A. ABOUT THE OBJECTIVE DESCRIPTION FORM
This objective description form is designed as an aid for the identification of wheat varieties to provide sufficient information for pedigreed seed crop inspection and variety verification purposes. Companion documents include the "Variety Registration Application Form" and the "Procedures for the Registration of Crop Varieties in Canada," both of which are available on the CFIA Variety Registration Office homepage at http://www.inspection.gc.ca/english/plaveg/variet/vartoce.shtml. This objective description form lists characteristics to be used as the basis for developing the description of wheat varieties. It is recommended that the form be completed in as much detail as possible to ensure that an accurate description of the variety be on record. Uniformity and stability must be sufficient to ensure that the genetic purity of the variety has not been compromised during the development of the variety or during the seed multiplication process. However, accurate information on variability within the variety is essential for distinguishing between variants and off-types during the seed multiplication process. Information on this document may be accessible or protected as required under the provisions of the Access to Information Act. Information that could cause you or your organization injury if released is protected from disclosure as defined in Section 20 of the Access to Information Act. Please indicate clearly traits that are considered to be confidential. Note that sufficient information must be considered public to facilitate crop inspection and certification. B. CHARACTERISTICS The candidate variety must be described for all characteristics designated on the form with a pound symbol (#). A rating system of 1-9 provides a scale for describing most characteristics in this form. To rate characteristics, select a value that best corresponds to the state indicated. Characteristics may be rated with intermediate values where the characteristic grades gradually from one extreme to another. For example, where the descriptors for a characteristic are described as: small (3), medium (5), large (7); other values of 1, 2, 4, 6, 8 or 9 may be selected. Each characteristic on this form has been arranged in a tabular format allowing the candidate variety (CV) and up to four reference varieties (R1 to R4) to be described. In the case of hybrid crops, the hybrid and parents can be described using CV, R1, and R2 respectively. Please note that the mandatory traits do not apply to the inbred line descriptions for hybrid varieties. Information on reference varieties is useful but not mandatory for variety registration. Any reference varieties used must be registered for sale in Canada.

APPENDIX ILLUSTRATIONS AND NOTES 2.1 Coleoptile colour
(Method for the determination of anthocyanin colouration)
(1) Place 20 non-dormant seeds on moistened filter paper covered with a petri dish lid during germination and place in the laboratory or greenhouse. (2) After the coleoptiles have reached a length of about 1 cm in darkness, they are placed in artificial light (daylight equivalent), 12,000 to 15,000 lux continuously for 3-4 days at 15 to 20°C. (3) Make the assessment on the anthocyanin colour about one week after coleoptiles are fully developed. (4) The reference variety should be included.
2.2 Seedling growth habit The growth habit should be assessed visually from the attitude of the leaves and tillers. The angle formed by the outer leaves and the tillers with an imaginary middle axis should be used.

(Procedure for determining the reaction of wheat seeds to phenol)
(1) Obtain 20 seeds from a uniformly mixed sample. (2) Soak seeds in distilled water for 16 to 20 hours. (3) Rinse seed with tap water and remove excess water from the seed surface. (4) Place two 9 cm filter papers in a petri dish. (5) Place the seed on the filter paper within the petri dish. Remember to carefully orient the seed so that
the crease side faces down. (6) Using a pipette, evenly distribute a 1% solution of freshly prepared phenol solution over the seeds. The
seeds should be 3/4 covered by 1% phenol solution. (7) Cover the petri dishes and place them in a laboratory out of direct sunlight at a temperature oscillating
between 18 and 20°C.
Wheat Objective Description Appendix
Version Date: 2008/09 21
(8) Make observations four hours after adding the 1% phenol solution. It is recommended that a book of means and colourimetric nomenclature chart be used to evaluate the colour.
(9) The reaction of phenol solution on treated seed is difficult to interpret. Seed treated with Panogen and
certain other products may provide reliable results, however, seed treated with Vitaflo do not react to phenol. As a result, seeds treated with Vitaflo need to have the pesticide removed before subjecting them to this test. This can be done using the following procedure:
Pour 75 ml of methanol in a beaker containing 400 seeds. Stir the seed in solution for 5 minutes using a glass stirring rod. Decant the methanol and rinse the seed in running water for 2 minutes.
12.0 Reaction to Pesticides In order for claims of pesticide tolerance to be made, data must be submitted to support these claims. Although there is no minimum amount of data required for the purposes of variety registration, for the purposes of the pesticide registration or for the variety to be listed on a pesticide label, the requirements of the Pest Control Products Act must be met. Under the Pest Control Products Act, if an applicant submits data to demonstrate tolerance to a specific herbicide, this data cannot be extrapolated to all chemicals within that class of compounds. Similarly, data can only be submitted as it relates to the intended use, i.e. data submitted on tolerance of the plants under sprayed conditions cannot be extrapolated to tolerance to residual herbicides.
