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  hybrids of cabbage, cauliflower, broccoli, knol-kohl and chinese

cabbage heading and non heading).

 

   B.     The General Standards are amplified as follows to apply specificiation to the hybrids of cabbage,

cauliflower, broccoli, knol-kohl and chinese cabbage (heading and non-heading).

 

    1. Eligibility requirements for certification

 

 (a) A hybrid is one  to be planted for any use except seed production. It may be anyone of the following  

 

        (i) Single cross - the first generation  resulting from the controlled crossing of the two

approved self- imcompatible but cross-compatible inbred lines. It  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 together, mixed  and certified.

    

        (ii) Double cross -the first generation  resulting from the controlled crossing of the two

approved self- imcompatible but cross-compatible single crosses.

 

        (iii) Three way cross -the first generation resulting from controlled crossing of an approved inbred

   line and certified single cross being self-incompatible individually but cross compatible to each other 

 

    2.  Classes and sources of seed

 

a. Only the class "Certified" shall be recognised

b. A hybrid to be certified must be produced from certified Foundation seed or seed stocks approved

    by the Certification Agency.

 

II. Land requirements

 

    Land to be used for seed production of  the hybrids of  cabbage, cauliflower, 

broccoli, knol-kohl and chinese cabbage (Heading and non heading) shall be free from volunteer plants.

 

II. Land requirements

    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 before harvesting to check offtypes, seed borne 

        diseases and other relevant factors.

 

IV. Field Standards

 

A. General requirements

 

1. Isolation

 

    Seed fields of hybrids 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:
