The Present study reveals the morphological and molecular variations in different accessions of Cordia dichotoma Frost F. a medicinally important plant collected from different locations of the Nanded district in Maharashtra, India. Morphological characterization of 10 year-old trees for 10 traits indicated wide variations among the accessions tested. Higher number of fruits per cyme and higher pulp: stone ratio was found in accession NCd7 colleted from Pawdewadi. Overall, NCd7 was found to be a superior germplasm line for most of the horticulturally useful traits among the accessions tested as it had higher percent of fruit set, pulp:stone ratio and fruit weight. High significant positive correlation was obtained between leaf, fruit characters and pulp:stone ratio. Moleuclar analysis was carried out using RAPD markers. Out of the five primers screened, a total of 45 scorable polymorphic markers were generated. Average polymorphism resolved by these markers among these accessions was 67.86 %. Genetic diversity revealed by Jaccard’s co-efficient was between 0.48–0.86. Study shows the existence of high genetic diversity among these accessions.
