Since time immemorial custard apple is intimately associated with humans. It is popularly known for their delicious fleshy fruit and lesser for antioxidant and antidiabetic activities. Because of its unique nutraceutical properties custard apple is widely cultivated throughout the globe. In view of this the present investigation was undertaken to study the morphological and fruit quality traits to define the available wide variability within the global custard apple germplasms. Accordance to this, the experiment was laid out in completely randomized design (CRD) with 30 selected genotypes as the treatments with three replications for each defined traits. The results showed that the wide variability was present among custard apple genotypes for quantitative as well as qualitative traits. The fruit shape ranged from round to cordate, fruit weight varied from 98.8 to 170.1 gm, fruit length varied from 5.47 to 7.0 cm, fruit width varied from 5.57 to 7.13 cm, fruit volume varied from 77 to 178 cm3 and pulp to seed ratio ranged from 3.69 to 32.87. Likewise, qualitative traits such as total soluble solids, total carbohydrate, free amino acids, dietary fiber, Ascorbic acid and total carotenoids were recorded and it also varied largely between the genotypes. Thus, results from the present study indicate that there is abundant natural genetic variability available within the custard apple genotypes which might offer suitable genetic material for future nutri-agricultural research.
