Biochemical characterization of Arachis species of the section Arachis
Abstract
Thirty five accessions of 13 Arachis species belonging to the section Arachis were characterized for seed storage proteins and isozymes (peroxidase, esterase and glutamate oxaloacetate transaminase) banding pattern. The results of proteins and individual enzymes banding pattern were discussed and the cluster analysis based on cosine coefficient of similarity was done to ascertain the species relationship. High intraspecific variation was observed in banding pattern. Accessions of A. monticola, A. batizocoi, A. kempf meracadoi and A. correntina were found closely related to A. hypogaea and two accessions in the collection were found as duplicates based on these studies.
