To understand the role of chilli pungency in anthracnose development, inoculated 21 Capsicum cultivars with Colletotrichum spp. Anthracnose developed on inoculated fruits irrespective of pungency levels. Pearson's correlation between pungency and lesion diameter is 0.38 and P-value = 0.08. Capsicum baccatum PBC80 and PBC81 showed tolerance to Colletotrichum truncatum, C. plurivorum, C. gloeosporioides and C. fructicola while susceptibility to C. siamense pathotype 2. Natural grade capsaicin (NGC) significantly reduced C. truncatum growth (P-value = 5.26E-07, LSD = 0.07) in PDA. Breeding strategies needed to develop Capsicum cv. resistant against evolving pathotypes and to enhance capsaicinoids in the fruit pericarp to exploit antifungal potential.
