This study was conducted during- 1999/2000  and - 2000/2001 seasons as an attempt to evaluate nine mango cultivars namely, Awaise Alphonse,
Balady, Aremanis, Goleck, Hindy Bisinnara, Mabrouka, Taimour and Tota pari grown under Sohag region conditions . Growth characters, yield incidence of alternate bearing , physical and chemical properties of the fruits , storage ability at room temperature and harvesting date were recorded for the nine mango cultivars . Results showed that there was a wide variation between the studied mango cultivars in relation to the parameters undertaken in this study . Mabrouka, Aremanis, Alphonse, Hindy Bisinnara, Awaise, and Tota pari mango cultivars produced the highest yield in descending order . the minimum yield was recorded in Goleck and Taimour mangoes. Trees of Alphonse and Goleck characterized by high alternate bearing, while trees of Awaise, Balady and Hindy Bisinnara mangoes characterized by low alternate bearing between the previous extremes. Trees of Aremanis , Mabrouka , Taimour and Tota Pari occupied an intermediate position. The highest storage ability was detected on fruits of Taimour mango . Fruits of balady and Alphonse trees had lower storage ability . Fruits of , Hindy Bisinnara , and Tota Pari ripened early and lately , respectively .Most of studied cultivars except Balady and Tota Pari had fruits with striking quality . Mabrouka, Aremanis , Alphonse, Hindy Bisinnara , Tota Pari and Awaise Mango cultivars are recommended to be cultivated successfully under Sohag region conditions , based on their higher yield and relatively better fruit quality .
