Abstract
The present study was conducted to estimate the genetic relationship between the three cultivars of wax jambu (Syzygium samarangense) Giant the 'Green', Masam manis 'Pink' and Jambu madu 'Red' cultivars grown under the agro climate conditions of Banting, Selangor, Malaysia. Various morphological characteristics like tree height, canopy width, shape, foliage density, color and phyllotaxy, leaf length, wide, shape, orientation, drymatter, moister percentage and flagrant, flowering time, color, bud/cluster, panicle length, number of anthers and carpels per flower, filament and style size and inflorescence position, fruit shape, size, surface, weight, maturity time, dropping and yield, seed number and juice percentage were taken into account and variation in the characteristics has been discussed. Large variability has been observed in all morphological and physiological characteristics of three cultivars and that was due to their different genetic makeup.
