Abstract:

Diseased sesame samples were collected from the major growing regions of Andhra Pradesh for molecular and cultural characterization of Alternaria sesami. The collected isolates were characterized based on their conidial length, breadth and beak length and cultural characters (colour of the mycelium, growth on the PDA medium). Of the 12 isolates, most of the isolates were white in their colony colour which later turned into grayish brown, while a few isolates were brown with fluffy growth at the centre. After seven days of incubation highest mycelial growth was observed in NP 2 isolate (5.28 cm) isolate which was followed by EL 2, NAR 1 (5.27 cm). Average conidial size of the A. sesami is 24.88 - 34.64 µm X 9.61 - 12.13 µm with beak length of 5.12 - 8.32 µm and no. of horizontal and vertical septa varied from 2.76 - 3.82 and 1.31 - 1.76 respectively.
