I. Application and Amplification of General Seed Certification Standards
A. The General Seed Certification Standards are basic and together with the following specific standards
constitute the standards for certification of the seeds of foundation single crosses of cabbage, cauliflower,
broccoli, knol-kohl and chinese cabbage (heading and non heading).
B. The General Standards are amplified as follows to apply specifically to the foundation single crosses of cabbage,
cauliflower, broccoli, knol-kohl and chinese cabbage (heading and non-heading).
1. Eligibility requirements for certification
A foundation single cross to be eligible for certification must be produced from two approved inbred lines both of
which shall be self- incompatible but cross-compatible, the sources of which shall assure their identity and are approved
by the Certification Agency.
2. Classes and Sources of seed
(a) A foundation single crosses shall consist of the first generation hybrid resulting from the controlled crossing of the two
approved self- imcompatible but cross-compatible inbred lines. The foundation single crosses may be of three types depending
upon the procedure of seed producation;
- seeds of only female parent are harvested and certified;
- seeds of both parents are harvested separately and certified;
and
- seeds of both the parents are harvested, mixed together and certified.
(b) The foundation single cross shall be used for production of hybrid seed.
II. Land requirements
Land to be used for seed production of foundation single crosses of cabbage, cauliflower,
broccoli, knol-kohl and chinese cabbage and non heading) shall be free from volunteer plants.
III. Field Inspection
A minimum of three inspections shall be made as follows:
1. the first inspection shall be made before flower stalk development to check isolation, offtypes
including type of heads (curds or knobs), outcrosses , planting ratio, and other relevant factors;
2. the second inspection shall be made during flowering to check isolation, offtypes and other relevant
factors;
3. the third inspection shall be made at maturity and prior to harvesting to check offtypes, seed borne
diseases and other relevant factors.
IV. Field Standards
A. General requirements
1. Isolation
Seed fields of foundation single cross of the seed crops mentioned in column 1 of the Table below shall be isolated from
the contaminants shown in column 2 of the Table below by the distances specified in column 3 of the said Table:
