Abstract
Peronosclerospora sorghi establishes in sorghum seeds either directly from the mother plant or by conidial infection through stigma, style and ovary. Infection through the mother plants leads to various degrees of earhead sterility whereas the conidial infection through carpels does not induce any sterility in the earhead. Infection can take place only during stigma emergence stage and mycelial infection is noticed in pericarp and aleurone layer in about 30% of the seeds. The fungus established in the embryonic tissue only in 0.5% of the seeds. In the transmission studies, direct correlation is noticed between embryo infection and seed transmission of the fungus.
