Genome based selection systems for baking quality and resistance in elite germplasm in winter wheat under moderate nitrogen fertilization. Subproject 2 (QR-on-Top)
Project
Project code: 2818200515, JKI-RS-08-3395
Contract period: 01.10.2016
- 30.11.2019
Budget: 121,627 Euro
Purpose of research: Applied research
Under the terms of the amendment to the German fertilizer ordinance, the restricted use of fertilizer will be a challenge to wheat breeders. Lower nitrogen fertilizer applications will reduce the protein content in winter wheat resulting in lower baking quality. Under these circumstances, increasing the protein quality of wheat varieties can compensate lower protein contents while maintaining high baking quality. Moreover, the requirements of new wheat varieties for resistances will be increased due to restrictions on pesticides and the emergence of new races for leaf and stripe rust and the ongoing demand for resistances to septoria tritici blotch and fusarium head blight. New selection methods, e.g. genomic selection, are expected to enhance selection gain for these traits in addition to grain yield in wheat breeding programs. The genetic and phenotypic analysis of a multi-parental population will give useful insights into the application of genomic selection strategies and provide genetic markers for major effect genes.
A multi-parental population will be phenotyped for grain yield and baking quality in multi-environment field trials. Resistance screenings for septoria tritici blotch, leaf and stripe rust will be performed under field and lab conditions. Genetic markers are going to be developed for new resistance genes. In addition to genetic mapping, genomic selection strategies for all traits will be established. For the prediction models, single markers or defined haplotypes can be used as parameters. The genetics of grain yield and baking quality will be analyzed in the context of reduced nitrogen application.
