Abstract

Seed protein banding patterns (SDS-PAGE) were studied from eighteen genotypes of chili pepper (Capsicum L). A total of 21 protein polypeptide bands with molecular weight ranging from 18.6 to 72.0 kD were recorded. Among the genotypes ‘CA18’, ‘CA21’ and ‘CA27’ represented maximum number of protein bands (12). Band no. (11) and (5,12) are exclusive to C. annuum L. and C. frutescens L. genotypes respectively. Average percent similarity was highest (100%) between ‘CA2’ and ‘CA8’ genotypes and the UPGMA dendrogram represented low genetic diversity. The study revealed that considerable intra and inter-specific differences were found in the genotypes. The variability of protein profiles in the genotypes suggested that these selected genotypes can be a good source for crop improvement through hybridization programs.
