Analysis of variations in RAPD profiles among accessions of Prosopis

The genetic variability among accessions of Prosopis was determined using randomly amplified polymorphic DNA (RAPD) profiles. Similarities of profiles were determined using the algorithm of Jaccard, and UPGMA and neighbour joining trees were generated from the similarity data. The average similarity was highest among the accessions of P. glandulosa (0:52 0:18) and least in the accessions of P. juliflora (0:37 0:15), indicating that the latter species has greater diversity among accessions. Our observations suggest that RAPD analysis could help in identifying genetic variations among different accessions of Prosopis. [Goswami M. and Ranade S.
