Analysis of seed protein of 29 lines of Capsicum annuum L. by polyacrylamide gel electrophoresis

Abstract

Proteins and enzymes are important parameters in biochemical taxonomy. Seeds of 29 lines of C. annuum from different sources and places of origin were studied. The protein content was estimated and SDS polyacrylamide gel electrophoresis technique was used to study the soluble protein pattern. Each genotype was distinct from the other, but, certain bands were shared by several genotypes. Average similarity was highest (80%) between accessions PBC 436 from Portugal and Round Ornamental collected from Kerala Agricultural University, suggesting that the material collected from India could have originated in Portugal. In general, Paprika lines had a high seed protein content and these also clustered together. Fruit length, fruit colour, and percentage of capsaicin did not show correlations with the clustering of the accessions.
