Summary

A study of the morphological variability among 25 different collections of sugarcane smut fungusUstilago scitaminea from the States of Delhi, Uttar Pradesh, Bihar, Madhya Pradesh, Maharastra, Andhra Pradesh and Madras revealed that considerable variation exists in spore size, colour, spore-wall markings of the isolates. On the basis of statistically significant differences in the spore size, the 25 isolates can be classified into 4 distinct groups. Three types of spore-wall markings viz., verrucose, punctate and echinulate are met within the isolates studied. There is no appreciable difference in the spore wall thickness of the different isolates. Spore colour of the different isolates varied from yellow to brown with several shades in between.
