In Wood apple the existing variability is low due to the problem of unexploitation and lack of awareness. However, to some extent variation is seen in the genotypes with respect to morphological, physico–chemical parameters and also in productivity. In any crop, the improvement by selection method involves identification of superior types from a genetic population. Thus variability in the population is a pre-requisite for crop improvement and is considered as a boon to a plant breeder. As variability makes pre - requisite for selection criteria, it is the most quickest and effective method of breeding, particularly in perennial crops. Hence, the present research was carried through survey of eighty six genotypes from selected districts of Karnataka like Bijapur, Belgaum, Haveri, Shivamogga, Davangere, Chitradurga and Tumukur district during the fruiting season of 2018-19. The trees were used for studying the physical characters and the observations on various parameters of tree were recorded. Among 86 genotypes surveyed, 49 genotypes were found small type, 27 genotypes were medium and 10 were large type of genotypes. The tree girth ranged from 18.00 cm to 230 cm with an average plant girth of 103.47 cm, 28 genotypes have light brown colored bark where as 58 genotypes have dark brown colored bark while, 40 genotypes and 35 genotypes are semi spreading and 11 genotypes were erect type of branching habit and 52 genotypes shown oval type of canopy and 34 genotypes exhibit round shape of canopy.
