, some doubled haploid (DH) (e.g. Gladius/Hamam-4) and RIL (Attila-7/Qamar-8, Attila-7/Hamam-4), Annuello x Qamar-8, Wyalkatchem x Qamar-8 mapping populations comprising of parents with drought tolerance and high yield potential, RWA tolerance have also been produced... In the project, the project team identified wheat germplasm with significant abiotic stress tolerance, in particular drought and resistance to biotic stresses and insect pests... The project leveraged on existing research network established by ICARDA with INRA, Morocco, EIAR, Ethiopia and ARC, Sudan which made substantial contributions to the project outputs...

The future of Australian wheat varieties is being determined, in part, by pre-breeding researchers who are successfully targeting some highly complex quality and production traits By Gio Braidotti Delivering improved wheat varieties to growers, and higher-quality grain to an increasingly diverse marketplace, is a process limited by the level of ingenuity that can be applied in the very first stage - pre-breeding... This intensive area of R&D activity not only identifies sources of novel genetic traits but also provides new techniques to transfer those traits to crop varieties... Pre-breeders are also aware of the need to help growers meet quality classifications that can earn valuable premiums, and also develop grains with new quality and health traits, such as biofortification and functional foods...

The loss to the wheat industry from these two nematode species has been estimated at $AU47 million/year for the northern region and $123 million for all Australia, based on average wheat production and price of $AUD239/tonne over a 10-year period to 2008 (Murray and Brennan 2010)... In order to obtain better sources of resistance to P. thornei we have screened two collections of wheat landraces from that area... We have also found resistance to P. thornei in a collection of wheat landraces made in in the early 1930's (Sheedy and Thompson 2009)...
