Managing on-farm Biosecurity risk in wheat through pre-emptive breeding
About
Involve phenotipic characterisatio of 150 Australian wheat varieties for resistence to Sunn pest and Hessian fly and further genetic manipulation to develop molecular markers for the above pests. Phenotyping for pests will be done at ICARDA's experimental sites in Lebanon and Morocco under greenhouse and field conditions.Development of molecular makers for Sunn pest and sent to AUstralia for phenotypic genotyping. Phenotypic characterization of 150 Australian wheat varieties for resistance to Sunn pest and Hessian fly. Phenotyping fot pests will be done at ICARDA's experimental sites in Lebanon and Morocco under greenhouse and field conditions. Evaluate twenty-one (21) SHW genotypes resistant to Sunn pest. Gene introgression of EPP gene resistence into Australian genetic wheat background. Phenotyping for SUnn pest resistence. Go/no-go decision dependent on results achieved. Develop doubled haploid (DH) line BC₂F₁ hybrids in order to fix favourable allelic combinations and supply genotypes carrying single and multiple resistence to EPP. Phenotyping for Hessian fly resistence.
Impact
Goals
Reduction in production losses by biotic agents as Sunn pest and Hessian fly. Evaluate twenty-one (21) SHW genotypes resistant to Sunn pest. Gene introgression of EPP gene resistence into Australian genetic wheat background. Phenotyping for SUnn pest resistence. Go/no-go decision dependent on results achieved. Develop doubled haploid (DH) line BC₂F₁ hybrids in order to fix favourable allelic combinations and supply genotypes carrying single and multiple resistence to EPP. Phenotyping for Hessian fly resistence.
Objectives
Screening and Genetic manipulation of Australian wheat varieties for resistance to Sunn pest and Hessian fly. The project aim and research activity are mainly focused on genetic improvement of Australian wheat varieties regarding Sunn pest and Hessian fly diseases. The first analysis and selection will be made in Morocco and Lebanon under greenhouse and field conditions. In Australia, thanks to similar environmental characteristic with already mentioned country, after gene introgression in Australian elite varieties, the best genotypes will be selected.
Impact pathways
In Australia, thanks to similar environmental characteristic with already mentioned country, after gene introgression in Australian elite varieties, the best genotypes will be selected. The benefit will be mainly at economic, social and environmental level. The new varieties will contribute to help farmers having constant harvest and reduce food risks caused by biotic stresses. The reduction of losses will revitalize rural communities and minimize rural to urban migration. The use of resistant genotypes will result in less application of fungicides, pesticides and insecticides by farmers. These will protect the environment and enhance generation of biological diversity.
