Abstract

Anthracnose, caused by Colletotrichum spp. is a serious pre- and post-harvest disease in chilli (Capsicum annuum L.), which is a remunerative spice-cum-cash crop of India. An attempt was made to tag genomic regions controlling anthracnose resistance using reported microsatellite markers. Out of 60 polymorphic SSR markers screened, only four differentiated the individual constituents of resistant and susceptible bulks. Of these four, only one (HpmsE 081) was found associated with genomic regions controlling anthracnose resistance. However, the association was weak as suggested by low contribution of the marker towards the variance of response to anthracnose disease in terms of lesion size.
