Abstract

Pongamia pinnata is an oil-producing tree species with multiple uses and considerable potential as a bioenergy crop. This investigation was carried out to assess the extent of genetic structure in a representative set of 226 individuals of Pongamia pinnata encompassing seven populations as a prelude to utilization of promising and genetically divergent material in breeding programmes. Molecular polymorphism was 67.18% with ten inter simple sequence repeats (ISSR) between the individuals indicating modest levels of genetic variation in the Pongamia pinnata germplasm collected. The within-population variation based on ISSR polymorphism was 32.34% and polymorphism at the species level was 94.3%. Genetic differentiation between populations (GST = 0.61) was positively correlated with geographical distance. The data obtained indicate an immediate need to widen the genetic base of Pongamiapinnata germplasm for proper characterization, and for extensive plantations of elite varieties to meet the demands for biodiesel.
