Net necrosis of potato tubers associated with primary, secondary, and tertiary infection of leafroll

Abstract

Tuber net necrosis, caused by leafroll virus, was found to occur as a result of primary, secondary, and tertiary infection in six clones of potato (Solanum tuberosum L.). Differences were observed between clones in their reaction to the different types of infection. In most clones there was a higher percentage of net necrosis from primary than from secondary or tertiary infection. No significant difference was observed in the severity of the net necrotic symptoms due to the different types of infection.
