Coping with Stress

Aussie wheat breeders need stronger varieties adapted to increased heat and drought stress.

2015 - Goal Set

Identify new yield and protein quality markers to generate new climate-adapted seed or new digital databank.

Breeding information icon
73 Varieties

Selected from hot and dry sites worldwide.

Criss Cross

World collections crossed with Aussie varieties Scout and Gladius leading to around 3,000 plants and 9 field trials

Get Choosy

Promising new plants cope well in hot and dry conditions, produce high yield and strong protein quality. Such characteristics (traits) are called phenotypes.

Characterise

Combining genetic data and phenotype changes, we can see which characteristics are from each parent, thus giving us guiding markers.

Breeding information icon
New and Adapted

Most important markers were linked to traits such as high yield and improved protein quality.

Share to Breeders

Almost half a decade later, we now have 35 million SNP data points (markers) identified from the new plants, enabling breeders to select more specifically to suit the Australian climate.
