SUMMARY

Sorghum anthracnose disease is one of the major fungal disease of sorghum. The variability of different three districts isolates (Nine-9) of C. graminicola were studied on different culture media viz., potato dextrose agar, Richard’s agar, Czapek’s agar, malt extract agar, oat meal agar and sorghum seed extract agar. Potato dextrose agar, oat meal agar and malt extract agar supported maximum growth for all isolates. Isolate ST-1 showed maximum growth of 88.75 mm diameter on PDA and least growth on sorghum seed extract agar with least growth of 33.00 mm diameter in ST-2 isolate. Isolate NRM-3 recorded maximum growth mycelial diameter of 89.80 mm on oat meal agar and least on Czapek’s agar with 36.00 mm. Isolate BH-2 recorded maximum growth of 89.20 mm mycelial diameter on PDA and least on sorghum seed extract agar with 35.00 mm in BH-3 isolate.
