Surveys were undertaken for characterization and evaluation of genetic diversity of Jamun (Syzygium cumini L.) of seedling origin for different horticultural traits during 2013 and 2014 in the Jamun growing areas of Jammu sub-tropical areas. Investigations were undertaken during the entire reproductive phase to assess the distribution, range and to record the range of genetic variability of different horticultural traits on the selected forty trees. Mature fruits were harvested and analyzed for different fruit characteristics. Results of evaluated Jamun genotypes showed wide variability for studied characteristics. | Studies on variability of seedling origin jamun Syzygium cumini L.
