Abstract
Collection of diseased samples from different locations of Bhind, Morena and Gwalior districts of Madhya Pradesh for determining variability among collected fifteen isolates of Alternaria solani, the causal agent of early blight of tomato based on conidial morphology, cultural variability (color of mycelium, growth of mycelium) on PDA media. Out of fifteen isolates, five isolates were found brownish black, four isolates were found greenish black and three isolate were found reddish black and dark black colour of mycelium. On the basis of type of mycelial growth the isolates were categorized, seven isolates grew with irregular margin and rough surfaced colony, five isolates grew with circular margin and smooth surface, two isolates grew with irregular margin and smooth surface and one having circular margin and rough surface. The maximum conidial length was occurred in isolate MRN-2 and conidial width was in the isolate MRN-2. Maximum number of horizontal septa was associated with the isolate MRN-2 and least septation was observed in isolate GWL-2. The number of vertical septa was higher in the isolate MRN-3 and least was noticed in the isolate GWL-1.The maximum beak length was associated with the isolate BND-2 and least beak length was observed in the isolate GWL-4.
