Protein profiling of Pongamia pinnata L. accessions

Abstract

Pongamia pinnata L. known as Karanja is gaining importance in Indian context as a renewable source of energy. The basic aim of this study was to establish the genetic relationship/ diversity in accessions of Pongamia pinnata based on protein profiling using SDS-PAGE. Dice similarity coefficient based dendogram generated two clusters. The cluster 1 embodied two accessions viz., G10 and G3. The second cluster was further divided into two sub-clusters. G18 was placed alone in first subcluster while second sub-cluster was divided into two groups. In first group 4 accessions i.e., G5, G11, G12 and G14 were placed. In second group 11 accessions i.e., G1, G17, G2, G15, G8, G16, G9, G4, G13, G6 and G7 were present. The information generated can very well be utilized in future Karanja improvement programme to produce elite/hybrid varieties with characters of importance.
