Abstract

Seed infection and transmission of Pseudomonas solanacearum on groundnut.

Abstract

Seeds were harvested from wilted, infected plants of 8 Indonesian cultivars grown on infested land. Some of the harvested pods were rotted or discoloured; others appeared healthy. Discoloration was also seen on the seed. Bacterial colonies were isolated from different parts of infected seeds. Seedlings grown from seed of infected plants in sterile soil wilted in 2-4 weeks at rates of 5-8%. These results provide further evidence of transmission of P. solanacearum through groundnut seeds. This paper was presented at an ACIAR/ICRISAT collaborative research planning meeting on bacterial wilt of groundnut held at Genting Highlands, Malaysia 18-19 March, 1990.
