Details of Application Application Number 2007/328 Variety Name ‘Ivoryduchess’ Genus Species Prunus persica Common Name Peach Synonym Whiteduchess Accepted Date 29 Feb 2008 Applicant Lowell G. Bradford, Le Grand, CA, USA Agent Buchanan's Nursery, Hodgsonvale, QLD Qualified Person Peter Buchanan Details of Comparative Trial Overseas Testing US Patent and Trademark Office Authority Overseas Data US PP 17,282 Reference Number Location Overseas data was verified at Buchanan’s Nursery, 262 Breydon Rd, Hodgsonvale, QLD 4352. Descriptor Peach/Nectarine (Prunus persica) TG/53/6. Period 3 years. Conditions Normal growing conditions for Hodgsonvale QLD. Some drought conditions were experienced. Supplemental irrigation was required for the duration of the trial. Trial Design 10 trees of the proposed variety and the comparator were planted at 1.5m x 5m tree spacing. Irrigation was applied and industry standard management practice was used. Measurements Observations of tree and fruit characteristics were made to confirm the variety is true to type and to see if there were any climatic or geographic variations. RHS Chart - edition N/A Origin and Breeding Controlled pollination: The variety was developed as a first generation cross using an unnamed white nectarine as the selected seed parent and an unnamed yellow fleshed peach as the selected pollen parent. The unnamed seed parent was a first generation cross of ‘Spring Bright’ nectarine by an unnamed white fleshed nectarine. The unnamed pollen parent was a first generation cross of ‘Spring Bright’ nectarine by an unnamed yellow peach. A single tree was selected from the stated cross and claimed as the new variety. Subsequent to the origination of the new variety it was asexually reproduced by budding and grafting and such reproduction of plant and fruit characteristics were true to the original in all respects. Breeder: Lowell G. Bradford, Le Grand, CA, USA.

Fruit ground colour of flesh whitish Fruit shape round Fruit acidity very low to low Stone adherence to flesh present Most Similar Varieties of Common Knowledge identified (VCK) Name Comments ‘Ivory Princess’ ‘Ivory Duchess’ peach is most similar to ‘Ivory Princess’ peach by producing fruit that is clingstone in type, white in flesh colour, mostly red in skin colour, firm in texture, and sub-acid in flavour. It is distinguished from ‘Ivory Princess’ by requiring less chilling hours and producing fruit that is about eight days earlier in maturity.
