Plant Varieties Journal Vol. 23 Number 4 Details of Application Application Number 2010/143 Variety Name ‘Chopper’ Genus Species xTriticosecale Common Name Triticale Synonym Nil Accepted Date 04 Aug 2010 Applicant Australian Grain Technologies Pty Ltd, Adelaide, SA Agent N/A Qualified Person Gil Hollamby Details of Comparative Trial Location Roseworthy, South Australia Descriptor Triticale TG/121/3 Period 2010 Conditions A comparative trial was sown on the Roseworthy Campus of the University of Adelaide. In 2009 the area carried a faba bean crop which was harvested for grain and the resultant stubble was baled and removed. Pre-seeding herbicides Boxer Gold (2.5L), Roundup Powermax (1.5L) and Lontrel (100ml) together with an insecticide Imidan (150ml) were applied prior to seeding on 3 Jun 2010. 90kg DAP fertiliser was applied with the seed. The season was very favourable for growth of the crop and of weeds and disease, so the trial was sprayed post emergence with Hussar OD (100ml), Lontrel (100ml) to control weeds, with Rogor insecticide (100ml), fungicide Opus 125 (500ml) for stripe rust and powdery mildew. Crop performance was enhanced with the application of micrunutrients and urea (50kg). Late in the season aphids needed to be controlled and Chlorpirifos (400ml) and Alphacypemetherin (200ml) was applied. At no time was the trial stressed by the weather so varieties were able to fully express their genetic potential. Trial Design Randomised block design of 3 blocks and 16 entries consisting of comparators and potential candidates. Sown in 12 ranges of 4 plots wide, block 1 being in ranges 1 to 4 and so on. Plots were 1.25m wide (5 rows) and 3.2m long. There were approximately 1000 plants per plot. Measurements Qualitative characters were recorded for every replicate at the appropriate growth stage. Quantitative characters were measured on 10 randomly sampled plants from each replicate, the samples being taken at the appropriate growth stage or after maturity. Statistical analyses were completed using GENSTAT software. RHS Chart - edition N/A Origin and Breeding Controlled pollination: A single cross between a University of Adelaide breeders line (TX93-19-2D-3) and the variety ‘Treat’ was made in 1999. A total of 25 F 2 derived doubled haploids were produced from this cross in 2000. Seed was multiplied in the Page 241 of 322
