PETUNIA

(Petunia spp.)

I. Application and Amplification of General Seed Certification Standards

    The General Seed Certification Standards are basic and, together with the following specific standards constitute the standards for certification of  hybrid seeds

I. Land requirements

    Land to be used for seed production of Petunia shall be free of volunteer plants..

III. Field Inspection

A minimum of twp inspections shall be made as the first  inspection shall be made the first flowering/during flowering to check  isolation, offtypes etc. and second at fruiting stage/maturity prior to harvesting.

IV. Field Standards

A. General requirements

1. Isolation

        Seed fields of Petunia shall be isolated from the contaminants shown in the column 1 of the Table below by the distances specified in columns 2 and 3 of the said Table:

        Contaminants                                                                                   Minimum distance (meters)

                                                                                                                Foundation        Certified

            1                                                                                                         2                     3

Fields of other varieties                                                                                 600                 300

Fields of the same variety not conforming to 

varietal purity requirements for certification                                                    600                 300  

B. Specific requirements

            1                                                                                                        2                           3

      Offtypes                                                                                               0.050                    0.10  

      * Plants affected by designated diseases                                                0.10                     0.20  

    *  Standards for offtypes shall be met at and after flowering and for designated diseases at final inspection.

** Designated diseases shall be:

 Leaf bright                                (Alternaria alternate(Fr.) Kiessler)

Crown rot                                  (Phytophthora parasitica Dast)
