Department of Agriculture, University of Tennessee
Institute of Agriculture, Agricultural Extension Service, and Agricultural
Members are primarily persons or firms growing seed on their own
land, rented land or contracting for the production of seed and
who make certified seed production a definite part of their farming
operation. However, any person or firm interested in promoting the
objectives of the Association may become an associate member.
The Association maintains headquarters at 3205-C Hwy 46 South Dickson
TN 37055, and renders the following services:
To maintain and make available to the public sources of high quality
seeds and propagating materials of superior varieties so grown and
distributed as to insure genetic purity and identity.
Seed certification is accomplished by means of inspection of fields,
seed analysis and regulations for checking production, harvesting
and cleaning of each seed lot.
Varietal purity is the first consideration, but seed quality factors
such as germination, inert matter and mixtures of other crop and
weed seeds are important.
Tennessee seed certification is designed, therefore, to maintain
not only the genetic purity and identity of crop varieties but also
provides safe standards for germination and mechanical quality factors.
The function of certification is to provide a process by which
to propagate or increase a variety through a system of known generations
by which the genetic purity is maintained. New varieties are released
by either a public (University or USDA) or private entity.
The Association renders the following services:
1. Publishes and distributes the Tennessee Seed Certification Standards.
This publication complies with the minimum genetic standards required
by the Association of Official Seed Certifying Agencies and federal
2. Maintains a record of origin or pedigree records of each grower
3. Provides its members with sources of foundation class seed.
4. Provides field inspection, source for laboratory testing, printing
of certification and analysis tags, labeling stencils and bags for
5. Gathers semi-annually a Certified Seed Directory listing acreage
of seed by variety and class available from its members to be posted
on the TCIA website.
6. Directs an educational and advertising program concerning the
merits of certified seed.
7. Holds annual training schools for field inspectors of all seed
crops before inspection work begins.
8. Holds annual training schools for seed inspectors who draw the
official samples of certified seed for laboratory testing. They
also determine if seed lots are bagged and labeled according to
9. Conducts grow-out tests on a portion of the official sample
of foundation, registered, and certified seed lots of soybeans and
small grains. These tests are conducted at the Knoxville and Milan
Experiment Stations to evaluate how well the member maintains genetic
purity of his seed increase.
10. The basic function of the seed certification program is to
serve Tennessee Agriculture.
11. Tennessee Crop Improvement Association does not buy nor sell
12. Tennessee certified seed is distributed through the established
seed marketing channels.
13. Production of certified seed is increasing in Tennessee. This
reflects an increased acceptance and use of certified seed by both
seed dealers and farmers.
This progress also reflects a measure of the service by the seed
