After the plants have grown for 18 weeks, the nematodes are extracted from the soil and roots, and counted under a microscope to determine which plant lines have reduced nematode multiplication... Root-lesion nematodes (RLN) are considered most likely endemic to the Fertile Crescent region in the Middle East where wheat originated some 8,000 years BCE. From there, RLN probably spread around the world with grain cultivation across North Africa, Europe, America, and finally Australia... "We realised the resistances that aren't available in commercial wheats, do exist in their ancient ancestors," says Professor John Thompson, Crop Nematologist at University of Southern Queensland' who supervises the GRDC-funded wheat pre-breeding program into genetic options for RLN control...

The University of Sydney manages several collaborative programs with India funded through the Generation Challenge Program (GCP) and the Australian Centre for International Agricultural Research (ACIAR)... The programs develop germplasm with stress and disease resistance specifically for India by crossing Australian and local germplasm with subsequent selection for key traits using a combination of molecular markers and phenotypic screening... The materials, derived using a combination of double haploids and traditional selection, have been developed at the Plant Breeding Institute and the seed sent to India for evaluation...

The wild, ancient ancestors of wheat are a vital key to solving the problem of root lesion nematodes in Australia, researchers now believe... Northern growers currently have no commercial wheat varieties that resist the ravages of RLN, and the massive yield losses they experience each year are of great concern to the industry... Since there are no available commercial wheat varieties with resistance to RLN, choosing varieties that are tolerant, such as EGA Gregory , is a good first step in managing their populations (see the 2014 Queensland Wheat Varieties Guide )...
