| dc.description.abstract | With the large scientific strides made in recent years when it comes to genome sequencing, techniques for plant breeding based on genomic data is on the rise. With the ever-changing environment and the increase of pesticide-resistance in pathogens, new technologies for protecting yield must be found. Mapping of resistance loci for various infectious agents is a relatively novel technique that shows great promise for the advancement of breeding for disease resistant crops.
In this thesis, the focus has been to map resistance QTLs in wheat for the fungal disease Septoria leaf blotch. Phenotypic and genotypic data encompassing six years of field trials in the 2012-2022 period has been analysed and compared to find important resistance QTLs. While several QTLs were found overall, three major resistance QTLs showing great consistency over the years were identified, of which two were previously known and one appears to be novel. Hopefully these QTLs can be used in breeding, and the data used to identify more resistance loci in the future. | |
