Genetic diversity in Spodoptera litura (Fab.) from major soybean growing states of India

Random Amplified Polymorphic DNA molecular markers analysis of Spodoptera litura larvae population from seven major soybean growing regions of India revealed, populations from Hyderabad and Indore, shared cent per cent similarity, Pune and Parbhani populations showed 90 per cent similarity, Adilabad population shared 83 per cent similarity with both Hyderabad and Indore populations, while Dharwad and Belagavi populations showed 72 per cent similarity. The lowest genetic similarity value was observed between Dharwad and Parbhani populations (46%). It is clear from the similarity analysis more than 46 per cent similarity between populations of the S. litura from major soybean growing states, demonstrat emediocre genetic differences between the populations. Thoughmuch genetic diversity was not observed between S. litura populations, topological and temporal factors perhaps influenced the existed diversity among the populations.
