An alkali maceration technique has been developed to detect internally seed‐borne inoculum of Peronosclerospora sorghi in sorghum seeds. Optimum period for maceration was found to be 36 h. Oospores in the glumes and mycelia in the pericarp and endosperm were clearly demonstrated. Mycelium was found in the pericarp of 40 % of the seeds tested and in the endosperm of 5 % of seeds. The possibility of using this technique to detect seed‐borne downy mildew infection has been emphasized.
