This study was established during two consecutive seasons of 2019 and 2020 in a private mango orchard situated at KomOmbo, Aswan Governorate (24° 28' 45.1596" and 32° 56' 28.626") where the texture of soil is clay and water table depth not less than two meters. Fifteen mango seedling strains age of trees ranging from 25 to 30- years old. They were planted at 6x6 meters; regular horticultural practices were carried out as usual. The growth, nutritional status, yield and quality of fruits of fifteen mango seedling strains were evaluated under conditions of Aswan region based on relatively better yield and fruit quality. The following strains of mango seedlings have been cultivated successfully, thirteenth, twelfth, eleventh and tenth strain in descending order under Aswan conditions. Also, through the numerical evaluation of the productivity characteristics and the fruit quality of the strains under study, it became clear that the tenth, eleventh, twelfth and thirteenth strains showed superiority, so they must be cultivated and spread them through vegetative propagation and expand their cultivation.
