Coconut breeding methods

Cocos nucifera L. is a perennial multipurpose palm grown widely in the humid tropics. It provides nutritious food and refreshing drink, edible oil and nonedible uses, fiber of commercial value, shells for fuel and industrial uses, timber and a variety of miscellaneous products for domestic and industrial uses. It is grown mainly in coastal areas and island ecosystems sustaining the livelihood of people and protecting the environment. Varieties: There are only two distinct varieties of coconut, the tall and the dwarf. The tall cultivars that are extensively grown are the West Coast Tall and East Coast Tall. The dwarf variety is shorter in stature and its life span is short as compared to the tall. Hybrids are the intervarietal crosses of two morphological forms of coconut. They show earliness in flowering and give increased yield, higher quantity and better quality of copra and oil when compared to the parents. When the tall is used as female they are called TxD hybrid while the reciprocal is known as DxT hybrid. Hybrids perform well under good management conditions including nutrient management and irrigation.
