New marker information

We've recently posted some new marker information at www.markers.net.au.
  • Barley: Markers for a 7HL QTL for resistance  against Pratylenchus thornei
  • Wheat: A new marker for a 6DS QTL for resistance against Pratylenchus thornei
  • Wheat: Markers for a Sentinel-derived 2B QTL for resistance against crown rot.
  • Wheat: An update from Daryl Mares on preharvest sprouting.
See below for further details.

To access the marker information, pre-breeders and breeders in Australia can go to www.markers.net.au and login to the MEMBERS AREA. If you don't have a userid, you can request one there.

Barley

Markers for a QTL for resistance against Pratylenchus thornei

We mapped a very significant QTL on 7HL in two populations. Three linked markers are provided to track the haplotype from the more resistant parents.

Wheat

A new marker for synthetic-derived resistance against Pratylenchus thornei

With just one marker that maps in a QTL region on 6DS, five resistant synthetic hexaploids can be distinguished from all of the bread wheat lines we have tested.
[PROJECTS UA00143 and UA00157]

Markers for Sentinel crown rot resistance QTL

We mapped SNP markers near a QTL on chromosome 2B. We recommend three of these markers as being useful to select for the resistance allele from Sentinel.

Markers for resistance against pre-harvest sprouting 

Daryl Mares has provided an update on outputs from research on preharvest sprouting, with spreadsheets showing marker haplotypes and variety survey results

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.
