Sequence-tagged site-based diagnostic markers linked to a novel anthracnose resistance gene RCt1 in chili pepper (Capsicum annuum L.).

ABSTRACT: Anthracnose, caused by Colletotrichum spp. is the most devastating disease of chili (Capsicum annuum) in the tropical and subtropical regions of the world. The present study aimed at molecular mapping and development of markers linked to a new gene for anthracnose resistance in the chili cultivar 'Punjab Lal'. Phenotypic evaluation of F₁, F₂, and BC₁F₁ populations derived from a cross between 'Punjab Lal' and susceptible cultivar 'Arka Lohit' against a virulent isolate of C. truncatum revealed that anthracnose resistance in Punjab Lal is governed by a monogenic-dominant gene designated as RCt1. Forty-four (28 ISSRs and 16 AFLPs) out of 201 markers exhibited parental polymorphism and were used in bulk segregant analysis
