Diseased fruit samples were collected from different plants
in the infected orchard and preserved at the Plant Pathology
Division, Bangladesh Agricultural Research Institute, for further
study. Repeated isolations from the infected fruit were
made on potato dextrose agar (PDA, 39 g/L; Himedia, India)
after surface sterilisation with 70 % ethyl alcohol for 60 s
followed by three consecutive rinses with sterile distilled
water for 1 min. Whitish cultures developed with septate and
hyaline mycelia and elliptical to globose or irregular-shaped
sclerotia on the PDA medium (Fig. 3). Two isolates, JBdSs1
and JBdSs2, were obtained from separate samples. Typical
apothecia formed from sclerotia after conditioning with alternating
deep-freezing and normal temperature treatments for 3
consecutive days followed by 8 weeks of incubation on moist
sand in a petri dish (Fig. 4). The isolates JBdSs1 and JBdSs2
were deposited to the National Institute of Agrobiological
Sciences (NIAS) Genebank under the accession number of
MAFF244849 and MAFF244850, respectively.
