Abstract
Field survey was undertaken and 71 samples of chickpea wilted plants, were collected from 23 locations in different districts namely Bhopal, Raisen Rajgarh, Sagar, Sehore and Vidisha of Vaindhyao Plateau Zone of Madhya Preadesh. Out of 71 isolates, only 20 were found pathogenic to chickpea. These isolates were categorized into six different groups on the basis of growth pattern, colony diameter and number of micro and macro conidia. The physiological studies of the representative isolates of these 6 groups were made on seven solid media. All the media differed significantly from each other. The minimum mean growth (6.08 cm) was recorded in group 5 of isolates Ri4, Ri5 and V2 and maximum (7.86 cm) in group I consisting of B2, B3, Se6 and Se8. The maximum (6.28 cm) on yeast extract agar. These isolates exhibited three types of growth pattern namely fluffy, partially submerged and submerged. The maximum number of micro conidia were produced on PDA (7.61 million/ml) and minimum (2.60 million/ml) on nutrient agar. Similarly, the maximum number of macro conidia were produced on PDA (2.50 million/ml) and on nutrient agar.
