Morphological variations in culture growth rate and pattern of different isolates of Colletotrichum capsici causing fruit rot and die back in chilli (Capsicum annuum) on different solid media

Five Colletotrichum capsici isolates belonging to two groups: (i) four from fruit rot and (ii) one of die back were collected from different conventional chilli-growing areas (blocks) of Ghaziabad adjacent district of NCR Delhi. Their morphological cultural growth were studied on different solid media. The maximum growth of isolate Ccfrs on CMA and OMA and rapid growth on all seven solid media, more virulent strain. Cc_FRBR showed the least growth in all tested media. Both two strains Cc_FRR and Cc_FRD resulted in less difference in growth for all the media and the same in morphologically resemblance in culture plates and natural fruits surface in field condition.
