The landraces of Capsicum belonging to four major cultivated species, collected from various agro-ecological zones (AEZ) of Kerala were evaluated based on the ascorbic acid content and natural incidence of pests and diseases. Association of ascorbic acid was checked with 80 different characters comprising 40 qualitative and 32 quantitative characters, incidence of pest and diseases, species, horticultural type as well as AEZ differences. Association of bacterial wilt, dieback, mite, thrips and Spodoptera incidences with qualitative features was also evaluated. Species specific pigmentation and phenomics-based association patterns recorded in the present study will be helpful to sort out promising genotypes from a large pool of genetic resources and to fine tune selection criteria for ascorbic acid content and biotic resistance in chilli.
