Development and validation of molecular markers tagging anthracnose resistance in white lupin (Lupinus albus, L.)

Summary in the original language of the document

White lupin (Lupinus albus, L.) has great potential to be utilized more in organic and sustainable agricultural systems. However, there are major obstacles in the production of this crop to overcome. One of these is the susceptibility against its main fungal pathogen, Colletotrichum lupini, which causes anthracnose disease, representing a serious threat to lupin cultivation worldwide, potentially leading to total yield loss in Swiss growing conditions. The trait of anthracnose resistance is polygenically controlled in white lupin, no complete resistance was observed and only few sources of resistance were identified until now. Efforts are constantly made to breed cultivars with increased resistance. To achieve this goal, developing and validating molecular markers for direct application of marker assisted selection (MAS) and genomic selection (GS) in variety development is pivotal.
