Specific objectives of new GRDC project Specific objectives of new Specific objectives of new GRDC project GRDC project

Further confirmation and validation of newly identified novel sources of soil borne pathogen (SBP) resistance in high yielding advanced germplasm, with specific emphasis on multiple SBP resistance.

Breeding of these sources into Australian and CIMMYT bread wheat backgrounds, and delivery of SBP disease resistance germplasm through CIMMYT International Nurseries.

Molecular characterization of most promising novel sources of resistance for specific SBP with key linkages of useful populations with the AWBMMP.

Production of new mapping populations for Root Lesion Nematode and Crown Rot.

At least 2 years of field or greenhouse data are required for the SBP trait of interest to promote the line for distribution.

Key objective is the identification of multiple SBP resistant materials

Emphasis is placed on screening the high yield advanced lines from both the SW and WW international programs.

Australian colleagues are welcome to share germplasm for screening SBP in Turkey

  • Anything with 1 is as good as MR resistant check, while 1* is better.
  • To promote a MR line for CR at least 2 years GH and 2 years reliable field data is needed.
  • Should be able to identify the best lines based on this – eg Croc (SW) and Burbot-6 (WW)
  • Please see my comments regarding limitations and strength of GH vs Fld techniques

Mexico CROC_1/AE.SQUARROSA (224)//OPATA (CID 72726; SID 531; SH: CMBW91Y00935S-80Y-11KBY-1KBY-010M-1Y-2M-0Y-0SY) x Janz which has resistance to both RLN-Pt and CR. #

  • Furthermore several other valuable disease traits could be explored (FHS,

CR, YS, BP, SEPT).

  • This population has been partially mapped for RLN – Pt resistance two

resistance loci located on chromosomes 1B and 3B (Toktay et al., 2006

  • Genome. 49: 1-5).
  • This population belongs to CIMMYT and GRDC and can be utilised without

restriction for this project.

  • Planned to be phenotyped for CR and RLN-Pt this year in Turkey and Syria.

Other new mapping populations are planned for SBP as part of this project
