South Australian Seed Certification Scheme ° All forage, oilseed or field crop cultivars registered through a recognised registration process (including the Australian Plant Breeders Rights Office). Cultivars not bred in Australia must be registered in a comparable manner and have a morphological description in English available. ° All herbage, oilseed or field crop cultivars published in the official OECD cultivar list. For OECD certification of overseas bred cultivars permission of the certifying authority in the country of origin is also required. ° All new herbage, oilseed or field crop cultivars (or breeding lines) that can satisfy the acceptance requirements as specified in the “Conditions for the acceptance of Plant and Crop cultivars into the South Australian Seed Certification Scheme” (see Appendix 10.1). 3.4.2 Sowing Seed Refer to the individual Crop Standards to check the correct sowing seed for the crop to be grown. In general the following applies: Pedigree crops: Breeder’s or Pre-Basic seed must be sown to produce Basic seed. For crops producing certified class seed - Basic seed must be used where available - otherwise Seed Services (dependent on the species involved) may approve a suitable line of First Generation (C1) certified seed or Authorised Certified (AC) seed. Non-pedigree crops: The use of certified seed is not mandatory, but growers are strongly recommended to use certified seed nominated by Seed Services as the best available for genetic purity. 3.4.3 Cleandown all machinery Sowing machinery, and related seed transfer equipment, must be cleaned to ensure there is no risk of contamination to the sowing seed or the seed crop. A Seed Certification Officer may inspect machinery prior to sowing: • for crops sown to produce Pre-Basic or Basic seed • for growers new to the certification scheme • as an audit check on any grower participating in the certification scheme 3.4.4 Sowing Pre-Basic and Basic Seed Notify Seed Services at least five (5) days before the sowing of any crop intended to produce Pre-Basic or Basic seed. In some cases crop sowing may be supervised by a Seed Certification Officer. 3.4.5 Over-sowing perennial crops Over-sowing of perennial crops – with the exception of cv Hunter River lucerne - is not permitted with seed of the same or a similar species except: (i) where a seedling crop has failed to establish, follow-up sowing is permitted up to and including the season after the establishment year. (ii) where the area of sowing is both limited and defined and there are no existing mature plants of the same species in the area. Contact Seed Services for approval to re-sow or over-sow an existing perennial crop; including cv Hunter River lucerne seed crops. Note: No approval is required when over-sowing lucerne seed crops with cereals. Procedures and Standards for Seed Certification May 2002
South Australian Seed Certification Scheme 3.4.6 Forward labels from sowing seed to Seed Services Forward sowing seed labels to Seed Services within 21 days of sowing. The labels should be bundled together and identified by cultivar name, line number and date of sowing. Where the number of sowing labels per crop exceeds twenty, the applicant need only send the highest and lowest numbered labels – provided all label numbers of the seed sown are advised in writing to Seed Services. 3.5 Seed crop inspections 3.5.1 Seedling inspection Submitting the Certified Seed Crop Application form ensures that all necessary crop inspections are conducted, including a seedling inspection if required. In general: ° cereals, canola and pulses will not require a seedling inspection ° new forage/pasture/vetch crops will require a seedling inspection ° resown or regenerating annual legume crops may require a seedling inspection, depending on crop history. Refer to the individual Crop Standards for more information about the requirement for a seedling inspection. 3.5.2 Pre-harvest inspection All seed crops require a pre-harvest inspection. The pre-harvest inspection for most crop types is conducted during the flowering period. For some wheat cultivars, where chaff colour is an important identification characteristic, inspections may be delayed until this period. If varietal purity cannot be accurately assessed because the crop is: • severely lodged, diseased or herbicide affected, • obscured by a cover crop or weeds, or • stunted or poorly grown, the crop may be rejected from certification. Applicants receive a copy of all inspection reports conducted on their property. For proprietary cultivars, where requested, inspection reports will also be provided to the cultivar owner or licensee. The field inspector assesses the following during the pre-harvest inspection: • genetic purity - numbers of off-types - numbers of other cultivars - presence of seedheads from volunteer seedlings - number of other crop species • isolation • presence of weeds (including on check banks, channels and fence lines) • presence of disease • plant density • potential crop yield Refer to the individual Crop Standards for more information about standards for each species.
