Most of the commercially grown apple cultivars in Pakistan require a cooler climate than all other fruits. Apple thrives
and fruits best under a relatively cool slow growing season, usually met with at higher altitudes. Varieties grown under
such conditions are Amri, Kashmiri Amri, Golden Delicious, Red Delicious, Sky spur, Banki, Kulu etc. Low chilling varieties such as Anna, Summer Gold and Golden Dorset have been identified giving encouraging results and hence can successfully be grown in lower elevations.
Fruits should be harvested at proper picking maturity. The time of picking will depend upon the degree of maturity which in turn depends upon the keeping quality of the fruit. Apples picked at immature stage results in poor quality and flavor, tend to shrivel and are subject to physiological disorders such as scald, bitter pit, soft and brown core. Fruits do not mature evenly on the tree; therefore, more than one picking are required. Avoid bruising and stem punctures. Picking should start from lower branches of a tree advancing towards the top. After picking apples should be put under cover in the coolest, well ventilated place. Apples may be packed in wooden crate, card board boxes, and cartons or in film bags. Before packing the fruit should be graded according to size and exterior quality of the apple. The length of post-harvest life during storage will depend upon the stage of maturation at harvest time, the length of the fruit remains at ordinary storage temperature and at cold temperature, season of picking and the variety itself
