Abstract

Aim: The present study was conducted with the aim to collect and evaluate the available genetic diversity of chilli (Capsicum annuum L.) in order to identify promising accessions for cultivation as well as use in crop improvement.???

Methodology: A total 78 accessions of chilli were collected from Western himalayan region, i.e., Kashmir valley of India. Collected germplasm was evaluated at one location for fifteen quantitative traits of horticultural importance.??? ?????

Results: With ample diversity in these traits, a high coefficient of variation was found. Principal Component Analysis (PCA) revealed that first five principal components possessed eigen value > 1, cumulatively contributed > 65.2 percent of total variability. All the genotypes were grouped into five clusters showing non parallelism between geographic and genetic diversity. ????????????

Interpretation: The genotypes grouped in different clusters may be utilized for hybridization programme to produce more heterotic recombinants. ????????????

Key words: Capsicum annuum, Genetic variability, Germplasm, Single linkage cluster analysis
