Seed increase, 2007 lines
The 2007 set cleared quarantine at SARDI and was supplied to the Germplasm Evaluation Project and sown in the last week of July 2007 for increase. Subsamples of 5-10 seeds were supplied to Harbans Bariana at Sydney University, Cobbitty, for rust evaluation. Seed buildup was done at Dookie Vic and Manjimup WA. The harvested seed was to be delivered to Shepparton on 10 April 2008, from which a bulk would be sent to AWCC for distribution to interested breeders by the end of April.Partially replicated trials, 2005 and 2006 lines
Lines from the 2005 and 2006 sets were increased in the Germplasm Evaluation Project during 2006. 25 seeds of each were sent to AWCC, of which 10 seed were to be kept and 15 seed sent to PBIC for rust testing. A further 1.5g sample was sent under GRDC-CIMMYT MTA to Grant Holloway at DPI Vic in May 2007 for yellow leaf spot testing. This will be augmented by DArT® profiling and LMA testing undertaken in the Coordination Project, to be completed mid-2008. Samples have also been distributed under GRDC-CIMMYT MTA to interested breeders as noted on the Coordination Project page.
The lines from the 2005 and 2006 sets were reduced, based on seed availability and rust scores on the 2005 set from Cobbitty. The resulting 2005 set now has 137 entries and the 2006 set 183, giving a total of 320 lines, for yield trial at 5 sites in a design with 190 entries replicated twice at each site, plus 10 checks, and 130 entries replicated once, with spaces for 20 checks:
- 2005 set reduced for partially replicated trial
- 2006 set reduced for partially replicated trial
- Sowing plans
These partially-replicated yield trials were sown by Agrisearch in May 2007 at the 5 sites agreed upon by the Australian breeders as representative of the regions:
| Site | Status 20 Sept 2007 | Status 22 Oct 2007 | Appearance 22 Oct 2007 |
| Birchip, Vic | Booting stage, looking good | The trial is water stressed but is expected to be harvested. When last visited on 14/10/07 it was at Z-65 to Z-71 stage. |  |
| Meckering, WA | Heading to anthesis stage, looking good | The trial is in a good shape and nearing maturity and it will be harvested in first week of November. |  |
| North Star, Nth NSW | Heading to anthesis stage, looking good | The best of the five trials, nearing maturity. Will be harvested the week of 29th Oct. |  |
| Red Banks, SA | Under stress, will need a good rain to progress further | The trial is water stressed but expected to be harvested. When visited on 13/10/07 it was at flowering stage. |  |
| Temora, Sth NSW | Booting stage, under stress, will need a good rain to progress further | This trial site is severely water stressed and the ear heads have struggled to come out of boot. This trial will not be harvested. |  |
Phenotyping to be done by Agrisearch as agreed
