Suggest materials for genetic analysis
In preparation for meetings of its steering committees for wheat (in March) and barley (in April), the Genetic Analysis project ('GA') of the Australian Wheat and Barley Molecular Marker Program invites your suggestions of materials to be developed, genotyped and/or phenotyped by the project. If you would like to nominate: (1) existing materials for use by GA and/or (2) parents or parent/combinations for which GA could develop materials please do so by 11 March 2014. For details on what information to send, see 'Nominate materials for GA' below.

New: exome capture
Exome capture for wheat and barley is now available to GRDC-funded pre-breeding projects. For more information on this and other technologies/capabilities available through DAV00127 next-generation genetics project, contact kerrie.forrest@depi.vic.gov.au.

Nominate materials for GA
For each set of materials nominated, please send an email to diane.mather@adelaide.edu.au by 11 March 2014 with the following information:
- CROP: bread wheat, durum or barley
- MATERIALS: For existing materials, any information you have on their pedigrees and breeding history, ownership, population size, previous phenotyping and/or genotyping and seed supply. If you are proposing that GA develop new materials, provide similar information for the proposed parents.
- RATIONALE: Evidence that these materials would be useful for genetic analysis (e.g. evidence of variation for nationally or regionally important traits*).
- PHENOTYPING: If the materials will be ready for phenotyping in 2014 or 2015, indicate whether any plans are already in place for phenotyping in other projects and whether phenotyping support is required from GA.
* What traits? GA maps loci that affect important traits and develops markers for use in Australian winter cereal breeding and pre-breeding. Most of our targets are biotic stress traits, but we also do some work on wheat quality traits. Feel free to suggest any important trait, as long as the work is not being covered by other projects. For example, we do not work on rust resistance, as this falls within the mandate of the Australian Cereal Rust Control Program. In bread wheat, our biotic stress targets to date have been resistance against cereal cyst nematode (the Cre8 locus) and root lesion nematodes (the Rlnn1 locus for Pratylenchus neglectus and synthetic- and landrace-derived resistances for P. thornei), resistance against Stagonospora nodorum (using synthetic sources), resistance against tan spot (yellow leaf spot; in collaboration with a project led by Manisha Shankar) and resistance against crown rot (in collaboration with the Crown Rot Initiative). Recently, we have begun work on tolerance against P. thornei. In barley, our targets to date have been resistance against cereal cyst nematode and resistance against powdery mildew, net form net blotch, spot form net blotch and scald.

New publications
We are happy to announce two new publications that report on results from AWBMMP research:
- Jayatilake, D, Tucker, E, Bariana, H, Kuchel, H, Edwards, J, Chalmers, K & Mather, DE 2013, ‘Genetic mapping and marker development for resistance of wheat against the root lesion nematode Pratylenchus neglectus’, BMC Plant Biology , vol. 13, no. 230. This Open Access article is available at http://www.biomedcentral.com/1471-2229/13/230. The Rlnn1-linked marker that was released to breeders and pre-breeders as uat0002 is published here as wri2. If you have been using uat0002, please rename it to wri2 (and cite our article if you publish any results!)
- Wallwork, H, Grcic, M, Li, CD, Chalmers K & Mather, DE 2014, ‘Use of specific differential isolates of Rhyncosporium commune to detect minor gene resistance to leaf scald in barley seedlings’, Australasian Journal of Plant Pathology Published on-line in December 2013. (DOI 10.1007/s13313-013-0264-5)
This newsletter:
Several times a year, the Australian Wheat and Barley Molecular Marker Program informs user groups about recent discoveries, new marker and new technologies. To avoid being a nuisance to those who are not interested, we only send the newsletter to those who subscribe. If you know someone who might be interested, please suggest that they visit www.markers.net.au and click on NEWSLETTER.
