Seeds, Rootstocks & BreedingWhy do long mango disease-screening programs recheck the aggressiveness of their pathogen cultures?
The challenge organism can change during maintenance, making later tests less comparable with earlier ones. A long-running mango screening study replaced an isolate after it lost virulence. Include an appropriate susceptible reference and verify the challenge before ranking candidates. Otherwise reduced disease across the experiment might be mistaken for widespread host resistance rather than a weaker inoculation test.
