Abstract: Chilli exhibits a wide range of variability in morpho-physiological traits. A logical way to start any breeding program is to collect precise information on the nature and degree of genetic divergence that would help the plant breeder in choosing the right type of parents for purposeful hybridization. The present investigation entitled was carried out at College Orchard, Department of Vegetable Science, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore with fourteen genotypes in order to study the variability for identifying the best performing chilli genotypes. Principal Component Analysis for the 32 morphological characters elucidated that, ten principle components with eigenvalues more than one accounted for 98.69 per cent of the total variability and the maximum variation was exhibited by the plant growth habit, anthocyanin colouration at nodes, intensity of anthocyanin colouration at nodes, leaf size, fruit colour at maturity unripened stage, fruit colour, fruit colour intensity, fruit sinuation of pericarp, branching habit, stem pubescence, stem pubescence intensity, fruit shape at longitudinal section whereas remaining traits exhibited low variability. Based on PCA and H’ the nine genotypes CC-CBE-005, CA-CBE-201, CA-CBE-202, CA-CBE-199, CC-CBE-004, CF-CBE-007, CC-CBE-001, CC-CBE-003 and CC-CBE-002 were identified as the most diverse genotypes.
