Abstract:

Brinjal (Solanum melongena L.) also known as eggplant is a popular vegetable crop grown worldwide. The most destructive and important disease on brinjal is fruit rot incited by the fungus, Phomopsis vexans (Sacc. & Syd.) Harter. The fruit rot adversely affects the fruit quality and quantity reducing the market value. A total of 20 isolates of P. vexans were obtained from Ri-Bhoi district of Meghalaya. All the isolates were found pathogenic to brinjal. The isolates showed significant variations in colony colour, shape, zonation and consistency in the media viz., Potato dextrose agar (PDA), Malt extract agar (MEA), Richard’s synthetic agar (RSA) and Czapek’s dox agar (CDA). The maximum average growth of all the isolates was supported by PDA medium (8.58 cm). The highest biomass production was recorded in isolate Pv21 (393 mg) and the lowest in isolate Pv12 (163 mg). Alpha (α) and beta (β) conidia were also observed in all the isolates. Among the isolates, α conidia size was maximum in isolate Pv5 (8.9x3.4µm) and minimum in isolate Pv15 (4.9x2.8µm), whereas β conidia size was maximum in isolate Pv17 (23.56x2.26µm) and minimum in isolate Pv4 (14.88x1.27).
