Characterization of Jamun genotypes in central and submontaneous Zone of Punjab

Jamun (Syzygium cumini Skeels.) is an under exploited indigenous fruit tree of India.The variations act as an important source and are a prerequisite for a tree breeder in breeding methods to improve a species. To collect the variability with the aim of selecting some superior types/strains a survey was carried out in Amritsar, Gurdaspur and Pathankot Districts, in which 25 seedlings of jamun were evaluated for their physical characteristics and biochemical composition during 2015-2016 respectively. The data revealed that the maximum tree height (24.38m) and canopy volume(3897.56 m3) was measured in GD-19 genotype Maximum fruit length(3.58 cm),breadth (2.75 cm) and fruit weight (14.88 g) was registered in GD-6 genotype. Among bio-chemical  characters it was estimated that  maximum total sugars ( 21.34 %) was recorded  in PS-1 genotype and reducing sugars (14.64 %) was recorded in AJWR-14 genotype.
