Viability of Seed in Coriander Infected by Protomyces macrosporus Unger

The fruits of coriander (Coriandrum sativum L.) collected from stem gall infected plants indicate comparable viability and germinability of seeds on testing with triphenyl tetrazolium chloride (TTC) and germination, respectively. Systemic invasion by the pathogen considerably reduces germinability of the seed from these plants. The seedlings raised in the latter test, however, show infection on the stem due to incipient carriage of the pathogen through the integuments, thus adding to the primary inoculum potential of the disease.
