Analysis of variations in RAPD profiles among accessions of Prosopis

The genetic variability among accessions of Prosopis was determined using r andomly amplified polymorphic DNA (RAPD) profiles. Similarities of profiles were determined using the algorithm of Jaccard, and UPGMA and neighbour jo ining trees were generated from the similarity data. The average similarity was highest among the accessions of P. glandulosa (0.52 +/- 0.18) and leas t in the accessions of P. juliflora (0.37 +/- 0.15), indicating that the la tter species has greater diversity among accessions. Our observations sugge st that RAPD analysis could help in identifying genetic variations among di fferent accessions of Prosopis.
