TRITICALE (X.Triticosecale (Witmack)

 

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 triticale seed.

 

II. Land requirements

 

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

 

III. Field Inspection

 

A minimum of two inspections shall be made between the ear emergence and harvesting of the seed crop.

 

IV. Field Standards

 

A. General requirements

 

1. Isolation

Barley seed fields 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                                                                                    3                    3

Fields of the same variety not conforming to the

varietal purity requirements for certification                                                        3                   3

Fields of other barley with infection of loose smut

(Ustilago nuda (Jens.) Rostr.) disease in excess

of 0.10% and 0.50% in foundation and certified seed respectively                    150                150

***Plants infected  by ergot disease                                                            0.020                    0.040


* Standards for offtypes and inseparable other crops shall be met at final inspection before harvesting and for loose smut of barley at any inspection conducted between ear emergence and harvesting.

** Inseparable other crops shall be:

oats, wheat, barley,  gram and triticale.

*** In case of ergot disease, the seed fields can, however, be certified if diseased plants are removed and burnt and the fields show, on re-inspection, infection not more than the maximum permissible level.  Only one such re-inspection shall be permitted.
