The Pyricularia Diversity Repository of Sri Lanka (PyDRSL)
The Pyricularia Diversity Repository of Sri Lanka (PyDRSL) presents an island-wide collection of blast pathogen isolates affecting rice and finger millet. The collection has been characterized based on colony morphology, Pot2-based DNA fingerprinting, mating type alleles, and race typing for selected avirulence genes. All data are freely available for research purposes and can be accessed at the Department of Botany, Faculty of Science, University of Peradeniya.
This project aims to gather surveillance data on major pathogens affecting economically important crops in Sri Lanka. We strongly encourage researchers to utilize our data for R&D to improve pathogen surveillance systems. The database is also an open platform for submitting new strain typing data, promoting collaboration.
This platform fosters a supportive network of plant pathogen surveillance stakeholders, working together to advance agricultural health.
